As an authorized Multiquip OEM part, the part delivers the exact thread specification and material grade required to maintain secure, accurate fastening in your rebar bending equipment. DHS Equipment supplies this part direct, so you can trust you are receiving the correct component for your machine.
Key Features
- Exact Thread Specification: — Manufactured to the precise 5/8-18 fine-thread standard, ensuring correct torque retention and thread engagement on the fastening point it secures.
- Genuine OEM Construction: — Produced to Multiquip's original material and hardness requirements, matching the locking force and wear characteristics of the factory-installed nut.
- Broad Rebar Bender Compatibility: — Confirmed fitment across the JB5090, JB7090, JB7135, JB8090, JB9180, JB11090, JB5135, and JPU1 rebar bender models.
- Direct Swap Installation: — Drops in as a straight replacement using standard tooling — no thread chasing or modification to the mating fastener required.
- Maintains Bending Accuracy: — A properly secured lock nut prevents component shift during bending cycles, keeping bend angles consistent and protecting the drive assembly from play-induced wear.
- Operator Safety Assurance: — Lock nuts on rebar bending equipment bear significant cyclic load; using the correct OEM-spec nut prevents loosening under repeated stress, reducing the risk of unexpected mechanical failure during operation.
A lock nut is a fastener engineered to resist loosening under vibration and repeated mechanical load. On rebar bending equipment, lock nuts secure critical rotating and structural components that experience significant cyclic stress with every bending cycle. When a lock nut wears, strips, or loosens, it allows movement in the assembly it secures — leading to imprecise bends, accelerated wear on adjacent components, and the potential for sudden mechanical failure. Replacing a worn or damaged lock nut promptly keeps the bender running accurately and safely.
