براغي تثبيت سداسية برأس كوبية بنقطة رقعة نايلون مقاس 5/8-11 × 2-1/2 بوصة | فولاذ سبائكي (50/عبوة)

That hex socket drive made installing these screws in a tight spot a breeze, no stripped heads and no guesswork. The cup point tip made alignment simple, and the nylon patch locks them in place perfectly.

Got tired of stripping set screws on my lathe compound rest, but these nylon patch ones hold snug even under vibration. Installing them is quick with the hex drive, and the cup point bites into the shaft without marring it.

The cup point on these really digs in and holds firm, even on a slightly worn shaft. The nylon patch keeps them from backing out, which is exactly what I needed for a high-vibration application.
