The Genie 218456GT Hex Head Cap Screw, M12X70, DIN931, 10.9, Y is a genuine OEM fastener built for Genie SX telescopic boom lifts and ZX articulating boom lifts. As a direct OEM replacement, this screw is manufactured to the same DIN931 standard and 10.9 property class specified in the original Genie parts manual, ensuring it meets the structural demands of heavy-duty aerial lift applications. Compatible models include the SX-150, SX-180, SX-135 XC, SX-125 XC, SX-105 XC, and ZX-135/70 — cross-reference part number 218456GT against your machine's parts manual to confirm the correct application before ordering.
Key Features
- Grade 10.9 Strength Rating — Manufactured to DIN931 specification at property class 10.9, delivering the high tensile strength required for structural fastening on large boom lift assemblies.
- Genuine OEM Part — Sourced directly through Genie's OEM supply chain, this screw carries the same part number, thread pitch, and dimensional spec as the original hardware installed at the factory.
- Exact-Thread Replacement — M12X70 sizing and DIN931 partial-thread form ensure this fastener installs directly into existing threaded bosses and hardware points without rework or modification.
- Broad SX and ZX Fitment — Fits the SX-105 XC, SX-125 XC, SX-135 XC, SX-150, SX-180, and ZX-135/70 — covering Genie's largest telescopic and articulating boom platforms.
- Structural Integrity at Height — A correctly rated fastener keeps critical assemblies torqued and secure during lift operations. Substituting an underrated or incorrect-grade screw risks joint failure under load.
A hex head cap screw is a threaded fastener used to clamp or secure structural components together, driven with a wrench or socket on the six-sided head. The DIN931 designation specifies a partially threaded shank, which is important in applications where the unthreaded portion must pass through a clearance hole before engaging a nut or threaded bore. The 10.9 property class indicates a high-strength steel fastener with defined minimum tensile and yield strength values — using a lower-grade substitute in the same application can result in fastener stretch, loosening, or failure under the loads these large boom lifts generate.
