We have 12 #2OM Centerless Grinders and 10 full-time operators. Level 1 Fasteners feels that centerless grinding is a very important part of our manufacturing process, it improves fasteners quality and produces consistent lap-free threads. Centerless grinding also ensures the dimensions are consistently in tolerance and creates a cosmetically nicer looking part with a ground finish.
We do mostly infeed grinding for headed fasteners, but also have the capability to do thru-feed grinding for long studs or threaded rods. Our standard tolerance in this department is +/- .0002 inches.
