براغي تثبيت بنقطة كوب مع رقعة نايلون 5/8-11 × 1-1/2" | فولاذ سبائكي (50 / عبوة)

The cup point really bites into the shaft without marring it, and the nylon patch holds them snug even under vibration. I used a dozen on a jig fixture and they haven't backed off a bit.

The hex socket drive made installing these in a tight corner of my workbench a breeze. The nylon patch holds them securely without loosening, and the cup point tip gives a clean, flush finish.

I've been using these cup point screws for mounting brackets in tight spots, and the hex socket drive makes them easy to install even with limited swing room. The nylon patch holds well without backing out, which saves me from constant re-tightening.
