Genie 1255802GT Hex Head Flange Screw, 1/2-13x2.5, Grade 8, Zinc

The Genie 1255802GT is a genuine OEM Hex Head Flange Screw, 1/2-13x2.5, Grade 8, Zinc built for a wide range of Genie equipment including GTH telehandlers, S and SX telescopic boom lifts, Z articulating boom lifts, and the RL4 vertical mast lift. As a direct OEM replacement, this screw is manufactured to Genie's specifications for thread pitch, grade, and finish, so it installs correctly without modification. Cross-reference part number 1255802GT against your machine's parts manual to confirm it is the right fastener for your application before ordering.

Key Features

• Flange Head Design — The integrated flange distributes clamping load over a wider surface area, reducing the risk of fastener pull-through and eliminating the need for a separate washer in most applications.
• Exact Thread Specification — A 1/2-13 thread pitch and 2.5-inch length match the OEM specification precisely, ensuring correct engagement and torque retention in the mating component.
• Broad Genie Fitment — Fits GTH telehandlers, S-65 XC, S-85 XC, SX-125 XC, Z-45 DC, Z-62/40, Z-80/60, RL4 vertical mast, and additional Genie platforms — confirm fitment via your parts manual.
• Genuine OEM Part — Supplied as a genuine Genie OEM component, this screw meets the dimensional and material requirements of the original design with no substitution or compromise.

A hex head flange screw combines a standard hex drive head with a wide, integrated flange that acts as a built-in washer. This design spreads the clamping force across a broader contact area, which protects mating surfaces and maintains joint integrity under vibration and load — conditions common in aerial lift and telehandler operation. When a fastener in this position loosens, stretches, or corrodes, the joint it secures can shift or fail, creating the potential for component damage or unsafe machine behavior. Replacing a worn or damaged screw with the correct OEM part restores the joint to its designed clamping specification and helps maintain the structural integrity of the assembly it secures.
