براغي ضبط ذات رأس كروي من النايلون 1/4-20 × 1 بوصة | فولاذ سبائكي (100/عبوة)

Installed these in a jig for workholding and the nylon cup grips parts nicely without marring. The hex socket drive made tightening into the threaded holes effortless even in a tight spot.

Was a bit skeptical about nylon cup point screws holding up, but these alloy steel ones are solid. The hex drive let me really torque them down in a tight spot without stripping.

The hex socket drive made tightening these in a cramped spot on my machine way easier than I expected, and the nylon pellets seat firmly without stripping the threads underneath. Pack of 100 means I've got spares for the next rebuild, which is a relief.
