The Multiquip RB252821 is a genuine OEM Hex Cap Screw (7/8-14 x 3-1/4 Lg) designed for Multiquip rebar bender models including JB5135, JB5090, JB8090, JB9180, JPU1, JB7135, JB7090, and JB11090. As a factory-sourced fastener, RB252821 is manufactured to the exact thread pitch, length, and grade specifications required by these machines. Sourcing the correct hex cap screw matters on rebar bending equipment where fastener integrity directly affects structural rigidity and operator safety. DHS Equipment stocks this genuine OEM component so you can get your machine back in service with confidence.
Key Features
- Correct Thread and Length Specification — Machined to a 7/8-14 fine thread pitch at 3-1/4 inches in length, matching the exact fastener specification used in Multiquip JB and JPU series rebar benders.
- Genuine OEM Sourcing — Produced by Multiquip to the same grade and hardness requirements as the original fastener, ensuring proper clamp load and torque retention under high-cycle bending loads.
- Broad JB Series Compatibility — Confirmed fitment across JB5090, JB5135, JB7090, JB7135, JB8090, JB9180, JB11090, and JPU1 rebar benders in a single part number.
- Structural Integrity Under Load — On rebar bending equipment, under-spec or worn fasteners can allow critical assemblies to shift during operation; using the correct OEM-grade screw maintains the tight tolerances these machines depend on.
- Operator Safety Compliance — Rebar benders generate substantial mechanical force; a fastener of the correct grade and dimensions is essential to prevent joint failure or component movement during bending cycles.
A hex cap screw is a externally threaded fastener with a hexagonal head designed to be driven by a wrench, providing high clamping force when torqued to specification. On rebar bending equipment, hex cap screws are used to secure structural joints, pivot assemblies, and frame components that must withstand repeated high-force bending cycles. When a fastener stretches, strips, or is substituted with an incorrect thread pitch or grade, joint looseness can develop quickly, leading to misalignment, accelerated wear on surrounding components, or unsafe machine operation.
