براغي قفل مقبس HOLO-KROME 06026 7/8-9 X 7/16" | محرك مقبس سداسي | فولاذ سبائكي (25 / عبوة)

The through hex socket made installation a breeze with just an Allen wrench, and these feel much more secure than the standard set screws I've used before. Definitely tightened up my assembly without any slippage.

I needed some extra locking power on a heavy-duty setup, and these jam screws threaded perfectly over the set screw to hold everything tight. The alloy steel feels solid and the hex drive seated cleanly without any wobble.

The through hex socket makes these jam screws incredibly easy to drive and lock down firmly, saving me a lot of frustration during assembly. They fit perfectly in my tapped holes and the alloy steel feels solid and well-made.
