براغي مقبس سداسي بنقطة نصف كلب 3/4-16 × 7/8 بوصة | فولاذ سبائكي (50/عبوة)

The hex socket drive worked perfectly in that tight spot behind the machine where a regular wrench couldn't fit. They seated cleanly and feel sturdy enough for repeated adjustments. Exactly what I needed for this application.

Used one of these to lock a sprocket hub onto a shaft and the half dog point really bites into the keyway groove, no slipping even at high torque. The hex socket drive makes threading them into tight spots a breeze with just an Allen key.

The hex socket drive made torquing these down in a cramped spot way easier than I expected with a regular wrench. All fifty pieces threaded clean with no burrs, and the half dog point seated exactly where I needed it.
