Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the exact 1/2-13 thread pitch and 1.25-inch length specified for these Genie machines, ensuring correct engagement and clamp load.
- Direct Bolt-In Replacement — Matches the original socket head profile, allowing installation with a standard hex key without any modification to the mounting location.
- Broad Z and TMZ Coverage — Fits multiple Genie articulating boom lift and trailer-mounted boom variants, including the Z-34/22 and TMZ-50/30 families.
- Structural Integrity at Every Joint — A correctly torqued, properly dimensioned fastener maintains the clamping force that keeps structural and mechanical connections secure across the machine's range of motion.
- Sourced from Genie — Supplied as a genuine Genie OEM part through DHS Equipment, so the specification, material grade, and thread form are exactly what the machine was built with.
A socket head cap screw is a high-strength fastener used throughout the structural and mechanical assemblies of aerial equipment. Its recessed hex socket drive allows it to be seated in tighter spaces than a standard bolt head, and the cylindrical profile provides a clean, low-profile fit against mating surfaces. When a fastener of this type is worn, cross-threaded, or missing, the joint it secures can loosen under load or vibration — leading to play in components that are designed to remain fixed. Replacing a damaged or missing screw with the correct OEM part, torqued to specification, restores the connection to its original condition.
