As a direct OEM replacement, RB252833 is manufactured to the exact thread specification — 3/8-24 unified fine thread — ensuring a correct, secure fit with no guesswork at installation. This is the same part supplied on new machines, so you can trust it to hold adjustment settings and maintain the mechanical integrity of your bender's fastening points. DHS Equipment stocks this genuine Multiquip component so you can get your machine back to work fast.
Key Features
- Exact Thread Specification: — Cut to 3/8-24 unified fine thread — the correct pitch for the fastening points on Multiquip rebar benders, ensuring full thread engagement and secure clamping force.
- Genuine OEM Construction: — Sourced directly from Multiquip, this jam nut meets the same material hardness and dimensional tolerances as the original hardware, preventing stripping or backing-off under repeated operational loads.
- Broad Rebar Bender Compatibility: — Confirmed fitment across the JB5090, JB5135, JB7090, JB7135, JB8090, JB9180, JB11090, and JPU1 rebar bender series.
- Maintains Adjustment Lock Integrity: — A worn or damaged jam nut allows critical settings to drift during operation; replacing with this part restores the locking function that keeps bending angles consistent and repeatable.
- Direct Service Replacement: — Installs in place of the original hardware without modification, making it a straightforward field or shop repair for any technician.
A jam nut is a thin locking nut threaded against a primary nut or fastener to prevent it from loosening due to vibration or repeated mechanical load. On rebar benders, jam nuts are used to lock adjustment points — such as stop bolts and angle-setting mechanisms — so that bend angles remain consistent throughout a job. When a jam nut becomes stripped, cracked, or insufficiently torqued, those settings can shift mid-operation, leading to inaccurate bends and potential rework. Replacing a damaged jam nut promptly with the correct OEM part restores the machine's ability to hold precise, repeatable settings.
