100pcs Cone Spikes Screwback Studs DIY Craft Cool Rivets Punk Stud Coincal 7x10mm 1/4"*3/8" Silver

These were exactly what we needed. Teen girl used them to decorate thick leather jacket and leather belts for a punk rock costume. They worked exactly as described. We used all of them and none seemed to be defective (maybe one or two were a little harder to screw on straight, taking a couple of tries, but that is out of 100 items). They did not unscrew or fall out during party activities, riding in car, or trick/treating. The size is true to expectation. They feel smaller in your hand, but look the correct size when installed to fabric. They are hard to hold on to, as they are slippery cone shaped, so large flat surface recommended. We used leather awl to poke holes and then held the screw side of the spike with a screwdriver, applying pressure to hold, and screwed spike onto the poking out end. It is fidgety due to the small size and slippery-ness, but that is not a product defect, just the reality! We also purchased larger spikes and ended up using them to help widen the awl-poked hole. That helped some.Great product, as described, and seems to be very good quality for the price.

Very strong, I prefer the screwback to other ways of securing studs. Nice color, nice weight to them. I bought these for jeans -- and I've gotta say, 100 pieces sounds like a lot more than it is. Should have known, but I just didn't think about it. If you're doing any large project like a bag or jacket, maybe get 200-300. Very nice overall, would probably buy again.

Update September 18th . Purchased them in black and white and I adore them! The pkg included a tool this time.I love spikes. I only gave four stars because I had to put glue inside the spike to prevent it from unscrewing. However, I am sure it's because they were used on shoes and are constantly moving...not sure. I plan to buy them in silver.

I bought these for a jacket. I was SUPER excited, going to my First Lady Gaga concert and all. I used a tiny screwdriver to twist them in, and an awl to poke the hole in, which I would do all the way through. Every piece stayed in perfect, always secure. I got a lot of compliments on my jacket, so it's safe to say if I had the chance to make something again, I would!

I ordered these for my oldest (14) and my cousin (18) who are into goth and making their clothing their own. Might update after they use the product to give it and higher or lower rating but so far they are super excited and want me to order more 😄😃

The screw back spike studs are so easy to attach to the bracelets and collars that I custom make with leather. With a wide range of colors I get so many compliments on my creations with these. I have had no issues with these. I would re-purchase.

Great product, Great price. Wish I could have gotten a smaller package. Used them to decorate puppy collar.

I love the spikes! They look great on my jacket & my vest. Anyways, the tool I got makes no sense. I've done just fine without it though.I'm short like 12 screws for my spikes. How can I get the rest?I will definitely order again soon!
