Multiquip 10133 Nyloc Nut 3/8-16

The Multiquip 10133 is a genuine OEM Nyloc Nut 3/8-16 used across an exceptionally wide range of Multiquip and affiliated brand equipment, including walk-behind and ride-on trowel families (HHN, HTN, HTX, STX, JWN, LD, MD series), Whiteman mixers (WM120), Essick mixers (EM120), pavement and masonry saws (SP, PS, MP, MS series), light towers (LT12, MLT25DCA), trash pumps (MQ62TDH, QP4TKT), generators (DCA20SPXU2, DAC7000SS), water trailers (WT5C, WTE5C), and roller screeds (WRSPUDF, WRS5200). As a genuine OEM component sourced directly from Multiquip, part number 10133 meets the exact dimensional and material specifications called out in the original equipment build. This nyloc nut is a critical fastener stocked for service and assembly across the full Multiquip portfolio, making it an essential item for any dealer, service center, or fleet operator running multiple machine types.

Key Features

• Genuine OEM Nylon-Insert Lock Design — The nylon collar deforms against the thread under torque, creating a mechanical resistance to loosening that standard hex nuts cannot provide in vibration-heavy applications.
• 3/8-16 Thread Specification — UNC 3/8-16 threading matches the fastener standard used throughout Multiquip's equipment assemblies, allowing direct installation with standard 9/16 in. tooling and no thread chasing required.
• Broad Cross-Equipment Compatibility — A single part number covers trowels, mixers, saws, light towers, pumps, generators, screeds, and trailers across the Multiquip, Whiteman, Essick, and STOW product lines.
• Vibration Resistance Where It Counts — Equipment like plate compactors, saws, and trowels subject fasteners to continuous vibration cycles; the nyloc insert maintains clamping load and prevents joint loosening between service intervals.
• OEM Part Number Traceability — Ordering by Multiquip part number this part ensures the correct grade, insert material, and finish are supplied, eliminating substitution errors when servicing multiple machine families.

A nyloc nut — also called a nylon-insert lock nut — is a standard hex nut fitted with a nylon collar at the top of the nut body. When threaded onto a bolt or stud, the nylon insert is deformed by the threads, creating a friction-based locking force that resists loosening caused by vibration, shock loads, and thermal cycling. Unlike chemical thread-locking compounds, a nyloc nut provides immediate mechanical resistance and can be removed and reinstalled with standard hand tools. When a nyloc nut wears out or is over-torqued and the nylon insert loses its grip, the fastened joint can work loose, leading to misalignment, component damage, or unsafe operating conditions — particularly on rotating assemblies and structural mounting points common across Multiquip's trowel, saw, and pump equipment families.
