Key Features
- Exact-Thread Replacement — 1-8 thread pitch and 7.8-inch length match the original fastener precisely, so the screw seats and torques correctly without rework or shimming.
- Broad Genie Fitment — Compatible with the S-80 XC and S-85 XC telescopic boom lifts as well as GTH-844, GTH-1056, and GTH-1256 telehandlers, making it a practical stocking part across multiple machine types.
- Structural Fastening Integrity — A correctly torqued, properly graded screw maintains the clamping force that holds structural and mechanical joints together. A stripped, corroded, or incorrect-grade fastener can allow joint movement and accelerate component wear.
A hex head cap screw is a threaded fastener used to clamp two or more components together, typically driven with a wrench or socket against a mating nut or tapped bore. The hex head allows high torque to be applied, creating the clamping force that keeps assembled joints rigid and secure under load and vibration. The ZAG finish on this screw provides a layer of corrosion protection that is especially important on equipment exposed to the elements over long service cycles. When a fastener corrodes, stretches, or is replaced with an incorrect grade or thread pitch, the joint can lose clamping force, leading to looseness, accelerated wear on surrounding components, or structural failure at that joint. Using the correct OEM-specification screw ensures the joint performs as designed throughout the machine's service life.
