The Genie 1257721GT is a genuine OEM Hex Head Flange Screw, 3/8-16 x.75 built for the Genie S-85 XC telescopic boom lift and GTH-1056 telehandler. As a factory-sourced fastener, this screw meets Genie's original dimensional and material specifications, ensuring a direct replacement with no guesswork. Cross-reference part number 1257721GT against your machine's parts manual to confirm it is the correct fastener for your specific application before ordering.
Key Features
- Genuine OEM Dimensional Conformity — Manufactured to Genie's original thread pitch, shank length, and grade specifications, so the screw seats and torques correctly the first time.
- Flange Head Design — The integrated flange distributes clamping load across a wider bearing surface, reducing the need for a separate washer and maintaining consistent joint integrity.
- Correct Thread Specification — 3/8-16 coarse thread and .75 in length are the exact callout for this position; substituting an incorrect size risks under-clamping or thread damage in the parent material.
- Verified Fitment — Confirmed for the Genie S-85 XC telescopic boom and GTH-1056 telehandler, covering both aerial lift and telehandler applications.
A hex head flange screw combines a standard hex-drive head with a wide, washer-style flange formed as part of the head itself. This flange spreads the clamping force over a larger surface area than a plain hex head, helping to prevent the fastener from pulling through or deforming softer mounting surfaces. When a fastener of this type loosens, works free, or is replaced with an incorrect grade or size, the joint it secures can shift, vibrate, or fail to hold torque — leading to component movement or damage. Using the correct OEM screw with the right thread specification, grade, and coating ensures the joint performs as Genie designed it.
