How do Swivel Clasps work?

Hi There,

I want to make chunky swivel clasps, but im struggling to figure out the inner workings and how it all looks/assembles.

Anyone got any advice or diagrams i can use to design my own similar to the attached photo?

Any help appreciated!

Hi! I use these all the time - preferred by millennials it seems - but I never considered making my own.

Here’s a photo of the ones I use. I’m wearing this on one of my bracelets - it’s the only clasps I use now that know about them.

This type of clasp is called a swivel-eye trigger snap. You could put a sister hook on a swivel and get the same effect without having to deal with the internal spring.
In your photo the swivel part of the clasp is exposed. I assume it is the spring closing that has you puzzled.

Exquisite! They are all absolutely stunning. The attention to details and skillful craftsmanship are evident in every single one. Well done!

wow these are so special!!

Here is a view of the inside of that exact clasp. Many clasps use that type of spring. You can make them yourself with stainless steel wire or buy them and design around their dimensions.

Hardihooder casts most of his designs. Making something like this in cad is relatively straightforward and you can find barebones models for free from a variety of 3D modeling sites.

This is a modified “sister hook clasp” to be spring loaded.
