M16 X 60mm 平頭內六角止付螺絲 | 合金鋼 (25顆/包)

The hex socket drive made torquing these down in a cramped bracket a breeze, and the flat point seated squarely without walking off the surface. Alloy steel feels plenty rigid for the job, and a full pack of 25 means I've got spares for the next project.

Installing these in tight access points on a machine was so much easier thanks to the hex socket drive—held the Allen key securely without slipping. The alloy steel feels tough and the M16 threads engaged smoothly from the start.

The flat point seats perfectly against the shaft without walking, and the hex socket held up to some serious torque without stripping. These alloy steel screws feel rock solid for the price.
