20 mm / 0.79 in Zamak Bra Strap Ring PIR720020Z

20 mm / 0.79 in Zamak Bra Strap Ring is a Zamak bra strap ring for the 20 mm / 0.79 in strap class. Its primary function is to create a strap connection and direction-change point. Selection should be based on the actual production tape rather than nominal width alone, because thickness, stretch, folded construction and surface friction can change how the hardware behaves in the finished strap.

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.

Role of the ring in a strap system

A ring does not adjust strap length. It provides a connection and direction-change point between strap sections. The actual fit depends on tape width, folded thickness and the angle at which the strap enters and leaves the ring. Those factors should be checked on a complete sample.

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.

How to record it in a technical pack

Keep product type, 20 mm / 0.79 in size class and Zamak material together in the bill of materials. If the same collection uses another size or body style, retain the product code as well. Consistent naming across purchasing, warehouse and production records helps the approved component remain traceable.

Sample-approval sequence

Start with the actual production tape, route or connect it according to the intended construction, complete the fold and stitch work, and then inspect the finished strap. Checking the metal component by itself does not confirm final production fit.

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 Ring 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-Dugme makes coordinated sourcing easier.

Thinking in complete 20 mm / 0.79 in systems

A strap assembly may combine a slider, ring, hook and alternate body styles from the same nominal size family. Matching width does not mean every component performs the same function. The bill of materials should state the role of each piece so production teams can distinguish adjustment, connection and hook functions during assembly.

Checking size with the real production tape

The 20 mm / 0.79 in label describes nominal width, but actual fit also depends on tape thickness and the volume created after folding. Elastic stretch and surface texture can change movement through or around metal hardware. A ruler check is useful at receiving, but functional approval should use the real tape and intended seam construction.

Keeping assembly orientation consistent

Correct hardware can still create a poor result if it is reversed or if the tape follows the wrong path. Keep an approved physical sample or clear production image available at the line. Operators should compare orientation and routing against that reference rather than relying only on memory, especially when several similar components are used in one facility.

Coordinating finish with the garment

Nickel, Black Nickel and Gold are visual finish options within the same product family. Review the selected finish next to the actual strap and garment fabric because contrast can change the perceived prominence of the metal part. A finish listed with zero option stock should not be treated as immediately available without checking current inventory.

Basic incoming inspection

Receiving checks can confirm product model, nominal size, quantity and the absence of obvious deformation. A small sample can then be tested with the approved production tape. This approach focuses on observable production suitability rather than making unsupported claims about coating life, corrosion resistance or mechanical load performance.

Repeat-order identification

For repeat sourcing, use product code, 20 mm / 0.79 in size class and hardware type together. A photograph or generic product label may not be sufficient when nearby sizes and similar shapes exist in the catalog. Consistent naming between the technical pack and purchase order improves traceability to the previously approved component.

From first-piece approval to bulk production

Compare the first completed straps from a production run with the approved sample. Look for tape twisting, excess play at connection points, unwanted hardware rotation or seams that restrict movement. If a difference appears, review tape and sewing conditions as well as the metal component before deciding on corrective action.

Sharing hardware across sizes and styles

The same 20 mm / 0.79 in component can sometimes be used across multiple garment sizes or colorways. That should only be assumed when the strap construction is technically equivalent. If strap length, attachment point or sewing method changes, perform a quick verification rather than extending one sample approval to every style automatically.

Inventory planning

The minimum order is 500 pieces, but purchasing quantity should reflect the actual production plan. Component consumption per garment, sampling needs and the company’s own quality-reject history can be included in planning. The store’s quantity tiers are commercial order levels and should not be interpreted as a production-loss standard.

Preventing mix-ups inside the 20 mm range

Keep 18 mm, 20 mm and 22 mm hardware in separately labeled bins. Standard-body and wide-body sliders should also remain distinct records. Labels that include size and product code help both warehouse and production teams avoid selecting a visually similar but technically different component.
