Frequently Asked Questions
A SEM screw is pre-assembled with a washer for easier installation. Graco uses it to secure panels or control boxes without needing separate washers, improving assembly consistency and reliability.
The 113045 screw is designed for Graco control assemblies. Using it in non-compatible machines may result in improper fit or damage due to truss head size and washer design.
Align the screw with the panel or control box hole, ensure the washer seats properly, and tighten gently. Avoid over-torquing to prevent damage to thin metal or plastic panels.
