The Multiquip 961045 SHSS 5/16-18 X 1/2" Nyloc is a genuine OEM fastener designed for a wide range of Multiquip and Essick mixing and fireproofing equipment, including MG30, EM12M, MC44SH, MC44SE, CMS-44S, and WM120PM series machines. As a direct OEM replacement, 961045 delivers the exact thread specification and nylon locking insert geometry required to maintain correct clamp load across Multiquip mixer and pump assemblies. Sourced directly through authorized supply channels, this fastener matches the original hardware used in production. Keep a few on hand — fasteners like this are commonly replaced during routine service and drum or component rebuilds.
Key Features
- OEM Nylon Insert Locking Integrity — The nylon collar is formed to the same torque-resistance specification as the original, preventing loosening under the sustained vibration loads common to mixer and pump operation.
- Exact Thread Form — 5/16-18 UNC X 1/2" — Correct unified coarse thread pitch and grip length install directly into existing tapped bosses with no rework to mating hardware.
- Broad Multiquip Fleet Coverage — Confirmed fit across MG30, MG30T2D, MG30M2D, MG30T3D, MG30M3D, EM12M, EM12ME51, EM12ME53, MC-42S, MC44SH, MC44SE, MC44S, CMS-44S, CMS-4S, EC-42S, WC-42S, EM-120PM, EM120SM, EM900SD, WM120PM, WM120SM, and MS-40M equipment.
- Vibration Resistance Where It Counts — Mixers and fireproofing pumps generate continuous cyclic loads that work standard fasteners loose over time; the nyloc design maintains preload through extended duty cycles.
- Ready for Scheduled Service — Fasteners at this size and grade are routinely inspected or replaced during drum, gearbox, and motor mount servicing — stocking this part keeps those jobs on schedule.
A nyloc fastener — sometimes called a nylon insert lock nut or nylon lock screw — uses a deformed nylon collar at the tip of the threaded shank to create prevailing torque resistance. When driven into a mating thread, the nylon deforms around the male thread form and creates friction that counteracts loosening caused by vibration and dynamic loading. On mixing and fireproofing pump equipment, where rotating drums, agitators, and pump heads generate persistent cyclic forces, standard fasteners can back out and cause component misalignment or failure. Using the correct OEM-specification nyloc, such as the Multiquip 961045, ensures the fastener maintains its clamp load throughout the service interval and that critical assemblies stay properly torqued.
