SCREW, HCC, 3/8-16 X 1.50

The Genie 8516GT is a genuine OEM Hex Head Cap Screw, 3/8-16 x 1.50, engineered for the broad range of Genie and Terex aerial work platforms, scissor lifts, boom lifts, light towers, and personnel lifts it supports. Sourced directly through the OEM supply chain, this fastener meets the exact dimensional and material specifications called out in Genie parts manuals, so it threads in cleanly and torques to spec without guesswork. Cross-reference part number 8516GT against your machine's parts manual to confirm the correct application before ordering. Fitment spans an extensive equipment lineup including Genie GS scissor lifts, S and Z series boom lifts, TML light towers, QS stock-picking lifts, GR Runabout vertical mast lifts, GTH telehandlers, AWP and IWP personnel lifts, DPL dual personnel lifts, TZ trailer-mounted booms, and a wide range of legacy Genie material lifts and specialty lift lines.

Key Features

• Correct Thread and Length Every Time — 3/8-16 UNC thread form and 1.50-inch grip length match the OEM specification exactly, eliminating the risk of cross-threading or fastener bottoming out before clamping load is achieved.
• Genuine OEM Grade Material — Manufactured to the same tensile and hardness grades as the original hardware, so the screw handles the shear and clamping loads it was designed for without yielding or stretching under torque.
• Direct Drop-In Replacement — The hex head drive profile and unified thread pitch are identical to the factory-installed fastener, allowing installation with standard tooling and no rework to mating components.
• Broad Cross-Fleet Coverage — A single part number covers Genie GS scissor lifts, S and SX telescopic booms, Z and ZX articulating booms, TZ trailer booms, GTH telehandlers, TML light towers, and multiple personnel and material lift lines, simplifying stock management across a mixed fleet.
• Structural Integrity Where It Counts — On aerial work platforms and boom lifts, fastener failure at structural or safety-critical joints can compromise platform stability. Using the specified OEM screw maintains the clamping integrity those joints depend on.

A hex head cap screw is a fully threaded or partially threaded fastener with a hexagonal head designed to be driven by a wrench or socket, providing a controlled and measurable clamping force when torqued to specification. In aerial work platforms and boom lifts, fasteners like this one secure structural panels, hydraulic component brackets, drive assemblies, and platform components where consistent clamp load is essential to safe operation. When a fastener stretches, strips, or is substituted with an incorrect grade or size, joint integrity is compromised — leading to loosening under vibration, component misalignment, or, in worst cases, structural joint failure. Replacing worn or damaged hardware with the correct OEM-specified screw restores the designed clamping force and keeps the assembly performing as intended.
