The Multiquip RB252830 is a genuine OEM External Lockwasher (1/2") designed for Multiquip rebar bender models including JB5090, JB7090, JB7135, JB8090, JB9180, JB11090, JB5135, and JPU1. As a factory-sourced component, the part meets the same specifications as the original hardware used in production, ensuring a true drop-in replacement with no guesswork. Sourced directly through Multiquip's OEM parts program, this lockwasher is the right call when accuracy and fastener security matter.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the same material and dimensional tolerances as the original fastener, maintaining the clamping integrity required in rebar bending applications where torque loads are significant.
- External Tooth Design for Secure Fastening — The external tooth profile bites into the mating surface under load, resisting loosening from vibration and repeated bending cycles that are common in rebar bender operation.
- Broad Rebar Bender Compatibility — Fits JB5090, JB5135, JB7090, JB7135, JB8090, JB9180, JB11090, and JPU1 models, covering the full range of Multiquip JB-series and JPU rebar benders.
- Direct Reinstallation — Matches the original 1/2" specification exactly, slotting into existing bolt assemblies during routine maintenance or fastener replacement without the need for sizing adjustments.
- Critical for Structural Joint Integrity — A worn or missing lockwasher on a rebar bender can allow fasteners to back out under load, compromising the machine's frame and bending arm connections — this OEM part restores that holding force correctly.
An external lockwasher is a small but essential piece of hardware in any bolted joint that experiences dynamic loading or vibration. Its serrated outer teeth grip the contact surface as the fastener is tightened, creating resistance that prevents the bolt or nut from loosening over time. On rebar benders like the JB-series machines, where significant mechanical force is applied repeatedly through bending cycles, maintaining fastener torque across all joints is critical to safe and accurate operation. A missing or damaged lockwasher allows fasteners to gradually back out, which can lead to loosened assemblies, misalignment, or unsafe machine conditions.
