Customer Reviews (4.8 / 5 · 5 reviews)

Ella U. ★★★★★

Drove these into a steel mounting block for a workshop press, and the hex socket grabbed perfectly without any cam-out. The 40mm length gave just enough bite for the heavy bracket, and all 100 screws had clean threads right out of the pack.

Charlotte ★★★★★

Used a full pack of these for a jig on a custom assembly line and every single one seated flush without any stripped threads. The 8.8 alloy steel feels solid and the low head profile made a huge difference in tight clearance spots. Exactly what I needed for precision tooling work.

Ella ★★★★★

The hex socket drive seated perfectly on my Allen key without any wobble, and all 100 pieces threaded cleanly into my fixture plates. Class 8.8 alloy steel feels properly rigid for the tooling work I'm doing.
