The Genie 1252978GT Hex Head Cap Screw, 3/8-16 x 2.25 is a genuine OEM fastener built for Genie S series telescopic boom lifts, GS series scissor lifts, and Z series articulating boom lifts. As a direct OEM replacement, this screw is manufactured to the exact thread pitch, grade, and finish specified by Genie, ensuring a correct fit without modification. Cross-reference part number 1252978GT against your machine's parts manual to confirm this is the correct fastener for your specific unit and application.
Key Features
- Grade 8 Strength, ZAG Finish — Manufactured to Grade 8 tensile specifications with a zinc-alloy-coated (ZAG) finish that resists corrosion in outdoor and jobsite environments.
- Exact Thread and Dimensional Match — 3/8-16 thread pitch and 2.25-inch length match the OEM specification, seating correctly in the intended bore without rework or shimming.
- Broad Genie Fleet Coverage — Fits a wide range of Genie S series telescopic booms, GS series scissor lifts, and Z series articulating booms, making it a practical fastener to keep on hand for mixed fleets.
- Genuine OEM Part — Sourced directly from Genie, this fastener meets the same material and dimensional standards as the hardware installed at the factory, so clamping loads and joint integrity are maintained as designed.
- Structural Joint Integrity — A correctly specified fastener holds structural and mechanical joints at the designed clamp load. A worn, stripped, or incorrect replacement can allow joint movement that leads to premature component wear or connection failure.
A hex head cap screw is a high-strength threaded fastener used to clamp and secure structural, mechanical, and bracket connections throughout the machine. The Grade 8 rating indicates the fastener is engineered for high-load joints where tensile and shear forces are significant — common in boom, chassis, and platform assemblies on aerial equipment. When a fastener in one of these joints is missing, damaged, or replaced with an incorrect grade or thread spec, the joint can lose its designed clamp load, allowing movement, fretting, or eventual failure of the connected components. Using the correct OEM fastener — matched in grade, thread pitch, length, and finish — ensures the joint performs as the machine's engineers intended.
