براغي ضبط #1-72 × 3/16" بنقطة كوب مخددة | فولاذ سبائكي (100 / عبوة)

I needed a tiny socket drive for a delicate adjustment on a piece of equipment, and these #1-72 screws fit perfectly with their hex socket. The knurled cup point gripped firmly without stripping, and the alloy steel feels solid. Worked exactly as intended for my small project.

These little alloy steel screws have some real bite with that knurled cup point, they held my miniature fixture rock solid through a full machining pass. Bought the 100-pack for the price of a few at the hardware store, and the hex socket makes seating them in tight spots a breeze.

The hex socket drive made tightening these in a tight spot so much easier than using a standard screwdriver. They fit perfectly into the countersunk holes I was working on.
