مسامير آلة سداسية 1/4-20 × 1-3/8 بوصة | ستانلس ستيل 18/8 | ملولبة جزئياً (50 / عبوة)

The unthreaded grip length on these made alignment in my jig much easier than with fully threaded bolts. They went in smooth with a standard 7/16" socket, and the 18/8 stainless finish looks clean against the aluminum.

I needed bolts with a real grip section for a frame assembly, and these 1/4-20 x 1-3/8" stainless ones fit perfectly in the unthreaded portion. The 18/8 material feels solid and should resist rust well outdoors.

The partially threaded shank made alignment a breeze when I bolted a steel bracket to a wooden bench—no more fighting with threads catching early. The 18/8 stainless finish looks clean and feels solid, and the 50-count box is a great value for the price.
