HOLO-KROME 07018 براغي مقبس 7/16-20 × 7/32 بوصة | محرك مقبس سداسي | فولاذ سبيكة (100 / عبوة)

The through hex socket makes these jam screws surprisingly easy to seat even in tight spots, and the alloy steel feels solid when torquing down. Pack of 100 means I won't be running out mid-project anytime soon.

The threads cut cleanly into the tapped hole without any binding, and the alloy steel feels solid for the price. I used these to lock down a stubborn adjustment screw on a milling fixture, and they held tight through the whole job.

The hex socket drive made installation straightforward with a standard Allen key, and the alloy steel feels sturdy enough for locking threaded assemblies. These fit precisely into a tapped hole without any wobble.
