Key Features
- Genuine OEM Fastener Grade — Manufactured to the exact thread pitch, hardness grade, and dimensional tolerances specified for Multiquip equipment, ensuring secure clamping force at every installation point.
- Drop-In Replacement — Matches the original hardware specification thread-for-thread, so installation requires no reworking of mating components or fastener seats.
- Broad Cross-Equipment Compatibility — Fits concrete pumps (LS and C-series), Whiteman and Essick mixers, WTB and WBH power buggies, AR and V-series rollers, and QP/MQ trash pumps — a single part number across the Multiquip lineup.
- Structural Integrity Where It Counts — A correctly torqued, specification-correct hex nut maintains critical joint integrity; an incorrect or worn fastener can allow component loosening, vibration damage, or structural failure under load.
- Verified Part Number — Sold as Multiquip 2105164 through DHS Equipment, an authorized distributor — you receive the correct OEM part with full traceability back to the manufacturer.
A hex nut is a six-sided threaded fastener used in conjunction with a bolt or threaded stud to clamp two or more components securely together. In heavy construction equipment, hex nuts are critical to maintaining structural connections, mounting hardware, and panel or guard assemblies that are subject to continuous vibration and mechanical load. When a hex nut is the wrong grade, stripped, or missing, the joint it secures can work loose over time, leading to accelerated wear on surrounding components or an unsafe operating condition. Using the correct OEM-specified nut — with the right thread class and hardness rating — ensures the joint holds to its design specification for the service life of the assembly.
