The Genie 42175GT is a genuine OEM Hex Head Cap Screw, 3/8-24 x 1.25, built for Genie S-series telescopic boom lifts and TMZ-series trailer-mounted articulating booms. As a direct Genie OEM part, this screw is manufactured to the exact thread pitch, grip length, and head geometry specified for the applications it serves — so it seats and torques the same way as the original every time. Compatible machines include the S-120, S-125, S-100, S-105, TMZ-50/30, and TMZ-17/10. Cross-reference part number 42175GT against your machine's parts manual to confirm this is the correct fastener for your specific assembly before ordering.
Key Features
- Exact OEM Thread Specification — 3/8-24 fine-thread pitch and 1.25-inch grip length match the original fastener exactly, ensuring proper clamp load and seating without modification.
- Genuine Genie Quality — produced to OEM material and dimensional standards, so head strength and thread integrity hold up under the torque demands of aerial-lift assemblies.
- Direct-Fit Replacement — installs in the same position as the factory fastener with no rework to the mating components or surrounding hardware.
- Broad S-Series and TMZ Compatibility — fits the S-100, S-105, S-120, and S-125 telescopic booms as well as the TMZ-50/30 and TMZ-17/10 trailer-mounted articulating booms from a single part number.
- Structural Integrity Where It Counts — a fastener at the correct spec maintains proper joint clamping force; an incorrect or worn-out screw can allow movement, fretting, or joint failure in critical boom and chassis assemblies.
A hex head cap screw is a precision fastener used to clamp structural and mechanical assemblies together, with the hex head allowing controlled torquing to a specified value. On boom lifts and trailer-mounted booms, fasteners like this one appear throughout structural joints, pivot points, cover assemblies, and component mounts — locations where maintaining correct clamp load directly affects the integrity of the machine. Using the correct OEM-spec screw with the right thread pitch and grip length is essential; a fastener that is too short, too long, or cut to the wrong thread pitch will not develop proper clamping force and can work loose over time. Verify part number 42175GT in your Genie parts manual before ordering to confirm it is the right screw for your specific assembly.
