براغي غطاء المقبس 3/4-10 × 4-1/2 بوصة | محرك مقبس سداسي | ملولبة جزئيًا | فولاذ مقاوم للصدأ 316 (10/عبوة)

The partial threading on these 316 stainless screws really helps them grip securely in my jig setup without binding. They drive smoothly with a hex key and feel solidly built. Exactly what I needed for a corrosive environment.

Installed these in a marine-grade outdoor assembly and the 316 stainless held up perfectly against a saltwater spray test. The hex socket drive seated cleanly without any stripping.

Used three of these on a heavy-duty jig I'm building, and the hex socket drive made tightening them in a tight spot much easier than a hex head would have. The 316 stainless feels solid and corrosion-resistant, which is exactly what I needed for outdoor tooling.
