The Genie 990181GT Hex Head Cap Screw, 3/8-16NCX1 is a genuine OEM fastener built for Genie AL series portable light towers, including the AL4000, AL5000, AL4, AL5, AL4L, and AL5L. Sourced directly from Genie, this screw matches the thread pitch, grip length, and grade specification of the original hardware used on the production line. Cross-reference part number 990181GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- Genuine OEM Grade and Thread Conformity — Manufactured to Genie's material grade and dimensional standards, ensuring the correct thread engagement and clamping load for the joint it secures.
- Direct Hardware Match — The 3/8-16NCX1 thread and length specification matches the original fastener exactly, dropping in without modification to existing hardware positions.
- Broad AL Series Coverage — Fits the AL4000, AL5000, AL4, AL5, AL4L, and AL5L Genie light towers, making this a practical stocking item for fleets running multiple AL series units.
- Structural Integrity at Every Joint — A correctly torqued, properly graded screw holds components securely in place. A stripped, corroded, or under-spec fastener compromises the joint and can lead to component movement or failure under load.
A hex head cap screw is a fully threaded or partially threaded fastener tightened with a wrench, used to clamp components together or secure assemblies to a frame or housing. The thread specification — 3/8-16NC — defines the diameter and coarse-thread pitch, while the 1-inch grip length determines how deep the fastener seats into the joint. When a screw is worn, stripped, or replaced with an off-spec substitute, proper clamping force is lost, which can allow components to shift or work loose during operation. Using the correct OEM fastener restores the joint to its designed holding strength.
