Key Features
- Genuine OEM Hardware Grade — Manufactured to the exact material hardness and tooth geometry specified for Multiquip rebar bender fastener assemblies, ensuring proper locking force without distortion under load.
- Direct-Fit Replacement — The 5/8" sizing matches the original fastener positions on JB-series and JPU1 machines, dropping in without any modification to mounting hardware or fastener stacks.
- Broad JB-Series Compatibility — Confirmed fitment across JB5090, JB5135, JB7090, JB7135, JB8090, JB9180, JB11090, and JPU1 Rebar Benders, covering the full range of Multiquip JB-family models.
- Prevents Fastener Loosening Under Vibration — Rebar benders generate significant cyclic stress during operation; a serviceable external lockwasher maintains clamp load and prevents critical fasteners from backing out during heavy bending cycles.
- Exact Part Number Match — Ordering by Multiquip part number RB252831 eliminates fitment guesswork and ensures you receive the correct washer for your specific machine configuration.
An external lockwasher works by biting into the mating surfaces of a bolt head or nut and the workpiece, creating mechanical resistance that prevents the fastener from rotating loose due to vibration or dynamic loading. On rebar benders, where repeated high-torque bending cycles put constant stress on the machine frame and mechanical assemblies, keeping fasteners properly secured is essential to both accurate operation and operator safety. A worn, flattened, or missing lockwasher allows fasteners to gradually loosen, which can lead to misalignment of bending components or unexpected mechanical failure during use.
