The Genie 1257248GT Socket Head Cap Screw, M4-0.7X8 is a genuine OEM fastener built for Genie S series telescopic boom lifts and Z series articulating boom lifts. Sourced directly from Genie, this screw meets the original DIN912 specification for thread form, head geometry, and material grade — ensuring it seats and torques exactly as the factory intended. Cross-reference part number 1257248GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- Genuine OEM Material Grade — Manufactured to DIN912 specification, delivering the correct alloy grade, thread pitch, and head dimensions for a secure, torque-rated installation.
- Exact Dimensional Fit — M4-0.7X8 sizing matches the original fastener, so this screw installs directly into existing threaded holes without rework or modification.
- Broad Boom Lift Coverage — Fits a wide range of Genie S series telescopic and Z series articulating boom lifts, including multiple Z-45, Z-60, Z-62, Z-80, Z-135, and ZX-135 variants, as well as S-40 and S-45 models.
- Fastener Integrity Where It Counts — A correct-spec fastener holds assemblies at the designed clamp load. An incorrect or worn screw risks loosening under vibration, which can compromise the components it secures.
- Genuine Part Assurance — Supplied as a genuine Genie OEM part, this screw carries the same part number used in Genie's own parts system, simplifying reordering and documentation.
A socket head cap screw is an internally driven fastener — tightened with a hex key rather than an open wrench — used where access is tight or a low-profile head is required. The M4-0.7X8 designation specifies a 4 mm diameter, 0.7 mm thread pitch, and 8 mm length, all of which must match the original fastener exactly for the joint to hold at the correct clamp load. Using an incorrect size or grade risks thread stripping, fastener loosening under machine vibration, and potential failure of the assembly the screw is meant to secure.
