Multiquip EM1017 Pressure Nut 1/2 NC

The Multiquip EM1017 Pressure Nut 1/2 NC is a genuine OEM fastener used across a wide range of Multiquip, Whiteman, and Essick equipment platforms. This EM1017 pressure nut is sourced directly from Multiquip and meets the same dimensional and material standards as the hardware originally installed at the factory. It is confirmed to fit an extensive lineup including ride-on power trowels, concrete mixers, mortar mixers, vibratory screeds, water trailers, roller screeds, light towers, flat saws, and rollers. Whether you are servicing a JWN24, HTN27K, HTN28K, STX55, HTX44, MD80, MD105, LD6, PRX series trowel, MC44S, MC64, MC94, WM63, WM70, WM90, WM120, EM70, EM90, or EM120 mixer, or a WSHE-A series screed, the EM1017 delivers a direct, thread-matched replacement every time.

Key Features

• Genuine OEM Threaded Hardware: — Manufactured to Multiquip's original material and thread-form specifications for a 1/2 NC pressure nut, ensuring correct clamping load and thread engagement on every application.
• Direct Thread Match: — The 1/2 NC (National Coarse) thread profile installs directly into existing threaded bores and onto existing fastener patterns across all listed equipment — no recutting or chasing required.
• Exceptionally Wide Fitment: — A single EM1017 covers ride-on trowels (JWN24, HTN, HTX, STX, LD, MD, HHN, PRX series), concrete and mortar mixers (MC, WM, EM series), vibratory screeds (WSHE-A), roller screeds (WRS), water trailers, light towers, and more.
• Consistent Clamping Integrity: — A properly torqued pressure nut maintains the designed preload on the mating assembly, preventing loosening from vibration and preserving alignment of the components it secures across high-cycle machine environments.
• Backed by Multiquip OEM Sourcing: — Sold by DHS Equipment as an authorized Multiquip replacement, so the part number, thread specification, and material grade are verified against current Multiquip parts documentation.

A pressure nut is a hardened threaded fastener designed to maintain a specific clamping force against a mating surface, shaft shoulder, or bearing assembly under sustained mechanical load and vibration. On equipment like concrete trowels, mixers, and screeds — which generate constant cyclical forces during operation — maintaining correct fastener preload is critical to keeping rotating assemblies, gearbox components, and structural joints within their designed tolerances. When a pressure nut becomes stripped, corroded, or loses its seating, the resulting looseness can cause accelerated wear on adjacent components, misalignment of shafts or blades, and eventual mechanical failure of the assembly it secures.
