Customer Reviews (4.8 / 5 · 5 reviews)

Ella ★★★★★

The hex drive on these cap screws sits deep and doesn't strip, even with a high-torque driver. They threaded smoothly into a steel frame I’m assembling, and at 600 per pack, the value is solid for shop use.

Riley P. ★★★★★

Got these for a production line rebuild and the hex heads held up perfectly under a torque wrench without any stripping. The class 8.8 steel seems solid for the price, and the full threading made alignment quick. Exactly what I needed for that many fasteners.

Andrew ★★★★★

Needed a full box of M6 bolts for a batch of machine guards and these are exactly what we use—strong 8.8 steel, clean threads, no jamming. The 30mm length worked perfectly for sandwiching two steel plates together.
