120 Pcs Pin Locks Pin Backs Locking Clasp Bulk with Wrench, Aulufft Locking Pin Keepers Backs Locking Clasp Sliver 6 x 5 mm

Price compared many options here in Amazon and this was the best value for quantity and price. Quality is not comprised, as these are very sturdy and nicely made to do what theyre supposed to. A little tricky and slow at first, but you end up getting the hang of it and then can put them on much quicker. I found it easier to place the screw in each and just turn it a few threads, then put it on the back of your pin and tighten. The key is already having it partially threaded so your not trying to match it up once your on the pin if that makes sense. Ill definitely be getting these again once I finish putting this first set on my pins.

These work great but only gave 4 stars because they are a bit too short & the tip of the pin pokes through. Otherwise excellent product!

A little pricey but they hold

Ok, so Ill be honest I didnt measure my enamel pins. However, after seeing reviews of people having success it seemed like this was going to be a good fit. First off, the quality seems great, the piece that screws in fits perfectly and they give you like 8 allen wrenches which is great because everything is tiny sized. The major issue is that the length of these locking backs isnt long enough for any of the enamel pins I tried to put them on. I put the back on all the way on until it hit the little stopper piece is sticking up, and everytime the was just a little bit of the pin sticking out of the end. Which if youre putting this on clothing or in a bag is just begging for you to get cut. YES, you can slide the piece up a little bit and lock it into place a little higher to avoid the pins edge. But, when you do this you dont get a tight fight on whatever youre affixing it to. I tried it several times and ways on a bag and everytime it just kind of sagged. I was hoping these were going to be the end all for my pins, but Ill be looking elsewhere. Anyone want 100 of these things? I have no use for them, and dumb me waiting until April to try and put them on anything after ordering in November. In closing, if you got short pins, or dont care about sagging pins/getting stabbed then these backs are for you. Otherwise, get something longer.

My husband picked these out to keep his Disney pins in place on his bag while on our trip to Disneyland. Worked well. No pins fell off or were stolen this trip. He did mention that they are somewhat hard to get on/off even with the tool. But I guess that is what its all about.

I lose pin clasps all the time then I lose pin. This solves that issue without a whole lot of fuss.

Works well and great price.

Never buy another type of pin back again! These make sure that the item you pin on will not fall off!

What more can I say other than they do what they’re supposed to, and so far I haven’t had a problem with one yet. I bought them to replace the cheap fasteners on all my pins on my motorcycle vest, and I’ve used in the area of probably about 30 of them.

Shorter locks for less obstruction. Every unit perfectly machined and worked smoothly with the set screws. Exceptional quality control on these.
