Customer Reviews (4.8 / 5 · 5 reviews)

Nicholas G. ★★★★★

I was a little worried the partial threading wouldn't give enough grip, but these bolts cinched down a heavy motor mount perfectly. The hex head gave my socket a solid bite, and the finish is clean with no burrs.

Leo G. ★★★★★

These hauled a heavy gearbox into place without a hint of flex, and the 2-1/4" length gave just the right grip for our flange setup. The alloy steel finish is clean, not greasy or coated in that annoying black oxide. Exactly what I needed for a permanent fix.

Chloe ★★★★★

The partial threading on these B7 bolts is spot on—grips cleanly without binding up mid-torque. They cinched down my equipment mount with zero deformation, and the hex heads seated perfectly in my wrench. Solid buy for heavy assembly work.
