The Genie 49379GT Hex Head Cap Screw, M8 X 1.25 X 25 is a genuine OEM fastener built for a wide range of Genie equipment, including S and SX telescopic boom lifts, GS scissor lifts, Z articulating boom lifts, GTH telehandlers, TMZ trailer-mounted booms, and TML light towers. As a genuine OEM part, it is manufactured to the exact thread pitch, grade, and dimensional spec required by the machine. Cross-reference 49379GT against your machine's parts manual to confirm it is the correct fastener for your specific unit and assembly point before ordering.
Key Features
- Correct Thread Spec, Every Time — Manufactured to M8 X 1.25 X 25 dimensions, matching the exact thread pitch and length called out in the Genie parts manual for each listed application.
- Genuine OEM Construction — Produced to the same material grade and torque specification as the original fastener, so it seats and clamps the way the engineer intended.
- Broad Equipment Coverage — A single part number that fits S and SX telescopic booms, GS scissor lifts, Z articulating booms, GTH telehandlers, TMZ trailer booms, and TML light towers, simplifying parts inventory across a mixed fleet.
- Direct Drop-In Replacement — Identical head geometry and thread form means it installs with standard tooling and no rework to mating components.
- Structural Integrity at the Joint — A fastener at the correct spec holds mated components at the designed clamp load; an under-spec or worn screw can allow movement, misalignment, or loosening under load and vibration.
A hex head cap screw is a fully threaded or partially threaded fastener with a six-sided head, driven by a wrench or socket to develop precise clamping force between two or more components. On Genie equipment, fasteners like this one appear throughout structural, mechanical, and panel assemblies, where the correct grade, thread pitch, and length are essential to maintaining joint integrity. Using a screw that does not match the specified dimensions can result in improper torque, thread stripping, or joint failure — making the genuine OEM spec the straightforward choice when servicing any of the machines this part covers.
