Elizabeth ★★★★★

The yellow zinc finish on these is spotless and seems durable—no flaking even after a few hard turns. At 1-3/4 inches, the partial threading gave me exactly the grip I needed for a sturdy frame assembly. Solid, uniform threads throughout the package.

George ★★★★★

I've torqued these down to spec with a socket wrench and the hex heads didn't strip at all, which is more than I can say for some cheaper bolts. The partially threaded length is exactly right for my equipment mounts, and a full box of 100 means I've got spares for the next job.

Victoria ★★★★★

Yellow zinc held up great during assembly, and the hex heads seated perfectly with a socket. These are solidly made for the price, I’ll be ordering another pack for the next job.
