براغي مجموعة مخروطية 3/4-10 × 1-3/4 بوصة | فولاذ سبائكي (25/عبوة)

The hex socket drive really lets you crank these down in tight spots without stripping—I had to adjust one a few times and the cone point bit in clean each time. Alloy steel feels solid, and the 1-3/4 length gave me plenty of thread engagement for a heavy fixture.

Installed these to lock a pulley onto a keyless shaft, and the hex drive made torquing them down in a tight spot straightforward. The alloy steel feels solid and the cone point grabbed exactly where I aimed.

The hex socket drive made torquing these down in a cramped alignment fixture a breeze, and the cone point seated perfectly into the dimple. The alloy steel feels solid enough to trust for repeated adjustments without stripping. Pack of 25 should last me a good while.
