براغي مقبس مسطحة الرأس 1/4-28 × 1-1/2 بوصة | فولاذ سبائكي (100/عبوة)

The hex socket drive grabbed my Allen key perfectly even in a cramped spot where I couldn't get a wrench in. All 100 screws were cleanly threaded with no burrs out of the bag, which is exactly what I hoped for.

I needed some high-torque fasteners for a jig I'm building, and the hex socket drive on these let me really cinch them down without stripping. The flat point tip also helped them sit flush in a counterbore. Solid 100-pack for the price.

Installing these in a tight bracket was simple since the hex socket grabs the wrench securely. The 1 1/2-inch length gave me enough bite into the steel, and the flat point holds firmly without marring the surface.
