HOLO-KROME 07028 1-14 × 1/2 بوصة براغي مقبس سداسية | محرك مقبس سداسي | فولاذ سبائكي (25 / عبوة)

The hex socket cut is clean and precise, so my Allen wrench grabs it without slipping. These jam screws lock tight on a tapped hole—exactly what I needed for a stubborn spring.

I needed these for a jig I was building, and the hex socket drove cleanly into the tapped hole without any wobble. The alloy steel feels sturdy enough for repeated adjustments, and the 25-pack should last me a good while.

The through hex socket makes them easy to drive even in tight spots, and the alloy steel feels solid. They did the job of locking my set screw in place without any stripping. Just wish the package had a few more for the price.
