Key Features
- Exact Thread Specification — 3/8-16 x 3.5 threading and length match the original fastener, so this screw seats correctly without rework or shimming.
- Genuine OEM Quality — manufactured to Genie's original specifications, ensuring dimensional conformity and correct grade marking for confident installation.
- Broad Equipment Compatibility — fits Genie GR mast lifts, S and Z series booms, GTH telehandlers, TZ trailer-mounted booms, and Superlift Advantage units across multiple equipment families.
- Direct Drop-In Replacement — hex head cap configuration matches the original fastener pattern, allowing straightforward installation with standard tooling.
A hex head cap screw is a fully threaded or partially threaded fastener used to clamp, secure, or join structural and mechanical components on the machine. A fastener installed at the wrong grade or thread specification can loosen under vibration or fail to hold clamping load, leading to joint movement and accelerated wear on the surrounding components. Replacing a damaged or missing screw with the correct Genie 6605GT restores the joint to its original holding specification.
