SCREW, HHC, 1/4-20 X 1.5

The Genie 6145GT is a genuine OEM Hex Head Cap Screw, 1/4-20 x 1.5, engineered for an exceptionally wide range of Genie and Terex equipment including GS scissor lifts, S and SX telescopic boom lifts, Z and ZX articulating boom lifts, GTH telehandlers, TML light towers, and Genie material lifts and personnel lifts. As a genuine OEM part, this screw is manufactured to the exact thread pitch, head dimensions, grade, and torque specification called out in the Genie parts manual — so it seats and clamps exactly as the original design requires. Cross-reference part number 6145GT against your equipment's parts manual to confirm the correct application before ordering. With coverage spanning scissor lifts, booms, telehandlers, light towers, and manual lift lines, this fastener is a high-demand service item worth keeping in stock for scheduled maintenance and field repairs alike.

Key Features

• Genuine OEM Thread and Grade Spec — Manufactured to the exact 1/4-20 thread pitch and 1.5-inch length specified by Genie, ensuring correct clamping load and torque retention in every application.
• Direct-Fit Installation — Matches the original fastener profile and head drive pattern precisely, so the screw seats flush and drives without modification using standard tooling.
• Broad Equipment Coverage — A single part number spans GS scissor lifts, S and SX telescopic booms, Z and ZX articulating booms, GTH telehandlers, TML light towers, and Genie material and personnel lift lines.
• Structural Connection Integrity — A correctly spec'd fastener maintains the designed clamping force at panels, guards, and structural joints; an incorrect thread pitch or under-grade substitute can lead to loosening, vibration damage, or fastener failure.
• Safety-Critical Torque Retention — On aerial lifts and telehandlers, fastener integrity at platform, boom, and structural attachment points is a genuine safety consideration — using the OEM-spec screw ensures the connection performs as engineered.

A hex head cap screw is a fully threaded or partially threaded fastener with a six-sided head designed to be driven by a wrench or socket, providing high and consistent clamping force at structural, panel, and component attachment points throughout a machine. In aerial work platforms and telehandlers, fasteners like this one secure everything from access panels and guard covers to hydraulic component brackets and structural assemblies, meaning a stripped, wrong-grade, or incorrect-length substitute can compromise the integrity of the joint it holds. When a fastener of this type fails — through cross-threading, corrosion, or substitution with an incorrect spec — the joint it secures can loosen under vibration or load, making prompt like-for-like replacement with the correct OEM part the safest and most straightforward repair.
