Installation Notes

Set screws are typically installed by licensed technicians and maintenance professionals using a correctly sized hex key or Allen wrench matched to the socket drive. Always de-energize and lock out equipment before tightening or loosening set screws on rotating components such as motor shaft collars or pulleys. Do not overtighten set screws, as doing so can damage shaft surfaces or strip threads. Refer to equipment manufacturer torque guidance where applicable.
