Customer Reviews (4.8 / 5 · 5 reviews)

Grace ★★★★★

These arrived nicely oiled and the fully threaded length is exactly what I needed for a thick flange setup. The hex heads gripped cleanly with both a socket and wrench, no stripped corners even where I had to torque them down.

Robert ★★★★★

The threading on these M16 bolts is nice and clean, so the nut went on smoothly without any binding. Much better than the random loose hardware I've had from other bins, and at 8.8 grade they feel plenty strong for my clamp fixture.

Emma ★★★★★

I was pleasantly surprised by the precision of the threading on these M16 bolts—they threaded into place with zero binding. The hex head is a nice, solid shape that gave my socket wrench a firm grip for tightening. Exactly what I needed for assembling a heavy-duty machine stand.
