براغي رأس سداسي 1/4-20 × 1-1/2 بوصة | فولاذ درجة 5 زنك أصفر | خيط جزئي (200 / عبوة)

I needed partially threaded 1/4-20 bolts for a machinery guard, and these hex heads fit my socket perfectly without any slop. The 1-1/2 length was spot on for the application, and the pack of 200 should last me through several projects.

The yellow zinc coating on these is much more consistent than other bulk bolts I've tried, and they thread smoothly into tapped holes without binding. Used them to mount a motor on a jig and the partial thread let me cinch it down tight without stripping.

Needed a batch of sturdy bolts for reassembling a press brake guard, and these Grade 5s with yellow zinc fit like a charm. The partially threaded shaft made seating them through stacked brackets much easier than with fully threaded alternatives.
