Benjamin ★★★★★

The hex head on these cap screws grabbed my socket wrench perfectly without any slipping, and the zinc plating looks clean and durable. I used them to bolt down a heavy-duty press table, and the partial threading made alignment much easier than fully threaded bolts. Exactly what I needed for industr

Leo N. ★★★★★

These 5/8-11s are exactly as spec'd—the zinc plating is smooth and even, and the partial threads make seating them in a flange joint way easier than a fully threaded bolt. I torqued a set down on a press frame and they held perfectly with zero galling. For a hundred pieces, the price is hard to beat

Sophia ★★★★★

I used these to secure a heavy-duty workbench frame, and the grade 8 steel gives me real confidence in the load capacity. The partial threading made it easy to start them by hand before torquing down with a socket.
