Customer Reviews (4.8 / 5 · 5 reviews)

Avery ★★★★★

The hex heads on these grade 5 screws grab a socket perfectly without any slipping, and the zinc finish looks clean and durable. I used them to secure a motor mount on an industrial press, and they threaded in smoothly the whole way. A solid 100-count box for jobs like this.

Harper ★★★★★

The partially threaded design made these perfect for mounting a motor bracket where the smooth shank aligns through the flange. Wrenched on easily and the yellow zinc finish looks nice against the steel.

Nicholas H. ★★★★★

Grabbed these for replacing a stripped bolt on my tractor's mower deck, and the partially threaded section made alignment a breeze with the lock washer. The hex head grabs nicely with a socket, and they torqued down solid without any issues.
