7 mm / 0.28 in Zamak Bra Strap Slider and Ring 2-Piece Set PIR700007Z

7 mm / 0.28 in Zamak Bra Strap Slider and Ring 2-Piece Set is a sourcing-focused format for lingerie and swimwear manufacturers that repeatedly consume one slider and one ring in the same approved construction. The e-buttons version emphasizes purchasing clarity, set-to-piece conversion, warehouse control and repeat-production consistency. One set contains 1 slider + 1 ring; a hook is not included.

Set contents and core function

This 2-piece set contains one bra strap slider and one ring in the same sales unit. The slider is used to adjust usable strap length, while the ring creates a connection or direction-change point in the strap construction. Both parts belong to the nominal 7 mm / 0.28 in hardware family and are classified as Zamak. A hook is not included. The set format is intended for production workflows where one slider and one ring are repeatedly consumed together and need to be managed under one sourcing and inventory item.

How to read 7 mm / 0.28 in

The 7 mm metric value identifies the nominal hardware family and 0.28 in is the approximate imperial equivalent. Actual strap tape can vary in finished width, thickness, elasticity, weave density and edge firmness even when the nominal label is the same. Size should therefore be treated as the first sourcing filter rather than final proof of fit. The correct approval method is to assemble the hardware with the exact tape intended for production and review the completed strap sample.

Role of the strap slider

The slider allows the tape to travel through the hardware in a controlled route so the usable strap length can be changed. The tape should not bind, twist or move too freely. Stitching should not block the movement zone, and folded tape should not create excessive thickness near the hardware. Testing both the shortest and longest intended adjustment positions on the approved sample helps confirm that the slider and tape work together as expected before a larger production run begins.

Role of the ring

The ring is a connection component rather than an adjustment component. It can connect the strap to another section or redirect the strap path. When tape is folded and stitched around the ring, the total thickness increases, so the fit should be checked for bunching or excessive play. Ring angle can also influence how the finished strap sits on the garment. Evaluate the ring in the completed construction rather than only on a flat table.

What Zamak tells you

Both components are classified as Zamak. This describes the base material category but does not independently establish plating thickness, corrosion resistance, saltwater performance, wash life or chemical resistance. Those properties require verified test data. If the finished product has special environmental, care or finish requirements, the complete textile-and-hardware system should be tested under the intended conditions before production is approved.

Bras and bralettes

In narrow bra and bralette straps, the slider can provide length adjustment while the ring can form the connection to another strap section or garment point. Strap direction, fold allowance and seam placement affect how the two components sit in the finished garment. Hardware that works correctly in one construction should not automatically be assumed to behave the same way with another tape or sewing method. Record the approved tape and assembly details whenever possible.

Bikinis and swimwear

Elastic swimwear tapes can change width and thickness under tension. A slider that moves correctly on a relaxed sample may create more friction when the tape is stretched, and the ring may rotate to a different angle. Review the completed sample both relaxed and under representative light tension. This is a mechanical fit check only and should not be interpreted as a claim about chlorine, saltwater, sunlight or coating durability.

Set or single components?

The set format can simplify purchasing and material issuing when every finished garment consistently uses one slider and one ring. If a style requires only one of the two components, the corresponding single-item product may be more flexible. Choose the buying format according to the actual bill of materials rather than simply grouping more hardware under one code. This helps avoid unused components, inventory confusion and inaccurate repeat orders.

A hook is not included

This product contains one slider and one ring only. A hook is not part of the set. If the garment construction requires a hook, that component should be sourced and recorded separately. Clear package-content language is important because the word “set” can describe different quantities in different hardware families. Purchasing, warehouse and production teams should all understand the physical contents of one sales unit.

Test both components on the same strap

Before bulk production, test the slider and ring together on one completed strap made with the actual production tape. Check slider movement, ring angle, folded thickness and stitch distance at the same time. Separate component checks are not enough because tape thickness and elasticity can affect the two pieces differently. If the tape supplier or production lot changes, make a short verification sample instead of assuming the previous approval remains valid.

Strap routing and stitch distance

The tape should follow the intended route through the slider without twisting. A stitch line placed too close to the movement area can interfere with adjustment. Around the ring, the fold should create a stable connection without excessive bulk. Record the approved routing, fold allowance and stitch distance on the technical sheet so different operators can reproduce the same construction. Repeatable assembly details are part of the production standard, not just the choice of metal hardware.

When the tape supplier or lot changes

A new tape lot may have different thickness, elasticity or surface friction while still being sold under the same nominal width. Small textile changes can affect slider movement and ring position. Before releasing the new lot into full production, compare it with the approved reference. Check movement, fold thickness, ring angle and seam position. If behavior differs, update the assembly approval rather than forcing the old settings onto the new tape.

Technical sheet and BOM

The technical sheet should identify the item as a 2-piece set containing one strap slider and one ring, nominal size 7 mm / 0.28 in, and Zamak material. Include the approved strap-tape reference and assembly notes where possible. Consistent naming across purchase orders, warehouse labels and production sheets reduces confusion with single components, different size families or visually similar hardware.

Warehouse and inventory logic

Set inventory should remain separate from single-slider and single-ring inventory. Because one set contains two physical components, an order of 500 sets means 500 sliders plus 500 rings, or 1,000 physical metal pieces. “500 sets” and “500 pieces” are not the same quantity. Shelf labels should show the set type and contents, not only the 7 mm size, to reduce picking errors during fast production preparation.

Quality-control approach

Quality control should verify that both components are present, show no obvious deformation and perform correctly in the completed strap. Compare slider movement, ring orientation, fold position and overall visual balance with the approved sample. If behavior changes during production, review the tape lot, assembly direction, stitch distance and fold method together before assuming that the metal part itself is defective.

Signs of a mismatch

If the tape binds, twists or slips excessively in the slider, or if the ring feels too loose, rotates unexpectedly or pulls the strap into an unwanted angle, reassess the complete tape-and-hardware relationship. These symptoms do not automatically prove a defective component. Tape thickness, elasticity, surface friction, fold method and seam placement can create similar effects. Comparing the problem sample with the approved reference is the fastest way to locate where the difference begins.

Production quantity planning

The minimum order is 500 sets. If one set is used per finished garment, 500 sets theoretically support 500 garment units before accounting for samples, quality-control pieces, process loss or internal safety stock. Demand may be consolidated when several styles or sizes use exactly the same approved set. Different hardware sizes or material families should not be combined into the same requirement simply because the products serve a similar function.

Repeat-order identification

Avoid generic repeat-order descriptions such as “small bra set.” Keep the full definition: 7 mm / 0.28 in, Zamak, 2-piece set, one slider plus one ring. An archived approved strap sample or a clear reference image can help future purchasing and production teams identify the correct item months later. This discipline becomes especially valuable when several narrow hardware sizes and geometries are stored in the same category.

Care and finished-product limits

Final care instructions should consider the entire material system: textile, elastic tape, thread, dyes, surface finish and other hardware. Without verified testing, no blanket guarantee should be made for washing, corrosion, saltwater or chemical exposure. Manufacturers should validate the completed product according to the intended end-use and their own quality requirements.

Compare with the live single-component options

Manufacturers that need separate inventory can source the 7 mm / 0.28 in Zamak Bra Strap Slider and 7 mm / 0.28 in Zamak Bra Strap Ring as individual items. Other sizes and hardware formats can be compared in the Bra Rings, Hooks and Strap Adjustment Buckles category.

Protect set integrity in bulk production

When the set is issued to production, confirm that both pieces come from the approved 7 mm / 0.28 in Zamak family. Small sliders and rings can look similar during fast warehouse picking. Checking the first completed straps against the approved sample helps catch a wrong size or geometry before it is repeated across a larger order.

Keep set inventory separate from single items

A set contains two physical components but remains a distinct sales and inventory unit. Converting set stock into separate slider and ring stock without a controlled process can create quantity discrepancies. The warehouse method should ensure that an order for 500 sets is fulfilled as 500 sliders and 500 rings from the correct approved family.
