Edward ★★★★★

These things are hefty and the Grade 8 zinc coating looks flawless, so they should handle some serious torque. Full threading made threading into a tight frame a lot easier than I expected.

Eva ★★★★★

I needed bolts that wouldn't strip under heavy torque, and these Grade 8s drove in smoothly with a socket without a hint of rounding. The threads cut cleanly into the steel frame, and at 3 inches they gave me the bite I needed for a solid hold on my press. A full box of 45 like this will last me thr

Stella C. ★★★★★

Zinc plating looks even and smooth, and the threads are clean all the way down. I used a wrench on these for a tight machinery mount and the head didn’t strip at all. Solid for the price.
