The Genie 16439GT is a genuine OEM Flat Head Socket Screw, 3/8-16 x 1, built for a wide range of Genie telescopic boom lifts, articulating boom lifts, scissor lifts, and the Superlift Advantage material lift. As a direct OEM replacement, this screw meets Genie's original dimensional and material standards, so it seats correctly without rework or shimming. Compatible models include S-series telescopic booms such as the S-40, S-60, S-65, S-80, S-80X, S-85, and S-45; Z-series articulating booms including the Z-45/22 MP and Z-60/34; and GS scissor lifts including the GS-2046, GS-2646, GS-3246, GS-3384, GS-3390, GS-4390, and GS-5390 — as well as the TZ-34/20 trailer-mounted boom. Always cross-reference part number 16439GT against your machine's parts manual to confirm it is the correct item for your unit.
Key Features
- Genuine OEM Dimensional Conformity — Manufactured to Genie's exact thread pitch, head profile, and socket drive spec so the screw engages cleanly and torques to the correct value without stripping.
- Direct Drop-In Replacement — The 3/8-16 x 1 flat head socket configuration matches the original fastener, allowing straightforward installation with a standard hex key.
- Broad Genie Fitment — Fits S-series telescopic booms, Z-series articulating booms, GS scissor lifts, the TZ-34/20 trailer boom, and the Superlift Advantage across a wide range of configurations.
- Secure Clamping Force — A correctly sized and properly torqued screw maintains structural integrity at the joint it fastens; a stripped, cross-threaded, or undersized substitute can work loose under vibration and stress cycles typical of aerial-lift operation.
- Flush Seating Profile — The flat head socket design sits flush with or below the mating surface, preventing interference with adjacent components or guards where clearance is limited.
A flat head socket screw uses a countersunk head profile that sits flush with or recessed into the mating surface, secured by an internal hex drive. This profile is chosen in assembly locations where a protruding fastener head would create clearance issues or interfere with moving parts. When a screw of this type becomes stripped, corroded, or damaged, the joint it holds can shift or loosen, which may affect the structural rigidity of the assembly and lead to accelerated wear on surrounding components. Replacing a damaged fastener promptly with the correct OEM part restores the joint to its intended holding strength.
