The Genie 981640GT Hex Head Cap Screw, 1/2-13 x 1.25 is a genuine OEM fastener designed for Genie and Terex portable light towers, including the AL4000, AL5000, RL4000, TML-4000, AL4, AL5, AL5 with Vertical Mast, RL4, and RL4 Vertical Mast. As a direct OEM replacement, this screw meets the exact thread pitch, head geometry, and material grade specified for these machines — so it fits the way the original did without rework or improvisation. Cross-reference part number 981640GT against your machine's parts manual to confirm it is the correct fastener for your specific application before ordering.
Key Features
- OEM-Grade Material and Dimensional Conformity — Manufactured to Genie's exact 1/2-13 thread and 1.25-inch length specification, ensuring the screw seats and torques correctly in the intended location.
- Direct OEM Replacement — Installs exactly as the original, with no chasing threads or adjusting hardware to make it fit.
- Broad Light Tower Fitment — Compatible across multiple Genie and Terex portable light tower families, including AL, RL, and TML series models.
- Structural Integrity Where It Counts — A fastener at the correct spec holds mating components firmly under load and vibration; an undersized or incorrect replacement can work loose over time and compromise the joint.
A hex head cap screw is a threaded fastener used to clamp or secure two or more components together at a defined torque. The hex head allows a wrench or socket to apply consistent clamping force, and the specified thread pitch — 1/2-13 in this case — determines how the screw engages its mating thread or nut. Using a fastener of the wrong length, thread pitch, or material grade risks an under-torqued joint that loosens under vibration or an over-stressed connection that can fail. Replacing a worn or damaged screw with the correct Genie OEM part maintains the joint as originally engineered.
