The Genie 77677GT Phillips PHM Screw, 10-24 x 1 is a genuine OEM fastener built for a wide range of Genie vertical mast lifts, boom lifts, and related equipment. Sourced directly through Genie's OEM supply chain, this screw meets the exact dimensional and material standards called out in Genie's parts specifications. It is a direct replacement for the original hardware, covering models including the GR-12, GR-15, GR-20, GRC-12, QS series, SX-180, and Z-45/25 articulating booms. Always cross-reference part number 77677GT against your machine's parts manual to confirm it is the correct item for your specific unit.
Key Features
- Genuine OEM Dimensional Conformity — Manufactured to Genie's exact thread pitch (10-24) and length (1 inch) specifications, ensuring the screw seats and torques correctly every time.
- Direct Hardware Replacement — Installs in place of the original fastener with no modification, using a standard Phillips drive for straightforward field or shop service.
- Broad Genie Fitment — Covers Genie GR and GRC vertical mast lifts, QS stock-picking lifts, the SX-180 telescopic boom, and Z-45/25 articulating boom variants including the DC and Bi-Energy models.
- Secure Fastening Where It Counts — A correct-spec screw maintains proper clamping force on the components it secures; an undersized or mismatched fastener can work loose under vibration and lead to panel, guard, or component movement.
A Phillips PHM screw is a machine screw with a pan head and a Phillips drive recess, threaded at 10-24 (a standard coarse machine thread) and cut to a 1-inch grip length. Fasteners like this one are used throughout Genie equipment to secure panels, guards, brackets, and electrical or structural components. When a screw is stripped, corroded, or missing, the component it holds can shift or come loose during operation — replacing it with the correct OEM part restores the original clamping specification and keeps the assembly properly secured.
