Violet S. ★★★★★

The thread matched perfectly on my angle grinder, and the plastic material feels sturdy enough for daily sanding work. No wobble at all during use, which was my main concern.

Jason ★★★★★

Switched to this plastic backing plate after wearing out my old metal one—the threads fit perfectly on my 5/8-11 grinder and it holds discs securely without any wobble.

Owen L. ★★★★★

The 5/8-11 thread fit my grinder perfectly, no wobble at all once I tightened it down. This black plastic backing plate feels solid enough for everyday sanding, and the 4 1/2" size matches my discs exactly.
