Key Features

• Genuine OEM Fastener Grade — Manufactured to Multiquip's exact thread pitch and torque retention specifications for the 1/2-20 application, so it holds firm under the cyclic loading that rebar bending puts on fastened joints.
• Drop-In Replacement — Matches the original mounting position and thread engagement length, allowing straightforward installation without additional hardware or modification.
• Broad Rebar Bender Compatibility — Fits JB5135, JB7135, JB7090, JB9180, JB5090, JB8090, JB11090, and JPU1 models, covering a wide range of Multiquip rebar bending equipment.
• Vibration-Resistant Locking Design — The locknut's prevailing torque feature resists self-loosening caused by machine vibration and repeated bending cycles, maintaining structural integrity of the assembly over time.
• Prevents Costly Assembly Failure — A worn or missing locknut can allow critical fastened joints to loosen during operation, leading to misalignment or component damage — replacing it promptly keeps the bender performing as intended.

A locknut is a threaded fastener engineered to resist loosening under vibration and dynamic loads. Unlike a standard nut, it incorporates a locking mechanism — typically a distorted thread or nylon insert — that creates resistance against rotation once torqued into position. In a rebar bender, locknuts secure key structural and mechanical components that are subjected to significant bending forces and repetitive stress cycles. When a locknut loosens or fails, it can compromise the alignment and integrity of the assembly, increasing wear on surrounding components and creating a potential safety concern during operation.
