As a genuine Genie part, it is manufactured to the exact material grade and dimensional tolerances of the original hardware. Cross-reference part number 54177GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- Exact-Thread Fit — Cut to 1/2-13 thread pitch and 1.5-inch length to match original fastener dimensions precisely, seating correctly without rework.
- Genuine OEM Part — Sourced directly from Genie, ensuring the alloy grade, head geometry, and coating match what came off the assembly line.
- Broad Equipment Coverage — Fits Genie S and SX telescopic booms, Z and ZX articulating booms, TZ trailer-mounted booms, GTH telehandlers, RL light towers, and AL series units with vertical masts.
- Structural Integrity Assurance — Using the correct grade fastener in a rated joint keeps clamping loads within the designed range, preventing loosening or fastener fatigue over time.
A hex head cap screw is a fully threaded or partially threaded fastener with a hexagonal head designed to be driven by a wrench or socket. In structural and mechanical assemblies, the fastener's grade rating determines how much clamping force it can carry before yielding — substituting a lower-grade screw in a rated joint risks loosening, deformation, or eventual joint failure. The 1/2-13 thread designation specifies a half-inch major diameter on a coarse thread series, while the 1.5-inch grip length ensures proper thread engagement in the mating hole. Replacing a worn or damaged fastener with the correct OEM-spec part restores the joint to its original clamping specification.
