The Multiquip 7971 Slotted Nut 5/8 NP TRLR-10 is a genuine OEM fastener designed for the TRLR-10 water trailer. As a direct OEM component sourced through Multiquip's authorized parts network, the part meets the exact specifications called for in the original assembly. This is the correct slotted nut to use when servicing or reassembling TRLR-10 water trailer hardware, ensuring the fastener engages and retains properly without guesswork. When you need the right part the first time, sourcing genuine OEM hardware like the 7971 eliminates the risk of using an incorrect specification fastener.
Key Features
- OEM-Spec Fastener Grade — Manufactured to the exact thread pitch, hex size, and slot configuration specified for the TRLR-10, ensuring proper torque engagement and cotter pin retention.
- Direct-Fit Hardware — Installs into the same position as the original without rework, threading directly onto the corresponding stud or shaft as designed in the factory assembly.
- Confirmed TRLR-10 Compatibility — Verified genuine OEM fitment for the Multiquip TRLR-10 water trailer series.
- Cotter Pin Retention Design — The slotted profile aligns with a cotter pin or castellated retainer to lock the nut in position under load, preventing loosening during trailer operation.
- Correct Corrosion-Resistant Finish — NP (nickel-plated) finish helps resist surface corrosion in outdoor and wet-environment trailer service conditions.
A slotted nut — sometimes called a castellated nut — is a fastener with evenly spaced slots cut across the top face that allow a cotter pin or safety wire to pass through a corresponding hole in the bolt or shaft, mechanically locking the nut in place. This design is used in trailer applications where vibration or cyclic loading would otherwise cause a standard nut to back off over time. When a slotted nut is missing, damaged, or replaced with the wrong size or thread pitch, the assembly it secures can loosen progressively during use, leading to component movement, accelerated wear, or loss of retention in safety-critical connections such as wheel hubs or axle ends.
