مسامير آلية سداسية 5/16-18 × 1-1/2" | نحاس | خيوط جزئية (70 / عبوة)

These are perfect for a marine project I’m working on—the partially threaded shank gives just the right grip length without needing extra washers. Solid brass with clean threads, and the 70-count pack will last me a while.

The partially threaded grip length made alignment through the clearance holes noticeably easier than dealing with fully threaded bolts. I’ve used about forty of them so far and every one threaded smoothly without a single stripped head.

The hex heads seated cleanly with a standard wrench, no stripping or rounding on the first dozen I’ve used. The partial thread gave me a solid grip length for a snug fit through my steel brackets, and the brass finish looks sharp on the project.
