12.5 mm / 0.49 in Optic White Plastic Cap 54 System Snap Fasteners, 100 Sets ERC00125PLOBeyaz

12.5 mm / 0.49 in Optic White Plastic Cap Snap Fasteners are made for lightweight and medium-weight textile products that need a neat, practical closure without a heavy metal appearance. Each complete snap set includes one optic white plastic cap and three stainless silver lower components: the socket, stud, and post.

The clean white cap works especially well on babywear, children’s clothing, bodysuits, rompers, shirts, medical uniforms, and spring-weight garments. It provides a tidy finish on pale fabrics while remaining visible enough to work as a deliberate contrast detail on darker materials.

Suitable Uses

This 12.5 mm / 0.49 in size is a suitable option for bodysuits, baby clothing, children’s garments, shirts, lightweight uniforms, medical apparel, sleepwear, and similar textile products. It is designed for places where the snap should close securely without overpowering the fabric or making the closure area look bulky.

For heavier outerwear, thick multilayer fabrics, or points exposed to a higher pulling force, evaluate the actual material thickness and garment construction before choosing the snap size. A larger snap or another fastening type may be more appropriate when a stronger closure is required.

54 System S-Spring Construction

This item uses a 54 System S-spring snap construction. A complete set is formed by four parts: the plastic cap, socket, stud, and post. The closing action depends on the correct alignment of the lower components, so parts from a different system should not be mixed into the same installation.

For related colors and different cap options, browse the snap fastener collection and compare the finish against the garment fabric before production begins.

Material and Finish

The visible cap is optic white plastic. The three working lower components have a stainless silver-metal construction. This combination is useful when the design calls for a cleaner, softer surface than a fully metal snap button.

The lower components are intended for standard garment washing conditions. For garments that will be exposed repeatedly to saltwater, marine environments, or highly aggressive chemicals, test the finished garment in its real use conditions before proceeding with full production.

Installation Guidance

Use the matching 12.5 mm / 0.49 in plastic cap 54 System snap setting die to install this product. The matching die helps support the cap, align the lower components, and reduce the chance of cap deformation during pressing.

Compatible installation can be carried out with hand-setting equipment, a hand press, an impact press, an electric machine, or a pneumatic machine. For workshop use, the M0099 hand press fastening machine can be used with the correct die and connection type.

Always make a test installation before production. Check cap alignment, holding strength, closure feel, and the appearance of the reverse side. On thin, stretch, or loosely woven fabrics, a suitable backing or reinforcement layer may help keep the installation area stable.

Pack Quantity

This product is supplied as 100 complete snap fastener sets. Each set includes one plastic cap and three lower metal components. The pack size is suitable for sampling, small-batch apparel production, alteration work, and manufacturers who need the same closure across repeated styles.
