20 mm / 0.79 in Zamak Wide-Body Bra Strap Slider and Ring 2-Piece Set groups the main Zamak components for a 20 mm / 0.79 in strap construction into one 2-piece set. The physical package contains 1 wide-body slider + 1 ring. Buying the components as a set simplifies BOM planning, but final production suitability still depends on the actual strap tape, seam method and connection geometry used in the finished garment.
Understanding the 20 mm / 0.79 in set
The nominal size describes the strap-width class, not a universal fit guarantee. Tape thickness, weave density, surface friction, elasticity and folded construction can all change how the metal pieces behave. Every component in the set should therefore be tested with the actual production tape. If the tape binds, bunches, feels excessively loose or causes unwanted rotation, review the combination before bulk production.
Reading the package count correctly
The set is one commercial item but contains 2 separate physical metal components: 1 wide-body slider + 1 ring. Purchasing, warehouse and production teams should distinguish set quantity from individual-piece quantity. A 500-set order requires the correct number of each component according to the set recipe. Keeping this distinction clear reduces inventory and consumption errors.
Why the wide-body slider has its own set
The slider in this set is the wider-body 20 mm / 0.79 in model rather than the standard-body version. Both share the same nominal strap class, but the visible metal proportion and body geometry are different. The wide-body set should therefore remain a separate approved SKU in technical packs, warehouse labels and repeat orders.
How the two-piece set is intended to work
The two-piece set combines a slider and a ring. The slider adjusts usable strap length while the ring creates a connection and direction-change point. A hook is not included. If the garment design requires a hook-style connection, that component must be selected separately or the three-piece set should be considered.
Different functions inside one strap system
The slider controls usable strap length and the ring provides a connection and direction-change point. Equal nominal width does not make these pieces interchangeable. The technical pack should identify the role of each component so assembly operators do not substitute one function for another.
Zamak material classification
The metal components are classified as Zamak. That describes the material family; it does not by itself establish coating life, corrosion resistance, wash durability or chemical resistance. If a garment program has specific performance requirements, confirm them through separate test results or quality documentation instead of assuming them from material name alone.
Use in bras, bralettes and swimwear
The 20 mm / 0.79 in class can be used in wider bra, bralette, bikini and swimwear strap constructions. Final suitability depends on the complete design. Swimwear and lingerie tapes can differ significantly in stretch, thickness and surface behavior, so the same metal set should be rechecked whenever the strap material changes.
Tape routing and seam placement
Seams near the slider should leave enough room for the intended adjustment movement. Folds around the ring should sit flat without excessive bulk. In the two-piece layout, preserve the approved routing between slider and ring. Seam distance should follow the approved sample rather than a generic rule that ignores the actual tape construction.
Finish options
The family uses Nickel, Black Nickel and Gold finish options. Planning all pieces of the set under the same finish supports visual consistency on the completed strap. A finish shown with zero option stock should not be treated as immediately available inventory. Check current option quantity before committing a production schedule.
Recording the set in the bill of materials
The set can be listed as one purchasing line, but the physical contents should still be written out in the technical pack. This tells production exactly how many metal pieces are expected and what each part does. Recording size class, Zamak material, set type and product code together improves traceability across sourcing, receiving and sewing.
Recommended sample-approval sequence
Start with the actual 20 mm / 0.79 in production tape. Route the tape through or around each component according to the intended construction, complete folds and seams, then inspect adjustment, orientation and visual balance on the finished strap. Bulk approval should be based on the assembled strap rather than the dimensions of loose metal pieces alone.
Quality-control checkpoints
Incoming inspection can confirm the correct model, complete piece count, absence of obvious deformation and the ordered finish. Pre-production sampling should then check tape routing, movement, component orientation and the appearance of the finished strap. This keeps quality control focused on observable production fit rather than unsupported technical performance claims.
Preventing size and set mix-ups
Hardware in 18 mm, 20 mm and 22 mm classes can appear similar at a glance. Standard and wide-body sliders may also be confused when only finish color is considered. Use size, product code and set type together on bin labels and work orders. Do not release material to production based on appearance alone.
First-piece inspection
Compare the first completed straps in a production run with the approved reference sample. Look for tape twisting, unwanted hardware rotation, excessive play and restricted adjustment. If a difference appears, review the tape and sewing process as well as the metal components before continuing the run. The strap system should be evaluated as a whole.
Inventory and consumption planning
The minimum order is 500 sets. Actual purchasing quantity should account for set consumption per garment, sampling requirements, the company’s own quality-reject history and any internal safety stock. Store quantity tiers are commercial price levels and should not be interpreted as a recommended production-loss allowance.
Repeat-order traceability
Use product code, 20 mm / 0.79 in size, wide-body designation and set type together on repeat orders. A generic “20 mm bra hardware set” description is not specific enough when multiple variants exist. Matching terminology across technical packs and purchase orders helps preserve the previously approved combination.
Short selection guide for production teams
First confirm the strap width and construction, then confirm whether the design requires a slider-and-ring system without a hook. The wider slider body should be an intentional design choice and not an accidental substitution. Finish the process by building a complete sample with the actual tape before approving bulk production.
Production planning by set
Commercial set quantity should be separated from physical component consumption. Sampling, first-piece approval and internal quality-reject allowances can be planned independently. This gives sourcing and production teams a clearer view of how many coordinated hardware sets are actually required.
Clear naming on bins and work orders
A generic “20 mm set” label is not specific enough. Standard-body or wide-body designation, two-piece or three-piece structure and product code should appear together. Using the same wording in purchasing and production records reduces substitution errors.
When re-sampling is needed
Build a quick new sample when strap supplier, thickness, elasticity, surface texture, fold construction or sewing method changes. Nominal 20 mm / 0.79 in width can remain unchanged while actual hardware behavior changes.
Component direction and assembly order
Correct components can still fail to behave as intended when installed in the wrong direction or sequence. Keep an approved sample available on the line so operators can visually confirm strap routing and component orientation.
Repeat-order traceability
Keep product code, set type, nominal size, material and finish together in the technical record. An approved sample or production image can support that record and reduce the chance of later substituting a visually similar but different set.
Choosing the wide-body set on e-buttons
The wide-body two-piece set is a distinct 20 mm / 0.79 in variant for designs that intentionally use a fuller visible slider body. It should not be confused with the standard two-piece set. Keep “Wide-Body,” the product code and the two-piece designation together in purchasing records.
Opening sets and counting components
Each opened set contains one wide-body slider and one ring. Warehouse counting should distinguish commercial set quantity from individual component quantity. Opened parts should not be mixed with nearby sizes or standard-body components.
