Installation Notes

Hex bit sockets are installed and removed by hand onto any compatible 1/4 inch drive tool. Ensure the drive tool is fully seated before applying torque to avoid rounding the fastener. Inspect sockets for wear or cracking before each use and replace damaged sockets immediately. No special tools or codes are required for use, but always de-energize or shut down equipment before accessing internal fasteners on live systems.
