Key Features
- Stainless Steel Construction — The SS designation confirms a stainless steel fastener, offering strong resistance to corrosion and surface degradation in demanding jobsite environments.
- Exact OEM Dimensions — The 3/8-16 x .75 thread and length specification matches the original Genie part, ensuring proper seating and torque without modification.
- Button Head Socket Drive — The low-profile button head and hex socket drive allow installation in areas where clearance is limited, maintaining access without sacrificing holding strength.
- Direct Replacement for S-Series Booms — Confirmed fit for the S-80X, S-80, and S-85 telescopic boom lifts, so there is no guesswork when sourcing a like-for-like swap.
- Genuine OEM Part — Supplied by Genie, this fastener meets the same dimensional and material standards as the screw it replaces, keeping your machine properly assembled.
A button head socket cap screw combines a low-profile domed head with a hex socket recess, making it well suited to assemblies where a standard bolt head would protrude too far or interfere with surrounding components. The 3/8-16 thread pitch and .75-inch length are specific to the joint it fastens — using an incorrect size risks under-engagement of the threads, which can lead to a loose or failed connection. Replacing a worn, stripped, or corroded screw with the correct OEM fastener restores the integrity of the fastened joint and keeps the assembly performing as intended.
