HOLO-KROME 07014 براغي تجويف سداسي 5/16-24 × 5/32 بوصة | محرك تجويف سداسي | فولاذ سبائكي (100 / عبوة)

I needed these for a tight spot where a standard nut wouldn't fit, and the through hex socket makes installation quick with just an Allen key. The alloy steel feels really sturdy, and the 100-pack means I have plenty spares for future jobs.

The hex socket drive on these jam screws made setting them deep into a tapped hole surprisingly easy. Fit perfectly to lock down a vibration-prone adjustment bolt on my milling machine.

That little hex socket through the center makes seating them flush so much easier than a regular grub screw, and the 100-count pack means I’ve got spares for days. They threaded into my tapped holes cleanly without any binding, which is all I really ask for.
