12 mm / 0.47 in Nickel-Free Zamak Bra Strap Adjuster and Ring Set, 500 Pairs PBT0007PROMO

This 12 mm / 0.47 in nickel-free zamak bra strap adjuster and ring set is a two-piece metal hardware solution for adjustable shoulder straps. It includes a strap slider for length adjustment and a matching ring for strap connection. Together, these components are commonly used in bras, bralettes, lingerie, bikini tops, swimwear, sports bras, camisoles, and other products built with narrow adjustable straps.

The slider controls the strap length, while the ring provides a stable point for joining the strap to the garment body, back band, hook section, or related sewn construction. When both parts share the same finish and proportions, the finished garment looks more intentional and the strap system is easier for the wearer to adjust.

Designed for 12 mm / 0.47 in Strap Width

This set is intended for 12 mm / 0.47 in elastic, narrow webbing, or compatible strap materials. The adjuster and ring are sized for that strap width, so the actual strap should be checked before production.

Not every 12 mm strap behaves the same way. Elastic thickness, weave density, edge finish, stretch recovery, and surface texture can affect how smoothly the strap moves through the slider. Make a sample with the actual strap before starting a larger run, especially when using thick elastic, coated webbing, or layered strap construction.

What Is Included in the Pack?

The package includes 500 strap adjusters and 500 matching rings. This provides 500 coordinated pairs, or 1,000 individual metal components in total.

This product is not a complete three-piece bra hardware set. It includes the slider and ring only; it does not include a bra hook. When your product needs a hook, choose a compatible hook separately or compare it with a 12 mm three-piece set that includes a slider, ring, and hook.

Product Measurements

The strap-use inner width is 12 mm / 0.47 in. The slider’s stated outside dimensions are 13.5 mm × 15 mm, approximately 0.53 in × 0.59 in. The matching ring has a 12 mm / 0.47 in inner diameter.

These compact dimensions work well for lingerie and other narrow-strap products where a larger buckle may feel too heavy or dominate the overall design. Before finalizing a pattern, check strap width, stitching allowance, strap fold thickness, and the position of the ring on the finished garment.

Zamak Metal and Nickel-Free Finish

The components are made from zamak metal and finished in a nickel-free appearance. The silver-tone finish can coordinate with other visible garment hardware such as zipper pulls, bra hooks, rings, sliders, labels, and decorative metal details.

For products exposed to frequent laundering, sweat, saltwater, chlorine, sunscreen, or prolonged skin contact, test the finished accessory under the actual intended use and care conditions. Final product performance depends on the complete garment construction, strap material, cleaning process, and surrounding accessories.

How to Attach the Slider and Ring

This product is installed by threading the strap through the slider and ring, then sewing the required strap ends into the garment construction. It is not a press-on or die-set product, so no setting tool is required.

Keep the strap flat during assembly. A twisted strap can make the adjuster difficult to use and may create an uncomfortable fit. Reinforce the sewn strap ends according to the garment’s expected use, especially around the ring connection and back-band area where pulling force can be higher.

Applications in Lingerie and Swimwear

This 12 mm set works well in bras, bralettes, lingerie tops, camisoles, swimwear tops, bikini designs, and selected sportswear with narrow adjustable straps. It is especially suitable for designs where the visible metal hardware should look clean and refined instead of bulky.

For swimwear, test the finished product after exposure to the expected washing and wear conditions. Saltwater, chlorine, heat, sunscreen, and repeated stretch can affect the full garment system, including the elastic, stitching, metal parts, and fabric.

If your design needs a hook in addition to the slider and ring, compare the 12 mm metal nylon-coated three-piece set PIR720012. For a standard 12 mm slider-and-ring alternative outside this promotional package, compare the PBT0007 series in the same category.

Custom Production for Brands

Bra strap sliders and rings can be developed with custom strap widths, finish colors, shapes, surface details, logo applications, and brand-specific hardware direction. This is useful for private-label lingerie, swimwear, sportswear, and fashion collections that need a consistent hardware language across the garment.
