5/16-18 X 1-1/8" 六角機械螺絲 | 18/8 不鏽鋼 | 部分螺紋 (50個/包)

The partially threaded shank made alignment a breeze when I was bolting a steel bracket to the frame. These are solid, well-machined bolts that feel substantial.

The hex heads on these bolts grabbed my socket perfectly, and the 18/8 stainless steel gave me confidence they'll hold up in my outdoor shed project without rusting. The 50-piece pack arrived well-organized and exactly as described.

The partial threading is exactly what I needed for a tight bracket assembly—the unthreaded grip section seats perfectly against the frame without any wobble. All fifty arrived clean and uniform, no burrs or bent threads in the batch.
