The Genie 75091GT Socket Head Cap Screw, 3/8-16 x 4 GR 5 is a genuine OEM fastener built for the S-120 and S-125 telescopic boom lifts. Sourced directly from Genie, this screw matches the exact thread pitch, grip length, and grade specification called out in the original parts manual, ensuring a correct installation without rework. Cross-reference part number 75091GT against your machine's parts manual to confirm it is the right fastener for your application before ordering.
Key Features
- Grade 5 Tensile Strength — manufactured to GR 5 specification, delivering the clamping load and shear resistance the joint was engineered to handle.
- Exact Thread and Length Match — 3/8-16 thread form and 4-inch grip length conform to the OEM specification, so the screw seats and torques correctly the first time.
- Socket Head Drive — the SHC drive profile allows installation in confined or recessed locations where a standard hex-head wrench cannot reach.
- Confirmed S-Series Fitment — designed for S-120 and S-125 telescopic boom lifts; verify against your serial-number-specific parts manual before ordering.
- Genuine OEM Part — supplied by Genie, ensuring dimensional conformity and material grade that match the original fastener removed from your machine.
A socket head cap screw is a threaded fastener that uses an internal hex (Allen) drive to draw two or more components tightly together. The grade rating determines how much clamping force and shock load the fastener can withstand before stretching or failing — using an under-grade substitute risks joint loosening or fastener failure under the loads present on a working boom lift. When a screw of this type is stripped, broken, or missing, the joint it secures can shift or separate, affecting the structural integrity of the assembly it holds. Replacing a damaged fastener with the correct OEM-spec screw restores the joint to its intended clamping load and keeps the machine operating as designed.
