براغي رأس أسطواني 1/4-20 × 2-1/4 بوصة | رأس مسطح مع محرك سداسي | فولاذ سبائكي (400/عبوة)

Used a handful for a tooling fixture and the flat head sits perfectly flush. The hex drive grabs cleanly without stripping, and they have a solid feel in the hand.

Bought these for a jig I’m building and the hex socket drive made seating them in tight spots a breeze—no stripping even with a worn bit. The alloy steel feels solid, and at 400 per pack, I’ve got enough for the next few projects without worrying about running out.

Installing these into a tooling fixture and the alloy steel feels noticeably tougher than standard hardware, no stripping issues so far. The hex drive fits my bits perfectly, which makes assembly quick. Exactly what I needed for precision work.
