20 mm / 0.79 in Zamak Bra Strap Slider and Ring 2-Piece Set PIR700020Z

20 mm / 0.79 in Zamak 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 standard 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 standard 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.

Standard-body 20 mm / 0.79 in set

This set uses the standard-body slider. A wide-body alternative exists in the same nominal strap class, so a generic “20 mm set” label is not specific enough for repeat production. Keep standard and wide-body versions under distinct product codes to preserve the approved construction.

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, standard-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. Keep the standard slider distinct from the wide-body alternative. Finish the process by building a complete sample with the actual tape before approving bulk production.

Production planning by set rather than loose pieces

Set purchasing should be translated into actual consumption per finished garment. A collection may use one set per strap assembly, two sets per garment or a different combination depending on construction. Sampling, first-piece approval and the company’s own quality-reject allowance should be considered separately. This prevents a commercial set count from being confused with the number of individual metal pieces required on the line.

Clear naming on bins and work orders

A generic “20 mm set” label is not specific enough when standard-body, wide-body, two-piece and three-piece versions exist. Bin labels and work orders should show set type and product code together. Using the same description in purchasing, warehouse and sewing documentation keeps every team aligned on the approved hardware combination.

When a new sample is required

Re-sample whenever strap supplier, thickness, elasticity or surface texture changes, even if nominal width remains 20 mm / 0.79 in. The metal pieces can move differently on a new tape. A change in seam type, fold construction or attachment method can also justify a quick verification sample before bulk production continues.

Component orientation and assembly sequence

Correct components can still produce a poor strap if they are installed in the wrong orientation or order. Keep an approved physical reference available on the line so operators can compare tape routing and component direction directly. This is more reliable than identifying small hardware only from memory.

Strengthening repeat-order traceability

For future seasons, retain product code, set type, nominal size, material and finish in the technical record. An approved physical sample or production photograph can support that record. This makes it less likely that a visually similar but technically different set is substituted during a later purchase.
