3/8-24 X 1-1/8" 六角頭螺絲 | 美國製造 | 8級鋼黃鋅鍍層 | 全螺紋 (100個/包)

I needed a fresh batch of hex bolts for a machinery repair, and the yellow zinc coating on these feels both durable and exactly as described. The hex heads fit my socket perfectly, which made the final torque-down a breeze.

The threads are clean and cut perfectly, so these bolts started easily by hand. I used them to repair a piece of farm equipment, and the Grade 8 strength gives me confidence they'll hold up under heavy load.

Installing these on a skid loader attachment and the threads cut clean with zero binding. The hex heads took a socket wrench perfectly and the yellow zinc coating looks like it’ll hold up well outdoors.
