M8-1 x 30mm 六角頭螺絲 | 10.9級鋼鍍鋅 | 全螺紋 (200 顆/包)

I needed a solid batch of M8-1 x 30mm fasteners for a jig I'm assembling, and these hex heads fit my wrench perfectly without rounding. The zinc plating looks even and corrosion-resistant out of the bag.

I used these for a heavy equipment jig and the class 10.9 steel held torque perfectly. The hex heads sat flush in my wrench without any rounding.

The zinc plating on these screws handled a few rainy days during my outdoor assembly project without any rust. They threaded perfectly into predrilled holes on a steel frame, and the hex head made driving them in with a socket wrench a breeze.
