براغي رأس سداسية داخلية 7/8-9 × 7" | محرك سداسي | فولاذ مقاوم للصدأ 18/8 (10 / عبوة)

The hex socket drive grabbed my Allen key perfectly with zero stripping, and the 18/8 stainless finish has that clean, machined look you want for a jig. I used all ten on a fixture build and every thread seated smoothly to the shoulder. These are solidly built for the price.

Pretty hefty screws, the 7" length was spot-on for aligning the press tooling I'm working on. The hex socket drive grabbed perfectly without any stripping.

The hex socket drive made tightening these into a jig frame effortless, and the 18/8 stainless steel finish looks clean and professional. I used three of them to secure a fixture on my milling table, and the full 7-inch length gave plenty of thread engagement.
