Using the Greenlee 54268 Socket Head Screw-Cap is straightforward. First, make sure your Greenlee 855 Smart Bender is turned off and unplugged. Then, locate the area where the old screw needs to be replaced. Unscrew the old one and screw in the new Greenlee 54268. It has a 1/4 - 20 thread, so it should fit snugly. When handling the screw, be careful not to drop it as it's a small part. For maintenance, periodically check the screw for any signs of wear or damage. If you notice any issues, replace it promptly to keep your bender working well. Also, store the screw in a dry place when not in use to prevent rusting.
