20 mm / 0.79 in Zamak Bra Strap Slider PIR710020Z

20 mm / 0.79 in Zamak Bra Strap Slider is part of the 20 mm / 0.79 in Zamak bra-hardware family used for wider lingerie and swimwear straps. It is intended to adjust usable strap length. For production approval, the metal component should be reviewed together with the real elastic or strap tape, seam placement and the other connection points in the finished assembly.

Understanding the 20 mm / 0.79 in size class

The nominal size describes the strap-width class, but production behavior is also affected by tape thickness, weave density, edge firmness, elasticity and folded construction. Two tapes with the same nominal width can move differently through the same metal component. A physical sample is therefore part of responsible approval.

How the adjustment function works

The strap changes direction through the slider body, creating the geometry needed for an adjustable usable length. A seam placed too close to the slider can restrict movement; excessive free tape can change the intended adjustment range. Sampling should therefore evaluate routing, fold allowance, stitch position and movement together.

Standard 20 mm / 0.79 in slider

This product is the standard-body slider in the 20 mm family. A wider-body version also exists in the same strap class. The two should remain separate in technical documentation and repeat orders because body geometry and visual proportion are different even when nominal strap width is the same.

Zamak construction

The product is classified as Zamak hardware. That identifies the material family; it does not by itself establish coating life, corrosion resistance, wash performance or chemical resistance. If those properties are important for a specific garment program, they should be confirmed through separate quality documentation or testing.

Use in lingerie and swimwear straps

The 20 mm / 0.79 in class can be used in bras, bralettes, swimwear and bikini strap constructions where the design calls for wider hardware. Final suitability depends on the complete strap system, not the metal piece alone. Tape routing, fold allowance, seam direction and neighboring components should all be reviewed together.

Why nominal width is not enough

A 20 mm tape can be dense and firm, soft and compressible, or highly elastic. These differences affect routing, movement and how the hardware sits on the finished strap. If the tape binds, folds, rotates unexpectedly or feels excessively loose, review the component-tape combination before bulk production.

Sourcing and warehouse control

Do not store the 20 mm / 0.79 in component under a generic label with nearby 18 mm or 22 mm sizes. A label that includes both product type and nominal size reduces picking errors. Repeat orders should use the complete hardware description rather than a general “bra strap part” name.

Using one component across a collection

The same approved hardware can be shared across multiple colors or garment sizes when the strap construction remains technically equivalent. If tape supplier, thickness or elasticity changes, build a short verification sample instead of assuming the previous approval automatically carries over.

Sewing and assembly considerations

Keep nearby seams far enough from the hardware to preserve the intended movement and strap path. Fold allowance and free-tape length should follow the approved sample. When several similar sizes are used in the same facility, a physical reference sample can help operators identify the correct component and orientation.

Finished-garment checks

After assembly, inspect the strap for twisting, bunching, unwanted hardware rotation and restricted movement. Review the complete strap system rather than only the metal piece. First production pieces can be compared with the approved sample before the run continues.

Finish options

The family uses Nickel, Black Nickel and Gold finish options. A listed finish with zero option stock should not be interpreted as immediately available inventory. Check the selected option quantity when planning production or repeat orders.

Minimum order and quantity pricing

The minimum order is 500 pieces. Quantity-based group pricing is defined for higher order tiers. This description does not publish or explain the commercial pricing policy; the current price shown by the system at order time is the applicable reference.

Avoiding selection errors

Do not confuse 20 mm / 0.79 in hardware with nearby 18 mm or 22 mm sizes, a standard slider with a wide-body slider, or the function of a ring or hook with an adjustment slider. Checking product name, code and approved sample together reduces sourcing and warehouse errors.

Repeat-order traceability

For repeat purchasing, retain product code, hardware type, nominal size and Zamak material in the order record. A generic description such as “20 mm metal part” is not specific enough. The same naming should appear in the technical pack and warehouse label.

Quality-control approach

Receiving inspection can confirm the correct hardware type, overall form and the absence of obvious deformation. Functional approval should then use the actual production tape. No unsupported surface-life or service-life promise is included here; program-specific quality requirements should be documented separately.

Selection summary for production teams

20 mm / 0.79 in Zamak Bra Strap Slider should be approved as part of a complete 20 mm / 0.79 in strap construction. Correct size class, correct hardware function and the approved assembly method need to align. Evaluating the item with the other 20 mm family components on e-buttons makes coordinated sourcing easier.

Matching parts within the 20 mm / 0.79 in family

A 20 mm strap system may use a slider, ring, hook and alternate body styles together, but nominal size alone does not make every component an automatic match. The technical pack should identify which pieces belong in the same construction. During sampling, check orientation, strap routing and the interaction between neighboring hardware rather than approving each metal piece in isolation.

Preparing materials before bulk production

Before the line starts, place the approved hardware, strap tape and sewing reference together as one preparation set. This is especially useful when nearby sizes are stocked in the same facility. Labels should show product code, size class and hardware type. Similar finishes should never be used as the only way to distinguish 18 mm, 20 mm and 22 mm components.

How tape construction changes behavior

Two tapes marked 20 mm / 0.79 in can behave differently. One may be dense and firm while another is soft, compressible or highly elastic. That difference changes how the hardware sits, moves and presents on the finished strap. If the tape supplier or weave changes, build a short verification sample even when the nominal width stays the same.

Finish selection in product development

Nickel, Black Nickel and Gold finishes create different visual relationships with the strap and garment fabric. A finish can appear subtle on one colorway and highly visible on another. Review the hardware on the actual textile rather than judging the metal piece alone. Option stock should also be checked before production quantities are committed.

First-piece production inspection

Compare the first completed straps with the approved sample before continuing the run. Review hardware orientation, tape twisting, stitch distance and overall symmetry. A correct metal component can still perform poorly if the tape was routed in the wrong direction or the seam was placed too close to the hardware.

Warehouse separation

Store visually similar 18 mm, 20 mm and 22 mm components in clearly separated bins. A complete label should include size, hardware type and product code. This reduces picking mistakes and makes repeat orders easier because the approved item can be traced by more than appearance or finish color.

Re-sampling after a component change

Changing from a standard body to a wider body, from one ring geometry to another, or from one hook connection to a different construction may require a new sample even when nominal size remains 20 mm / 0.79 in. Geometry affects routing, seam placement and the visual balance of the finished strap.

Planning order quantities

The 500-piece minimum is the base purchasing quantity. Actual production planning should separately account for component consumption per garment, sampling use, quality rejects and any internal safety stock. The quantity tiers shown by the store are commercial order levels, not a recommended production-loss allowance.
