براغي غطاء مقبس 5/16-18 × 1-1/4" | محرك سداسي المقبس | كامل الخيط | برونز سيليكون (100/عبوة)

Used a handful for a jig I was building, and the hex socket drive made installation quick with no stripping. The silicon bronze has a nice color that stands out from standard steel, and the full thread gives a solid grip.

The silicon bronze finish is exactly what I wanted for a marine-adjacent jig build—no corrosion worries after a few salty days in the shop. Each of the hundred screws threads cleanly into tapped holes without any binding, and the fully threaded length gives me plenty of grip in tight spots.

I used these for a custom jig build and the hex socket drive made installation much smoother than a slotted head would have. The fully threaded length gripped perfectly in the silicon bronze.
