براغي رأس سداسي 1/4-20 × 1-1/8 بوصة | صناعة أمريكية | فولاذ درجة 8 مطلي بالزنك الأصفر | كامل الخيوط (200/عبوة)

I needed a bulk box of fully threaded 1/4-20s for a jig build and these Grade 8s threaded cleanly into tapped holes without any binding. The 1-1/8" length is just right for clamping two pieces of 1/4" plate without bottoming out.

The yellow zinc finish on these Grade 8 bolts is holding up perfectly in a slightly damp shop environment, no rust after a month. Threads cut clean and the hex heads don't strip under moderate torque.

Bought these for a clamping fixture and the yellow zinc finish is holding up way better than the plain steel bolts I usually grab. The threads are clean and the hex heads seated perfectly in my socket, no stripping issues on the first dozen or so.
