Olivia ★★★★★

I've been using these for some jig assembly work and the hex socket drive makes tightening them in tight spots so much easier. The 600-count pack will last me for years of projects.

George H. ★★★★★

Got these for a precision jig I’m building, and the 316 stainless is exactly what I needed to avoid any rust worries in a humid shop. The hex socket drive seats perfectly with a 5/64 allen key, and the fully threaded length made alignment a breeze. Six hundred in the pack means I’m set for years.

Richard ★★★★☆

The hex drive on these #4-40 screws engages nicely without stripping, which is crucial for tight spaces on my jigs. I just wish the package had a few more extras for the price.
