The Genie 990270GT Hex Head Cap Screw, 1/2-13 x 3.5 GR8 is a genuine OEM fastener built for Genie and Terex portable light towers, including AL, RL, and TML series models. As a direct OEM replacement, this screw is manufactured to the same grade and dimensional specification as the original hardware, ensuring a correct, secure fit without modification. Cross-reference part number 990270GT against your machine's parts manual to confirm it is the right fastener for your application before ordering.
Key Features
- Grade 8 Strength — Manufactured to GR8 specification, delivering the tensile strength required for structural and mechanical fastening on light tower equipment.
- Exact OEM Dimensions — 1/2-13 thread pitch and 3.5-inch length match the original fastener precisely, so the screw seats correctly in existing hardware without rework.
- Genuine Genie OEM Part — Sourced directly from Genie, this fastener carries the same part specification used on the production line, with no substitution or approximation.
- Broad Light Tower Compatibility — Fits AL4, AL4L, AL5, AL5L, AL5HT, RL4, RL4 LED, RL4000, AL4000, AL5000, TML-4000, and select vertical mast variants across the Genie and Terex light tower range.
- Structural Integrity — A correctly rated, properly torqued fastener keeps assemblies secure under the vibration and load cycles typical of towable light tower operation. A worn, stripped, or incorrect-grade screw can compromise the assembly it holds.
A hex head cap screw is a fully threaded or partially threaded fastener with a six-sided head designed to be driven by a wrench or socket. On portable light towers, fasteners like this one secure structural panels, mast components, and mechanical assemblies that must remain firmly joined through transport, setup, and extended runtime. When a screw is damaged, corroded, or stripped, it should be replaced with a fastener of the correct thread size, length, and grade — substituting a lower-grade or incorrect-length screw risks loosening or joint failure over time. Using the correct OEM-specified part ensures the assembly performs as designed.
