براغي ذات رأس أسطواني M24-3 × 110 مم | محرك سداسي | ملولبة جزئيًا | فئة 12.9 سبائك فولاذ أكسيد أسود حراري (10/عبوة)

The hex socket drive made torquing these into my jig frame effortless, and the partially threaded design gave me just the right grip depth. They felt solid during assembly, no stripping or wobble.

The hex socket drive on these M24-3 screws grips the Allen key perfectly—no slipping even under heavy torque. Installed a few into a jig frame this morning and the Class 12.9 alloy steel feels rock solid for the price. The black oxide finish is a nice bonus for corrosion resistance too.

The partial threading on these screws was exactly what I needed for a jig assembly, and the black oxide finish hasn't chipped at all during tightening. They feel incredibly sturdy, definitely up to heavy use in tooling work.
