But what I can say about these is all good. There were no flaws in black oxide coating, the threads were well-machined and smooth.The bolts arrived on time and are now quietly doing their job. It's all you really want from hardware. ### ⭐⭐⭐⭐⭐ These a good bolts for replacing Philips head screws on DW735 Planer *by D***. on November 3, 2024* These a good bolts for replacing the cheap, easy to strip, philips head ones to hold the roller clamps and guards in place on the DW735 Planer.
