Most "quick release" thumb screws are garbage. JeepBolts has been manufacturing our own screws for our site since 1997.

We have a ton of customers that come to us because the zinc post snapped off the head. You can see the head tops have a "rough" appearance and the threaded post is coated the entire way down. Also, we throw in neoprene washers to help prevent them from scratching the top part of your hardtop.
These bolts will fit 1978-2023 CJ, YJ, TJ, JK, and JL Wranglers
