Key Features
- Grade-Rated Fastener Integrity — Supplied to GR A specification, confirming the load rating and material grade required for this mounting position on the TMZ-50/30.
- Correct Thread Form — 3/4-16 fine-thread specification matches the mating hardware exactly, ensuring full thread engagement without cross-threading or rework.
- Locking Design — The lock nut construction resists loosening under vibration and cyclic loading, helping fastened joints stay torqued to spec over the machine's service life.
- Genuine OEM Part — Sourced directly from Genie, this fastener carries the same part number called out in the original assembly drawing, eliminating guesswork on grade and dimensions.
- TMZ-50/30 Fitment Verified — Confirmed for the Genie TMZ-50/30 trailer-mounted articulating boom.
A lock nut is a fastener designed to resist self-loosening when the joint is exposed to vibration, dynamic loads, or repeated movement. On a trailer-mounted articulating boom like the TMZ-50/30, structural and mechanical joints are subject to road vibration during transport and cyclical stress during operation, making the locking function of this nut critical to joint integrity. A lock nut that has stripped threads, lost its locking torque, or been replaced with an incorrect grade can allow a fastened joint to work loose over time, which may lead to misalignment, accelerated wear on adjacent components, or a joint failure that takes the machine out of service.
