M16 X 20mm 全狗點內六角止付螺絲 | 合金鋼 (50個/包)

Installing these in a tight spot under the dash was a breeze thanks to the hex socket drive—no slipping at all. The full dog point tip seated perfectly into the pre-drilled holes, saving me from chasing any misaligned threads. They feel solid and reliable for the industrial shelving project I'm on.

The hex socket drive gave me just the leverage I needed to secure these in a tight engine bay spot. The alloy steel feels properly tough, no stripping or bending under firm torque. These are a solid upgrade from the standard bolts I was using before.

The full dog point tip seated perfectly in a recessed hole, and the alloy steel feels solid and durable. These M16 screws torqued down evenly without any stripping, exactly what I needed for a heavy-duty fastening job.
