Customer Reviews (4.8 / 5 · 5 reviews)

Benjamin ★★★★★

I needed heavy-duty bolts for a press build, and these hex cap screws with their fully forged ASTM A193 B7 steel feel like they could hold a bridge together. The partially threaded 6" length was perfect for getting the grip I needed through thick plates without bottoming out.

Aurora ★★★★★

These 5/8-11 x 6" bolts threaded in smoothly during my equipment rebuild and the 70-count pack gives you plenty for multiple projects. The partial threading made them easy to start by hand before wrenching them down tight.

Jacob ★★★★★

Grabbed a pack of these for some heavy machinery repairs and the 6" length gave me just enough thread engagement for a thick bracket mount. The B7 alloy feels rock solid under the wrench, no bending or galling during installation.
