10 mm / 0.39 in Zamak Bra Strap Ring is a single ring component for lingerie and swimwear strap systems. It is used at a strap connection or direction-change point and is not a length-adjustment slider. The nominal 10 mm / 0.39 in size identifies the hardware family; final suitability should still be checked with the actual production tape because tape thickness, stretch, edge construction and folded seams can change the fit.
What this ring does
The ring creates a stable connection point in bra, bralette, bikini, swimwear, bodysuit and similar strap constructions. It works together with other strap hardware but has a different function from a slider or hook. The ring guides the strap path; the slider changes strap length; the hook completes a detachable connection where the design requires one.
10 mm / 0.39 in size selection
Nominal width is only the first check. The real strap should pass through the ring without excessive binding or excessive free play. A tape that measures the same width can behave differently when it is thicker, softer, more elastic or folded near the connection point. Approve the ring on a completed sample before bulk production.
Zamak material
This product is classified as Zamak. Material, size and product type should be recorded separately in the purchasing and technical files. No unverified claims are made about plating life, corrosion resistance, wash durability or chemical resistance.
Package and minimum order
One sales unit contains one bra strap ring. The minimum order is 500 pieces. Package content and minimum order quantity should not be confused: 500 pieces means 500 individual rings.
Production checks
- Confirm the 10 mm / 0.39 in size family.
- Test the actual production strap through the ring.
- Check the folded strap thickness and seam position.
- Review the connection angle on a finished sample.
- Confirm the part is a ring, not a slider or hook.
- Keep the approved model code in the bill of materials.
When to use a ring instead of another component
Use the ring when the strap needs a connection or direction-change point. If the garment needs strap-length adjustment, a slider is also required. If the construction uses a detachable hook connection, add the matching hook or choose the appropriate set format. Products in the same size family are related but are not interchangeable by function.
Sampling before bulk production
Build one complete strap using the real production elastic or tape. Check whether the ring sits at the intended angle, whether the strap folds cleanly around the connection point and whether the nearby stitching leaves enough room for natural movement. If the tape supplier, tape lot or sewing method changes, repeat a short verification sample instead of assuming the previous approval still applies.
Warehouse and repeat-order control
Store rings, sliders, hooks and complete sets under separate model codes. Similar-looking parts can be mixed easily when only the nominal size is shown. Using model code, product type, 10 mm / 0.39 in size and Zamak material together on warehouse labels makes repeat ordering and production picking more reliable.
Frequently Asked Questions
What is included?
One 10 mm / 0.39 in bra strap ring.
What material is it?
Zamak.
Does the ring adjust strap length?
No. A slider performs the adjustment function; the ring is used as a connection or direction-change point.
What is the minimum order?
500 pieces.
Should it be tested with the actual strap?
Yes. Tape thickness, elasticity, folding and stitching can influence the final fit.
Can another 10 mm ring be substituted automatically?
No. The same nominal size does not guarantee identical geometry or production behavior. Sample approval is recommended when the model changes.
