1/4-20 × 4" مسامير ماكينة سداسية | فولاذ مقاوم للصدأ 18/8 | ملولبة جزئياً (50/عبوة)

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.

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.

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.
