Customer Reviews (4.8 / 5 · 5 reviews)

Stella ★★★★★

Used these to mount a heavy-duty jig on my mill table, and the class 8.8 alloy steel handles the torque without any sign of stripping. The hex socket drive is a breeze to tighten with a standard Allen key, and the 80mm length was perfect for the thick plate.

Madison C. ★★★★★

The black oxide finish on these M20 screws looks great and seems durable, and the hex socket drive made installation a breeze. Perfect for securing heavy machine guards.

Ryan ★★★★★

Used these M20 cap screws for a precision tooling fixture, and the hex socket drive made tightening them in tight spots much easier than allen bolts. The partial threading gave just enough grip without needing a full thread everywhere. Solid feel for the price.
