Multiquip RB252837 Locknut (3/8-24)

The Multiquip RB252837 Locknut (3/8-24) is a genuine OEM fastener designed for Multiquip rebar bender models including JB5090, JB7090, JB7135, JB8090, JB9180, JB11090, JB5135, and JPU1. As a factory-sourced component, it meets the exact thread specification and torque retention requirements of the original hardware used in production. Sourcing the correct locknut matters — an improperly rated or mismatched fastener can back off under the vibration and cyclic loads typical of rebar bending operations, compromising both the machine's structural integrity and operator safety.

Key Features

• Thread-Matched Fastener: — Manufactured to the 3/8-24 UNF fine-thread standard, matching the original fastener specification used on Multiquip rebar benders for a secure, torque-resistant installation.
• Genuine OEM Component: — Sourced directly from Multiquip, this locknut carries the same material grade and locking feature as the part installed at the factory — no substitution required.
• Broad Rebar Bender Compatibility: — Confirmed fitment across JB5090, JB5135, JB7090, JB7135, JB8090, JB9180, JB11090, and JPU1 rebar bender models.
• Vibration-Resistant Locking Action: — The locking feature resists loosening under the repetitive stress and vibration generated during rebar bending cycles, helping maintain clamp load over time.
• Structural Safety Relevance: — Locknuts in rebar bending equipment secure load-bearing assemblies; using the correct OEM-spec hardware is essential to maintaining safe operating conditions for the operator.

A locknut is a threaded fastener engineered to resist self-loosening under vibration, shock loads, and cyclic stress — conditions that are common in rebar bending equipment during normal operation. Unlike a standard hex nut, the locking mechanism (whether a nylon insert, distorted thread, or prevailing-torque design) maintains clamping force even as the machine flexes and works through repeated bends. When a locknut wears, loses its locking torque, or is replaced with an incorrect grade or thread pitch, the assembly it secures can work loose, leading to misalignment, accelerated wear on surrounding components, or an unsafe condition for the operator.
