براغي رأس سداسي مقاس 7/16-14 × 7/8 بوصة | فولاذ درجة 5 أصفر زنك | كامل الخيوط (100 / عبوة)

Used a dozen of these to bolt a new motor mount on my press, and the grade 5 steel held up perfectly under heavy torque. The yellow zinc coating is a nice touch

Pulled these out to replace some worn bolts on a press, and the Grade 5 steel threads caught perfectly without any binding. The yellow zinc coating is a nice bonus for rust resistance. They're exactly what I needed for the job.

These hex bolts threaded smoothly into the mounting plate with no binding at all, and the hex head gave my socket a solid grip without slipping. I've been using them to secure heavy brackets on a steel frame, and the yellow zinc finish still looks clean after a few days of assembly work.
