Chloe Q. ★★★★★

The unthreaded grip length on these bolts let me align the parts perfectly before tightening the nut. Zinc plating looks clean and they threaded smoothly into my steel brackets.

Aurora Y. ★★★★★

Needed these exact partially threaded bolts for a jig fixture where I wanted smooth engagement through the clearance hole, and the unthreaded grip length worked perfectly. Each bolt threaded in cleanly with no binding, and at this price for 70 pieces it's a solid value for general shop use.

Chloe ★★★★★

The zinc plating held up well during assembly, and the hex heads fit my socket perfectly without slipping. For the price, getting 70 of these 7-inch bolts with that clean grip section feels like a solid deal for any framing job.
