Customer Reviews (5.0 / 5 · 5 reviews)

Andrew U. ★★★★★

Torqued these down on a heavy-duty press bracket and the grade 5 steel held perfectly without any stretch. The partially threaded shank made alignment a lot easier than fully threaded bolts would have.

Riley ★★★★★

The yellow zinc coating on these feels a bit more durable than the plain steel ones I've used before. They tightened down cleanly with a socket on a heavy press frame without any binding.

Sofia ★★★★★

Needed a set of heavy-duty bolts for a jig I'm building, and these Grade 5 hex heads threaded in clean and snug. The partial threading made alignment easier than fully threaded ones I've used before.
