The Genie 1256450GT Hex Head Cap Screw, M6-1.0X20 is a genuine OEM fastener built for a wide range of Genie equipment, including SX telescopic boom lifts, Z articulating boom lifts, GTH telehandlers, and RL light towers. As a direct OEM replacement, this screw is manufactured to the same DIN 933 standard and 10.9 property class specified in Genie's own parts documentation, ensuring the correct grade and thread profile every time. Cross-reference part number 1256450GT against your machine's parts manual to confirm it is the right item for your unit before ordering.
Key Features
- Grade 10.9 Strength Rating — Manufactured to DIN 933 at property class 10.9, delivering the high tensile strength required for structural and mechanical fastening applications on Genie equipment.
- Correct Thread and Dimensional Spec — M6-1.0X20 thread and length dimensions match OEM specifications exactly, threading in cleanly without rework or adjustment.
- Zinc-Aluminum Bake (ZAB) Coating — The ZAB finish provides corrosion resistance suited to the outdoor and variable-weather environments these machines operate in.
- Broad Equipment Compatibility — Fits Genie SX super-boom telescopic lifts, Z and ZX articulating booms, GTH telehandlers, and RL series light towers, making it a practical stocking item for mixed Genie fleets.
- Genuine OEM Part — Sourced directly from Genie, this fastener carries the same part number found in the OEM parts manual, so there is no uncertainty about specification or interchangeability.
A hex head cap screw is a threaded fastener used to clamp, secure, or align components throughout a machine. The DIN 933 standard specifies full-thread geometry, meaning the thread runs the full length of the shank, which is important for correct engagement in the applications where it is called out. The 10.9 property class indicates a high-strength steel fastener — using a lower-grade substitute risks fastener failure under load, which can compromise the integrity of the assembly it secures. Replacing a worn, stripped, or missing screw with the correct OEM part, identified by part number 1256450GT, ensures the assembly is returned to its specified condition.
