Cross-reference part number 6637GT against your machine's parts manual to confirm it is the correct fastener for your application. This screw fits across numerous Genie equipment families, including the GS-1930, GS-2632, GS-4047, S-60, S-65, Z-45/25J Bi-Energy, Z-135/70, GTH-844, GTH-1056, and many more models.
Key Features
- Genuine OEM Dimensional Conformity — Manufactured to Genie's exact thread pitch, diameter, and length specification, ensuring the 1/4-20 x 1.75 screw seats correctly in every intended application without rework.
- Direct OEM Replacement — This screw installs exactly as the original, requiring no modification to the fastener hole or mating hardware.
- Wide Equipment Compatibility — Fits GS scissor lifts, S and Z series boom lifts, GTH telehandlers, and a range of Genie personnel and material lift products, making it a practical stock item for mixed fleets.
- Structural Integrity Where It Counts — A correctly torqued fastener holds assemblies secure under dynamic loads and vibration. A stripped, missing, or incorrect screw can allow movement or loosening in critical joints.
- Genuine Genie Part — Sourced directly from Genie's OEM supply chain, so the grade, finish, and thread form are consistent with the hardware already on your machine.
A hex head cap screw is a standard threaded fastener used throughout equipment assemblies to clamp or secure components to a mating surface. The hex head allows it to be driven with a wrench or socket, providing controlled torque and a firm, repeatable clamp load. The 1/4-20 thread designation indicates a 1/4-inch nominal diameter with 20 threads per inch, and the 1.75-inch length determines how deep it engages the receiving thread or how far it passes through a clamped stack. When a fastener of this type is missing, damaged, or replaced with an incorrect grade or length, the joint it was meant to secure may loosen under vibration and operational stress, potentially compromising the assembly's integrity. Using the correct OEM specification screw restores the joint to its original design condition.
