The Genie 990180GT Hex Head Cap Screw, 3/8-16 NC X 1, GRD 2, Y is a genuine OEM fastener built for Genie AL5 with Vertical Mast and RL4 Vertical Mast light towers, including the RL4 LED Vertical Mast variant. Sourced directly from Genie, this screw matches the original thread pitch, grade, and finish called out in the factory parts manual. Cross-reference part number 990180GT against your machine's parts manual to confirm it is the correct fastener for your specific unit before ordering.
Key Features
- OEM Grade and Finish — Manufactured to the Grade 2 specification with the correct Y finish, matching the original fastener in thread form and material grade — no substitutions or compromises.
- Exact Thread Specification — 3/8-16 NC X 1 threading installs directly into the original tapped location on the vertical mast assembly without modification.
- Confirmed Fitment — Designed for Genie AL5 with Vertical Mast, RL4 Vertical Mast, and RL4 LED Vertical Mast light towers.
- Structural Integrity — A correctly specified fastener holds mast components securely in alignment; an incorrect grade or thread pitch can allow joint movement or connection failure under load.
- Genuine Genie OEM Part — Supplied by Genie as a genuine OEM replacement, ensuring the fastener meets the same standards as the original hardware installed at the factory.
A hex head cap screw is a threaded fastener used to clamp or secure components together within an assembly. The hex head allows torquing to a specified value with standard wrenches or sockets, ensuring the joint is held at the correct clamping load. Using a fastener of the wrong thread pitch, length, or grade risks stripping threads, under-clamping the joint, or allowing structural movement — all of which can accelerate wear on surrounding components. Replacing a worn or damaged screw with the correct OEM part restores the joint to its original specification.
