The Genie 1257453GT is a genuine OEM Hex Head Cap Screw, 1/2-13x.875, 8, ZAG built for a range of Genie equipment including RL4 light towers, S-60 XC and S-65 XC telescopic boom lifts, S-60 HF and S-65 HF booms, and the GTH-1056 telehandler. As a direct OEM replacement sourced from Genie, this screw matches the exact thread pitch, grade, and coating specified for these machines. Cross-reference part number 1257453GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- OEM-Grade Fastener Spec — Grade 8 construction with a ZAG (zinc-alloy) corrosion-resistant coating, meeting the same material and dimensional standard as the original hardware.
- Exact Thread and Size Match — 1/2-13 thread pitch and .875-inch length ensure this screw seats correctly in the factory-specified location without reworking the mating thread.
- Broad Genie Fitment — Compatible with RL4 series light towers, S-60 XC and S-65 XC telescopic booms, S-60 HF and S-65 HF booms, and the GTH-1056 telehandler, covering multiple Genie equipment families.
- Structural Integrity — A correctly torqued, properly graded fastener holds assembled components securely. A stripped, corroded, or under-spec screw can cause joint movement, structural loosening, and accelerated wear on surrounding components.
- Genuine OEM Confidence — Supplied by Genie as an authorized replacement part, ensuring the fastener is traceable and built to the same specification as the original.
A hex head cap screw is a threaded fastener used to clamp or secure components together at a defined clamping force determined by its grade and size. Grade 8 hardware delivers a higher tensile and proof-load rating than standard fasteners, making it appropriate for joints that carry mechanical load or vibration — conditions common across boom lifts, light towers, and telehandlers. When a fastener in a structural or mechanical joint corrodes, strips, or is replaced with an under-grade substitute, clamping force is compromised and the joint can shift or loosen under operating stress. Using the correct OEM-spec replacement maintains the integrity of the joint as designed.
