The Genie 137668GT Screw, PHM, 6-19X.75, 48-2 Tri-L is a genuine OEM fastener built for Genie GS scissor lifts and the GRC-12 vertical mast lift. As a direct OEM replacement, this screw is manufactured to the exact specification Genie requires, ensuring the correct thread form, drive type, and dimensions every time. It is confirmed to fit the GS-1330m, GS-1932, GS-2032, GS-2632, GS-3232, GS-4047, GS-4655, and GRC-12. Cross-reference part number 137668GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- Genuine OEM Specification — Manufactured to Genie's exact dimensional and thread standards, so this screw seats and torques correctly without rework or shimming.
- Tri-Lobular Thread Form — The 48-2 Tri-L thread form is engineered to resist loosening under vibration, a critical property for fasteners used on mobile aerial equipment.
- Direct OEM Replacement — Matches the original fastener in drive type, thread pitch, and length, allowing straightforward installation with no modification to mating components.
- Broad Scissor Lift Fitment — Confirmed for multiple GS scissor lift models including the GS-1330m, GS-2632, GS-3232, GS-4047, and GS-4655, as well as the GRC-12.
- Structural Integrity — Using the correct OEM fastener maintains the clamping load the original design specifies; substituting an incorrect screw risks joint loosening or component damage over time.
A PHM screw — pan head machine screw — is a threaded fastener used to secure components in precise, repeatable assemblies. The pan head profile distributes clamping load across a wider bearing surface than a countersunk head, making it well suited to fastening panels, brackets, and covers where a flush finish is not required. The 48-2 Tri-L designation refers to a tri-lobular thread form that cuts its own mating thread on installation, creating a tight interference fit that resists vibration-induced loosening. When a fastener of this type is missing, stripped, or substituted with an incorrect size, the joint it holds can shift or separate, leading to component misalignment or accelerated wear on surrounding parts.
