براغي رأس سداسي 5/16-18 X 1-1/8" | درجة 8 فولاذ أصفر زنك | ملولبة بالكامل (1200/عبوة)

Needed a solid batch of fasteners for a trailer repair job, and these grade 8 cap screws with the yellow zinc held up perfectly under heavy torque. The hex head gave my socket a good bite without rounding off, and having 1,200 in one package means I won't run out for a while.

These are perfect for our assembly line jigs; the grade 8 hardness holds up under constant torque without stripping. The yellow zinc coating gives them a consistent, corrosion-resistant finish that looks good too.

Bought these for a machine rebuild and the yellow zinc finish is holding up nicely without any corrosion. The Grade 8 hardness makes them feel rock solid when torquing down, and the fully threaded length gave me plenty of grip. Exactly what I needed for the job.
