The Multiquip 511910 Bolt 1/4" NC x 1-1/4" G5 is a genuine OEM fastener designed for Essick and Whiteman plaster and mortar mixer series, including EM70, EM90, EM120, WM70, WM90, and WM120 models. Sourced directly from Multiquip, this Grade 5 bolt meets the exact torque and dimensional specifications required for correct assembly and safe operation. Using the correct OEM hardware ensures that critical mixer components stay properly secured under the vibration and load cycles these machines experience daily. Confirm your model code against the fitment list to ensure 511910 is the right bolt for your application.
Key Features
- Grade 5 Tensile Strength — Rated G5 for the clamping force and shear resistance required in mixer assemblies subject to continuous vibration and mechanical stress.
- Exact Thread Specification — 1/4" NC (National Coarse) thread form installs directly into threaded receiver points on Essick and Whiteman mixer frames with no rethreading or modification.
- Broad Mixer Fitment — Compatible across EM70, EM90, EM120, WM70, WM90, and WM120 series mixers, covering both steel and plastic drum variants as well as Honda and LF-powered configurations.
- OEM Hardware Consistency — As a genuine Multiquip part, 511910 matches the original bolt used at the factory, ensuring proper joint integrity and consistent torque values across your repair.
- Prevents Fastener Mismatch Risk — Substituting incorrect grade or thread-pitch bolts in mixer assemblies can lead to loosening, component misalignment, or fastener failure — using the specified OEM bolt eliminates that risk.
A bolt of this specification serves as a structural fastener that clamps and secures components within the mixer assembly — from drum hardware and drive covers to frame-mounted brackets. In a mortar or plaster mixer, fasteners are constantly exposed to vibration transmitted through the drum and drivetrain, which can cause underspec or mismatched hardware to back out or fail prematurely. Keeping the correct grade and thread-pitch bolt in place ensures that all attached components remain properly aligned and torqued throughout the mixer's service life.
