Key Features
- Grade 10.9 Strength Rating — Property class 10.9 construction delivers the high tensile and proof-load ratings required for structural and load-bearing fastener applications on heavy aerial equipment.
- DIN931 Dimensional Conformity — Manufactured to the DIN931 standard for partially threaded hex head cap screws, ensuring the thread pitch, shank length, and head geometry match OEM requirements exactly.
- ZAB Corrosion-Resistant Finish — The zinc-aluminum-based coating resists corrosion from outdoor exposure and jobsite conditions, supporting the long service life Genie expects from OEM hardware.
- Direct OEM Replacement — Sourced directly from Genie, this fastener installs in place of the original without modification, preserving the engineered clamp load and joint integrity of the assembly it secures.
- Broad Family Coverage — Fits Genie S and SX telescopic boom lifts, the ZX-135/70 articulating boom, and GTH-1056 telehandlers, covering a wide range of Genie equipment from a single part number.
A hex head cap screw is a structural fastener that clamps two or more components together by developing a controlled clamping force when torqued to specification. On large aerial equipment, fasteners like this one are critical to keeping structural joints, mounting brackets, and mechanical assemblies secured under the dynamic loads and vibration these machines encounter in everyday operation. Using a fastener of the incorrect grade or thread specification can compromise joint integrity; replacing it with the correct genuine OEM part restores the assembly to its designed clamping load and keeps the machine operating as intended.
