Frequently Asked Questions

Q: What is SKU 1366629 and why is it used in manual pallet jacks?
A: SKU 1366629 is a steel lockwasher designed to secure fastened parts against vibration and rotational load. In manual pallet jack assemblies, lockwashers prevent bolts and screws from loosening during equipment operation and movement.

Q: What types of manual pallet jack assemblies use this lockwasher?
A: This lockwasher is a general purpose industrial fastener suitable for multiple manual pallet jack applications across standard OEM brands. It is used on hydraulic cylinders, pump assemblies, lift mechanisms, and structural connections subject to vibration and movement.

Q: What is the material composition and why is steel used for this lockwasher?
A: This lockwasher is manufactured from steel, which provides superior strength and vibration-locking performance under industrial duty conditions. Steel resists deformation under the repetitive loads typical of manual pallet jack operation.

Q: How long does this lockwasher remain effective?
A: Lockwashers remain effective indefinitely if not damaged or deformed. They do not wear out like mechanical parts. Replace lockwashers when fasteners are removed, or if washers show permanent deformation, rust damage, or loss of spring tension.

Q: What should I do if a fastener keeps loosening on my manual pallet jack?
A: Check that the existing lockwasher is not damaged or deformed. If the washer is intact and the fastener still loosens, the fastener may require re-tightening or the assembly may have excessive movement. Replace worn lockwashers with new ones to restore vibration-locking performance.

Q: Are there different sizes of this lockwasher and how do I identify the correct size?
A: Lockwashers come in multiple sizes to match different bolt and screw diameters. Measure the fastener diameter or remove the existing lockwasher to determine the correct inner diameter. Always use a lockwasher size that matches your fastener specifications.
