Multiquip RB253046 External Lockwasher 7/8

The Multiquip RB253046 External Lockwasher 7/8 is a genuine OEM component designed for Multiquip Rebar Bender equipment. As a direct OEM replacement, this lockwasher is produced to the same specification as the original hardware, ensuring correct seating and clamping force when installed. This part is confirmed for use with the JB8090 rebar bender, making it a straightforward like-for-like swap during maintenance or repair. Sourced directly through DHS Equipment, you can order with confidence knowing you are getting the exact part your machine calls for.

Key Features

• Genuine OEM Hardware Grade — Manufactured to the original fastener specification, delivering correct tooth geometry and material hardness for dependable clamping performance on the JB8090.
• Direct Drop-In Replacement — Sized at 7/8 to match the original mounting point exactly, seating against the mating surface the same way the factory-installed washer does.
• Confirmed Fitment for JB8090 — Verified for the Multiquip JB8090 Rebar Bender, so you are not guessing on compatibility before the part ships.
• Fastener Integrity Under Load — An external lockwasher in good condition bites into the bearing surface to resist loosening under vibration and operational torque; a worn or missing washer can allow fastener back-out and component movement.
• Correct Torque Retention for Structural Connections — On rebar bending equipment, where fastener security directly affects machine rigidity and operator safety, using the correct OEM-spec lockwasher matters.

An external lockwasher works by using its serrated or tabbed outer edge to grip the mating surface and prevent a nut or bolt from rotating loose under vibration, impact, or repeated load cycles. On a rebar bender like the JB8090, mechanical stress is transmitted through the frame and working components every time a bar is bent, making fastener security critical to keeping joints tight and the machine structurally sound. A missing, deformed, or incorrect lockwasher can allow fasteners to back out over time, leading to play in critical assemblies and potentially unsafe operating conditions.
