12 mm (0.47 in) 54-System Domed Metal Snap – 250 Sets SB 1877

Domed Metal Snaps for Textile Closures

A dome-shaped cap gives a garment closure a visible metal detail while the matching 54-system socket, stud and post make the fastening work. This is a sheet-metal, four-piece snap family, not an all-plastic garment fastener. Jacket fronts, coats, pockets and suitably reinforced bag details are typical starting points for prototype evaluation. The precise mounting choice depends on the actual layers and the profile of the cap.

Nominal Cap Size Versus Component Measurements

The sale name uses 12 mm (0.47 in) and 20 ligne. The detailed specification lists a 12.2 mm (0.48 in) cap, 11.8 mm (0.46 in) socket, 9.8 mm (0.39 in) stud and 10 mm (0.39 in) post. Do not treat those four readings as interchangeable diameters. A 12 mm (0.47 in) cap does not imply punching the same-size opening through the fabric. Setting pressure and any material preparation should follow the actual die and cloth sample.

Packing Calculation: 250 Closures, 1,000 Pieces

One wholesale pack contains 250 domed caps, 250 sockets, 250 studs and 250 posts. Together they make 250 complete snap sets, not 1,000 finished closures. An incorrectly counted order can leave production short of one component even when the total number of loose pieces seems high. A setting die or press is not included in the pack.

Metal Grade and Coordinated Finishes

The verified base material is sheet metal. Nickel, Gunmetal (Black Nickel) and Gold describe available visible finishes. A dark black-nickel finish is not a different alloy or proof of stainless-steel corrosion performance. Color coordination should be checked against the other fasteners, zipper pulls and trims that appear on the same garment. Surface appearance may shift under photographic lighting or between production lots.

Choosing a Press and Matching Setting Die

The catalog identifies the KLP0056 12.5 mm 54-system setting die in its tool recommendations. Because this is a domed cap, support at the upper die seat matters: a generic flat or plastic-cap die may mark or deform the visible face. Verify compatibility with the press fitting and the actual sample before production. A hand press or suitable impact press may be part of the installation workflow, but the exact setup must be confirmed.

Sample Testing Before the Line Starts

Prepare the real garment fabric with its interfacing, lining or reinforced seam. Install the four components in the intended orientation, then check for distortion, cap dents, uneven snap engagement and loose posts. For children's garments, performance and small-parts requirements need their own market-specific assessment. This listing does not claim an independently verified pull-test certificate.

Ordering and Branded Components

The ordering minimum is 250 complete sets. Recorded quantity pricing steps are 1,000, 5,000 and 10,000 sets. Branded caps can be discussed by supplying an artwork reference, finish sample, target quantity and a representative garment construction. Approval of the sample should include both the cap appearance and the mechanical closure result.
