Customer Reviews (4.8 / 5 · 5 reviews)

James ★★★★★

Used these to secure a new base plate on a punch press at work. The hex head grabbed nicely with a socket, and the partial threading made alignment much easier. Tough bolts for the price.

Leo T. ★★★★★

Needed a handful of these for a heavy equipment repair, and the hex heads let me torque them down properly without any fear of stripping. The all-metal yellow zinc finish feels durable, and the partial threading gave just the right grip in the bore. A solid 25-pack for precision fastening jobs.

Emily R. ★★★★★

I was glad these came in a 25-pack for a small equipment repair job. The yellow zinc coating looks solid and should hold up well in my shop.
