Snaps are a professional fastening system; they replace the need for hook & loop closures on nappies. They also come in handy for many other things around the home; from clothing to duvet covers, handtowels to sleeping bags.



To attach the professional grade Polycetal Resin Snaps sold here, you need a piece of equipment called a Snap Press. You do require a snap press (or press of some kind) as applying snaps requires an exact amount of pressure to apply them properly to your item, so simply whacking a die set with a hammer will not work as you will not be able to consistently apply the required pressure. All professional snap press machines can be calibrated so snapping becomes a breeze with the amount of pressure applied restricted to the exact amount necessary.

2. DIE SET(s)

You use different sized Die Sets in your press to attach different sized Snaps, your die set needs to match the snaps you are wanting to apply as well as the press machine you wish to use.


Size 20 Snaps

This is our most commonly used size, perfect for nappies. Also great for lots of other uses. If in doubt, use a size 20. Size 20 Caps measure 12.4mm in diameter.

Size 16 Snaps

This size is great for mama pads or anything that doesn't need quite as strong of a grip as a size 20 snap. Size 16 Caps measure 10.7mm diameter.

Size 14 Snaps

These are more of a specialty item and are the smallest size available to us. Size 14 Caps measure 9.74mm diameter.



The cap is the most visible part of a snap, which is the dome that is visible on the outside of the garment. You need one cap per socket or stud. Some people mix cap colours with the socket or stud they are applying for visual effect.


The Socket is the female part of the snap that joins together with the male – you need one cap to apply one socket to a garment.


The Stud is the male part of the snap that joins together with the socket – you need one cap to apply one stud to a garment.


Most people use 3 sockets to 1 stud when making MCN’s, giving a 3-1 ratio. Socket & Cap sets are available because you usually use more sockets than studs on your nappies.


Our 100 full sets contain 100 sockets, 100 studs, and 200 caps (400 total pieces). A full set is enough to apply 100 complete sets of snaps. In other terms, 100 sockets & 100 studs.


Our 100 socket & cap sets contain 100 sockets, 100 caps (200 total pieces), enough to apply 100 sockets (female) only.
