The Multiquip RB253081 is a genuine OEM Cap Screw 3/4-16 x 2-1/2 Long Shank designed for Multiquip JB Series rebar benders, including the JB5135, JB5090, JB7090, JB7135, JB8090, JB9180, JB11090, and JPU1. As a factory-sourced fastener, the part meets the exact thread specification, shank length, and grade requirements called out in the original Multiquip engineering documentation. Confirming compatibility with your model before ordering is straightforward — the JB series model code appears on the machine nameplate and in your parts manual. Stock this cap screw as a service spare and you will have the correct fastener on hand whenever scheduled maintenance or an unplanned repair requires it.
Key Features
- Correct Thread Form and Grade — Manufactured to the 3/4-16 UNF thread standard at the precise grade specified for structural fastener locations on JB Series rebar benders, ensuring full thread engagement without cross-threading risk.
- Extended Long Shank Design — The 2-1/2 in. long shank length matches the grip range of the original installation point, so the fastener seats and torques correctly without bottoming out or leaving insufficient thread engagement.
- Direct OEM Replacement — Sourced directly from Multiquip, part number this part matches the original build specification and drops into the same mounting location without modification to surrounding hardware or structure.
- Broad JB Series Compatibility — A single part number covers multiple rebar bender models including the JB5090, JB5135, JB7090, JB7135, JB8090, JB9180, JB11090, and JPU1, making it a practical stocking fastener for fleets running mixed JB equipment.
- Structural Integrity Under Bending Load — Rebar benders place cyclic mechanical stress on frame and pivot fasteners during every bend cycle; using the specified cap screw maintains clamping force and prevents joint movement that leads to accelerated wear of mating components.
A cap screw at a structural or pivot joint on a rebar bender does more than hold components together — it maintains the precise alignment and clamping force that allow the bending mechanism to operate accurately and safely under repeated load. On JB Series machines, fasteners at key joints are sized and graded to handle the torsional and shear forces generated during the bending cycle. When a cap screw stretches, loosens, or is replaced with an incorrect fastener, joint movement introduces play into the mechanism, which accelerates wear on mating surfaces and can cause the bending assembly to shift out of calibration. Installing the correct Multiquip RB253081 Cap Screw 3/4-16 x 2-1/2 Long Shank restores the joint to its original clamping specification and keeps the bender performing consistently bend after bend.
