As a direct OEM replacement, this lock nut meets the original dimensional and material specifications Genie requires. Cross-reference part number 12012GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- Genuine OEM Specification — manufactured to Genie's original dimensional and thread standards for a consistent, correct fit every time.
- 3/8-16 Thread Sizing — the 3/8-16 thread callout is the identity of this fastener; it installs directly in any position calling for this specification without modification.
- Locking Retention — the lock nut design resists loosening under vibration and operational load, maintaining secure connections at fastened joints.
- Broad Equipment Compatibility — fits AL and RL series light towers, GS scissor lifts, AWP personnel lifts, and a range of Genie material lifts and winch models.
- Long Service Life — OEM material grade ensures the nut holds its thread engagement over repeated service cycles, reducing the need for premature fastener replacement.
A lock nut is a threaded fastener designed to resist self-loosening when the assembly it secures is exposed to vibration, movement, or dynamic load. Unlike a standard nut, the locking mechanism — whether a nylon insert, distorted thread, or prevailing-torque feature — creates resistance that keeps the nut seated at the specified torque. When a lock nut fails or is replaced with an incorrect size, the joint it holds can work loose, leading to misalignment or component separation. Using the correct OEM part, sized precisely to the 3/8-16 specification, ensures the joint maintains its integrity throughout normal service intervals.
