The Genie 990270GT is a genuine OEM Hex Head Cap Screw, 1/2-13 x 3.5 GR8 built for Genie and Terex AL and RL series light towers. As a genuine OEM fastener, this screw is manufactured to the exact thread pitch, grip length, and Grade 8 strength specification called out in the Genie parts manual. Cross-reference part number 990270GT against your machine's parts manual to confirm it is the correct fastener for your unit before ordering.
Key Features
- Exact Thread and Length Specification — The 1/2-13 thread pitch and 3.5-inch grip length match the OEM callout precisely, ensuring correct seating and clamping force at installation.
- Genuine OEM Part — Supplied directly from Genie, this fastener carries the same specification as the original hardware, with no risk of dimensional variation from an unvetted substitute.
- Broad Light Tower Fitment — Fits multiple AL and RL series Genie and Terex light towers, including the AL4000, AL5000, AL5HT, RL4000, RL4, and AL4, making it a practical stocking item for fleets running these units.
- Direct Installation — This screw installs in place of the worn or damaged original without rework, keeping service time short and the unit back in service quickly.
A hex head cap screw is a structural fastener that clamps two or more components together under a controlled load. The hex head allows torque to be applied with standard hand or power tools, while the Grade 8 rating ensures the fastener can withstand the vibration, mechanical stress, and environmental exposure common on portable light tower equipment. When a fastener in this position stretches, strips, or fails, the joint it secures can loosen — leading to misalignment, wear on mating components, or an unsafe assembly. Replacing a compromised screw with the correct OEM-specified hardware restores the clamping integrity the assembly was engineered to maintain.
