Multiquip APRD27834 Kep Nut #10-32

The Multiquip APRD27834 Kep Nut #10-32 is a genuine OEM fastener designed for AP6 and AP8 series water pumps. As a factory-sourced component, it is manufactured to the exact thread specification and dimensional tolerances required for correct installation on these machines. Verified fitment covers both the AP6 and AP8 pump models, so you can order with confidence. Sourcing the correct fastener matters — an improperly matched nut can back off under vibration or strip threads on sensitive pump hardware, making the right part critical to a solid, lasting repair.

Key Features

• OEM Thread Accuracy: — Factory-spec #10-32 thread form ensures full engagement and correct torque retention on AP6 and AP8 pump assemblies.
• Integrated Locking Washer: — The kep-style captive washer bites into the mating surface under load, resisting loosening from pump vibration without requiring a separate lock washer.
• Confirmed Fitment: — Sourced directly from Multiquip for AP6 and AP8 water pump applications; matches the original hardware specification exactly.
• Corrosion-Resistant Construction: — Built to withstand the wet, high-humidity operating environment typical of water pump service and prevent fastener seizure over time.
• Direct Drop-In Replacement: — Installs in place of the original fastener with no rework, retapping, or hardware substitution needed.

A kep nut is a standard hex nut with a free-spinning captive tooth lock washer factory-assembled onto its bearing face. When tightened, the serrated washer bites into the clamped surface and creates resistance to rotational loosening — making it particularly well-suited for equipment subject to continuous vibration, such as water pumps. A missing, stripped, or incorrect fastener in this application can allow panels, guards, or internal components to work loose, leading to leaks, misalignment, or secondary damage. Using the correct OEM-specified kep nut ensures the joint stays secure throughout the service life of the pump.
