مسامير آلية سداسية 1/4-20 × 3-1/4 بوصة | فولاذ مطلي بالزنك | ملولبة جزئياً (100/عبوة)

I've been using these bolts for a few small framing projects, and the partially threaded shank makes it easy to get a secure hold without the threads binding. The zinc plating seems durable so far, and the 3-1/4 inch length is just right for joining two 2x4s.

The unthreaded grip section on these 1/4-20 bolts gave me a much cleaner fit when sandwiching a steel bracket to a wooden frame—no wasted thread digging into the wood. Zinc plating looks even and hasn't chipped after a week of outdoor use, though the package count was spot-on at 100. Definitely a so

These bolts have a solid grip length that made mounting a metal bracket feel much more secure than using fully threaded ones. The zinc coating looks clean and held up fine against my wrench.
