Humane Restraint mods - What kind of rivets are these?
Trying to make a couple modifications to my humane restraint cuffs.
Can anyone tell me what kind of rivets these are? Beyond semi tubular I’m having trouble getting any specifics.

They look like leather belt rivets, but have a sort of washer to increase surface contact, giving them more strength. Maybe use a rivet long enough to go through the belt, buckle, and a rivet of proper size. It looks like they use a special gun to crimp. Would screw together type work? Use some loctite thread locking compound during assembly?

They are some type of single cap quick rivet, but beyond that I'm afraid I can't help you. I've never seen this particular system of quick rivet before. It looks like it's a 3 part system: a cap, a washer, an insert that is rammed into the inside of the cap stem from the opposite side to mushroom the stem over the washer and hold things in place.segufix wrote:Trying to make a couple modifications to my humane restraint cuffs.

It looks like this system to me: https://nl.aliexpress.com/item/10050033 ... 39a2cf7-10
secured with the metal form of (second figure, bottom right, used inverted): https://nl.aliexpress.com/item/10050023 ... 4841_4&s=p
So like: But with a smooth head as used on these snaps: https://www.lukeandjack.co.uk/colt-8-sn ... ther-55375

These rivets are known by several names.... hollow-end, semi-tubular, half-hollow, and brake lining rivets.
They have a truss head, the first part of the shaft is solid, and the second is hollow. A matched washer is applied over the free end of the rivet to capture the material being secured. The hollow portion is then rolled outward with a peening tool. Examples:

Sizing is quite important, as you'll only be able to roll the tip so far before it cracks or misshapes. On the Humane Restraints items, these are almost certainly stainless. Practice your peening a lot as stainless is unforgiving.

Thanks OA, learned something new today. Let's hope OP can use the knowledge too.

Re: Humane Restraint mods - What kind of rivets are these?
Yes, thank you, OA for offering your experience based advice here. Size is very key and definitely use stainless steel, due to perspiration and frequent cleaning of the restraint.
The screw on style might be easier and cheaper to work with though, no need for special tools, precise sizing, or the perfect touch.

Re: Humane Restraint mods - What kind of rivets are these?
Good info. Definitely need to practice and I don’t have a machine. In regards to the washers….I’ve also heard them called burrs. Is there any functional difference?
And in regards to washers/burrs, I’ve only seen them mentioned to be used with regular copper rivets (not semi-tubular)
Even though this is technically leatherwork, it’s a little different than fixing a broken grommet on a belt. Those HR belts are as sturdy and secure as they come and I’m hoping to get the same level of sturdiness as they come from the company
(Part of me wants to call HR and ask but I don’t think they would tell me since that’s kind of a “trade secret”) lol

Re: Humane Restraint mods - What kind of rivets are these?
Technically at least in (wooden) boat building for riveting the correct term for a flat round piece of metal with a hole in it used under the riveted head is a burr. There is also a cone shaped washer that acts a bit like a belleville washer/spring to create extra tension in the rivet, which is referred to as a rove. Washers are strictly speaking what you put under a screwed bolt/screw connection where something rotates relative to something else while applying the force but in the end it's basically just the exact same thing.segufix wrote:Good info.

Re: Humane Restraint mods - What kind of rivets are these?
While these rivets can be machine set, what you'll want is a clincher.... which you can definitely find as a tool (https://www.mcmaster.com/rivet-clincher ... ow-rivets/) and may also find as an anvil (although I cannot find one readily that isn't a setting machine anvil).segufix wrote:Definitely need to practice and I don’t have a machine.
Burr and washer are used interchangeably in this context, although burr is certainly historically accurate. I have always found it more convenient to use the term washer because everyone knows what that is.
You will definitely need them here, although you should be able to reuse the originals if you drill out the core with a bit of caution. You can use all manner of flattened or rolled rivets with rigid materials without a washer, but a flexible material like leather will require one to be secure.I’ve only seen them mentioned to be used with regular copper rivets (not semi-tubular)
