براغي رأس أسطوانية 1/2-13 × 3-1/2 بوصة | محرك سداسي | خيط جزئي | ستانلس ستيل 316 (25/حزمة)

The partially threaded shank made these perfect for securing a thick bracket without needing a separate spacer. They drove in smoothly with my hex key and the 316 stainless should handle the outdoor moisture just fine.

The 316 stainless steel on these socket cap screws held up perfectly during my marine jig assembly, no rust after weeks of salt spray exposure. The partially threaded design made alignment in tight spots much easier than fully threaded bolts.

The hex drive on these 1/2-13 screws gripped perfectly with my Allen wrench, no stripping at all. Used them to bolt down a heavy-duty tooling fixture, and the 316 stainless feels solid and corrosion-resistant. Exactly what I needed for a demanding assembly.
