Customer Reviews (4.6 / 5 · 5 reviews)

Lily I. ★★★★★

The nylon pellet in these flat heads locks them in place far better than any thread locker I've tried, so they're staying put in my jig even under vibration. All hundred came fully threaded and the black oxide finish looks sharp while sliding into tight holes without binding.

Miles V. ★★★★★

I needed a hundred for a tooling fixture and these came fully threaded with the nylon pellet already locked in, which saved me a step. The hex socket drive seated cleanly without any stripping, and the batch was consistent in length. Solid value for precision work.

George ★★★★★

Used a few of these to mount a jig fixture to my mill table, and the flat head sits perfectly flush. The black oxide finish and nylon pellet held tight even under vibration, and the whole pack was consistent in thread quality.
