Genie 6637GT Hex Head Cap Screw, 1/4-20 x 1.75

The Genie 6637GT is a genuine OEM Hex Head Cap Screw, 1/4-20 x 1.75 built for a wide range of Genie equipment, including GS scissor lifts, S and Z series boom lifts, GTH telehandlers, and numerous vertical mast lifts, material lifts, and light towers. As a direct OEM replacement, this screw is manufactured to the same specifications as the original hardware installed at the factory. Cross-reference part number 6637GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.

Key Features

• Genuine OEM Dimensional Conformity — Threaded to the exact 1/4-20 specification and 1.75-inch length of the original, ensuring correct torque engagement and secure clamping without rework.
• Direct Drop-In Replacement — Matches the thread pitch, head geometry, and length of the factory-installed fastener so it seats correctly wherever this screw is specified on the machine.
• Broad Equipment Coverage — A single part number spans GS scissor lifts, S and Z series boom lifts, GTH telehandlers, QuickStock mast lifts, AWP and IWP personnel lifts, Dual Personnel Lifts, material lifts, and Genie light towers.
• Structural Integrity Where It Counts — A correctly installed fastener maintains the clamping load that keeps assemblies tight and properly aligned; a stripped, corroded, or incorrect-length screw can allow joint movement and accelerate wear on surrounding components.

A hex head cap screw is a threaded fastener used to join or secure components throughout a machine's structure and assemblies. The hex head allows a wrench or socket to apply precise torque, creating the clamping force that holds mating parts firmly in position. When a screw is worn, cross-threaded, or of the wrong length, the joint it secures can work loose over time, leading to misalignment or damage to surrounding hardware. Replacing a suspect fastener with the correct OEM item restores the original clamping specification and keeps the assembly performing as intended.
