The Multiquip 511526 is a genuine OEM HHCS Screw 1" NC x 8 designed for EM120, EM120P Series, EM120S Series, WM120PH, and WM120SH plaster and mortar mixers. As a factory-sourced fastener, it matches the exact thread pitch, grade, and dimensional spec of the original hardware used in production. This screw is a direct replacement for the 511526 position in your mixer's assembly, ensuring correct clamping load and structural integrity throughout the drivetrain or frame connection it secures. If you're performing routine maintenance or rebuilding a worn assembly, sourcing the correct OEM fastener is a straightforward way to ensure the repair holds up under working loads.
Key Features
- OEM-Grade Fastener Material — Sourced directly from Multiquip, this screw meets the same thread class and tensile grade as the hardware originally installed at the factory.
- Correct Thread Specification — Cut to 1" NC (National Coarse) x 8 threading, this screw seats and torques correctly without chasing threads or forcing fit.
- Confirmed Fitment — Compatible with EM120, EM120P Series, EM120S Series, WM120PH, and WM120SH Essick and Whiteman mixer models.
- Structural Integrity Under Load — Mixers operate under continuous rotational stress; using the correctly graded fastener prevents joint loosening, fatigue failure, and progressive component damage.
- Hex Head Cap Screw Design — The HHCS format allows standard wrench or socket installation, making replacement straightforward during scheduled service or field repairs.
A hex head cap screw (HHCS) is a structural fastener used to clamp and secure machine components — such as drive assemblies, gear housings, frames, and guards — under specified torque. In mixer applications, fasteners like the 511526 are subject to vibration and cyclic loading during every batch cycle. When a fastener stretches, strips, or is replaced with an incorrect grade or thread pitch, the joint can lose clamping force, allowing movement between components that accelerates wear or causes assembly failure. Using the correct OEM-spec replacement ensures the connection is restored to its designed holding strength.
