براغي ذات رأس أسطواني 5/16-18 × 3 بوصة | محرك سداسي | ملولبة جزئيًا | فولاذ مقاوم للصدأ 316 (50 / عبوة)

Had to swap out some old bolts on a saltwater dock fitting, and these 316 stainless cap screws fit perfectly with no corrosion worries. The hex socket drive made installation a breeze with my T-handle wrench.

The partially threaded design made installation in tight spots much easier than I expected. These 316 stainless screws fit perfectly into my tooling jig, and the hex drive gripped securely without stripping. Solid quality for precision assemblies.

Used these for a custom jig I’ve been building, and the partially threaded design gave me just the right grip without bottoming out. They’re solid 316 stainless, so no rust worries even in my damp garage. Took a bit of torque without stripping, which is all I ask for.
