Frequently Asked Questions
Q: What is the material composition of the N0891513810 lock washer?
A: The N0891513810 is fabricated from hardened spring steel with a plain finish suitable for indoor mechanical assembly. This material provides high tensile strength and maintains spring force under repeated mechanical vibration to prevent bolt loosening.
Q: What applications use the N0891513810 lock washer?
A: The N0891513810 is designed for manual pallet jack assemblies, specifically at pivot points and frame assembly locations. It functions as a locking fastener to prevent bolt preload loss and unwanted loosening under mechanical vibration and repetitive loading.
Q: What are the cross-reference part numbers for the N0891513810?
A: The N0891513810 is equivalent to part numbers N089151381A and N-08915-13810. All three designations refer to the same hardened spring steel lock washer designed for manual pallet truck assemblies.
Q: How long does the N0891513810 lock washer remain effective?
A: The N0891513810 is rated for continuous service in normal warehouse and assembly conditions. Hardened spring steel provides reliable bolt retention over extended operational life. Replace the washer if it becomes flattened, cracked, or loses visible spring characteristics, or if bolts at that location loosen repeatedly.
Q: What is the purpose of using the N0891513810 instead of a standard washer?
A: The N0891513810 lock washer prevents bolt preload loss caused by vibration, thermal cycling, and mechanical movement in manual pallet jack frames and pivot assemblies. Spring steel construction maintains constant clamping force that standard flat washers cannot provide, reducing maintenance downtime from loose fasteners.
