Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the exact M8 X 1.25 X 120 thread pitch and length specification, ensuring correct torque engagement and seating in the original fastener location.
- Direct OEM Replacement — Matches the factory fastener precisely, dropping into place without modification for a straightforward swap during maintenance or repair.
- Broad Boom Lift Coverage — Fits Genie S-series telescopic booms and the Z-80/60 articulating boom, covering a wide range of large-platform boom lift models in a single part number.
- Structural Integrity You Can Count On — A fastener at the correct spec holds assemblies securely under the dynamic loads and vibration that large boom lifts encounter in daily operation. An incorrect or worn fastener risks joint loosening and unplanned repairs.
- Safety-Critical Application — Boom lift fasteners are structural components. Using the correct OEM-grade screw at the specified size and thread pitch is essential to maintaining the clamping force that keeps assemblies safely secured at height.
A hex head cap screw is a threaded fastener with a six-sided head designed to be driven with a wrench or socket, providing high clamping force when torqued to specification. On large boom lifts, these screws secure structural and mechanical assemblies that must remain firmly joined through the constant movement, extension, and load cycles the machine experiences. When a screw is damaged, cross-threaded, or missing, the joint it holds can work loose over time, leading to play in the assembly or a fastener failure that takes the machine out of service. Replacing a worn or damaged screw with the correct OEM part — matched to the exact thread pitch and length — restores the joint to its intended clamping specification and keeps the machine operating as designed.
