براغي مقبس بنقطة نصف كلب مغطاة بالنايلون #8-32 × 5/8 بوصة | فولاذ سبائكي (250 / عبوة)

The nylon patch holds tight even after I adjusted my alignment three times, and the hex drive gave me plenty of torque in a cramped spot. These are exactly what I needed for locking down my machine’s guide rails.

I've been using these set screws on a jig that sees constant vibration, and the nylon patch holds tight without backing out. The half-dog point bites into the shaft cleanly, and the hex socket makes them easy to install in cramped spots. Exactly what I needed for a reliable, permanent hold.

The nylon patch locks them in place perfectly, no more worrying about them backing out on vibrating machinery. These half dog point screws are solid alloy steel and the hex drive bites well even in awkward angles, a solid buy for the price.
