12.5 mm (0.49 in) Navy Blue Plastic-Cap Snap Buttons, 100 Sets ERC00125PLLaci

12.5 mm (0.49 in) Navy Blue Plastic-Cap Snap Buttons, 100 Sets ERC00125PLLaci

Navy is a flexible choice for makers working with blue fabrics, uniform pieces and clean everyday designs. These 12.5 mm (0.49 in) plastic-cap snap buttons feature a dark blue visible cover over a four-part 54 System closure. Each snap is built from a cap, a socket, a stud and a post; it is not a single push-on plastic fastener. The finish can help make a closure look intentional without changing the garment's style, provided the correct die and fabric preparation are used.

From schoolwear to small-batch sewing

On navy woven fabric, the plastic cap provides a subtle finishing detail. On ivory shirts or lighter accessories, the same blue can become a restrained accent. You can compare its appearance with denim, dark blue cotton and printed fabrics before deciding on a larger pack. Looking for a softer shade or a different size? View the plastic snap buttons collection. For other fastening mechanisms, the snap fastener category is a better starting point than choosing based on diameter alone.

Product specifications

Inside the pack

You receive 100 navy plastic caps, 100 sockets, 100 studs and 100 posts: 400 individual pieces that make 100 complete snap closures. The visible cap measures 12.5 mm (0.49 in), in the 20-ligne nominal cap class. Matching underparts are metal with a nickel-coloured finish. Setting dies and presses are not included; they are ordered independently.

The catalog identifies KLP00125PL54 as the appropriate plastic-cap 54 System setting die family. Confirm the cap seating shape and tool connection before ordering; not all 12.5 mm dies are interchangeable.

Make the first few fastenings count

Test a few snaps on the same layers used in your finished product. Check that the cap face is not marked, the fabric is not drawn in around the mounting point, and the socket engages consistently with the stud. If the assembly feels uneven, review pressure and die fit rather than simply forcing the snap harder. This small sample step also lets you judge how the navy tone reads against your garment under different lighting. For professional garment work, keep an approved sample alongside the material specification so future orders use the same cap and snap system.

For controlled installation of the navy cap, see the 12.5 mm / 0.49 in plastic-cap 54 System snap setting die, offered separately. Verify press-thread compatibility and test cap protection before batch production.

Frequently Asked Questions

What size are the caps?

12.5 mm (0.49 in) across the visible cap.

How many sets does one package provide?

100 complete snaps: 100 caps, 100 sockets, 100 studs and 100 posts.

Is the cap a complete snap by itself?

No. All four mating components are needed to make one closure.

Are the snaps entirely plastic?

No. The cap is plastic and the three lower components are metal.

Do I receive a matching press?

No. The setting die and any press or hand tool are separate purchases.

Can any 12.5 mm setting die be used?

Verify the 54 System profile, plastic cap seat and machine mounting first; matching diameter is not enough.

What if the cap becomes marked during setting?

Stop and recheck die shape, pressure and fabric support on a test piece before continuing.
