Here’s a close-up of the Delta Engineering Model SRP1 short-run, weigh-counter filling 50 pieces of a 5/16-18 X 3/4 Hex Washer Head Cap Screw into a bag. The machine does the filling so the operator can do the closing and labeling. Being an easy to use, fast to changeover, semi-automatic system, the operator only touches product to correct the final count much like a check weighing system.
