Steven N. ★★★★★

The unthreaded grip section on these is perfect for aligning parts without the threads chewing into the holes. The stainless finish looks clean and the heads seated nicely with a standard wrench. Just the right amount of thread for a solid clamp on a 2x4 frame.

Zoe ★★★★★

I needed a bolt with a smooth shank for a tight assembly, and the 4-inch length on these stainless steel hex heads worked perfectly for my project without any threading issues.

Julian ★★★★★

The unthreaded grip length on these bolts made alignment in my steel brackets much easier than fully threaded ones. They fit perfectly through a 1/4-inch clearance hole with no wobble.
