The Multiquip EM492313 is a genuine OEM 3/8" x 1-1/2" NC Grade 5 Bolt designed for a wide range of Multiquip Power Buggies, concrete mixers, and mortar mixers. This fastener is a direct OEM replacement sourced from Multiquip, ensuring correct thread specification, grip length, and tensile rating for the original application. Confirmed fitment includes Power Buggy models WTB-16PD, WBH-16, WBH-16E, WBH-16F, WBH-16EF, WBH-16EAW, WBH-16EAWDF, and WBH21EPA, as well as mixer models MC64SK, MC64PK, MC64P/S, WM70S/P, WM90S/P, EM70P/S, and EM90P/S. Keeping the correct fastener in place is critical to maintaining structural integrity across frames, guards, and mechanical assemblies on this equipment.
Key Features
- Grade 5 Tensile Strength — Medium-carbon steel construction meets SAE Grade 5 tensile requirements, providing the clamping force needed for structural and mechanical fastening points on heavy-use equipment.
- Correct Thread Form and Length — 3/8"-16 NC (coarse thread) at 1-1/2" grip length matches OEM hole patterns and thread engagement specs exactly as installed at the factory.
- Broad Cross-Family Fitment — Verified for use across Multiquip Power Buggies (WTB-16PD, WBH-16 series, WBH21EPA) and concrete and mortar mixers (MC64, WM70, WM90, EM70, EM90 series).
- Genuine OEM Part — Sourced directly from Multiquip as part number EM492313, so you get the correct grade, finish, and dimensions without guesswork or substitution risk.
- Structural Reliability — A worn, stripped, or incorrect-grade bolt at a critical fastening point can lead to component loosening or failure under load — replacing with the correct OEM spec restores full joint integrity.
A Grade 5 hex bolt is a structural fastener used to clamp and secure components together at joints, brackets, frames, and mechanical mounting points. The grade rating determines the bolt's tensile and proof load strength — Grade 5 is a step above common hardware-grade fasteners and is specified by equipment manufacturers where higher clamping force and resistance to loosening under vibration are required. When a bolt is the wrong grade, undersized, or has a worn thread, the clamped joint can shift, loosen, or fail during operation, creating safety risks and accelerating wear on surrounding components. Using the correct OEM-specified fastener like the Multiquip EM492313 ensures the joint performs as designed throughout the service life of the machine.
