Customer Reviews (4.6 / 5 · 5 reviews)

Steven ★★★★★

Used these for mounting a heavy gearbox on a press, and the fully threaded length gave me plenty of grip without bottoming out. The heat-treated steel feels solid, no bending or stripping during torquing.

Richard X. ★★★★★

I used these on a heavy flange connection and the full threading made alignment much easier. The threads cut clean and the hex head held torque really well.

Mia ★★★★★

Torqued these down on a pump baseplate today and they seated beautifully, no galling on the threads even without lube. The 2-1/4" fully threaded length gave me plenty of bite in the flanged nut. Solid feel right out of the box, exactly what I hoped for from B7 alloy.
