LOCKWASHER
Frequently Asked Questions
Q: What is the 3291349 lockwasher used for on manual pallet jacks?
A: The 3291349 is a lockwasher fastener component designed to prevent bolt loosening due to vibration and repetitive use on manual pallet jack assemblies. It is commonly found in handle mechanisms, load wheel mounting points, and hydraulic lift cylinder connections.
Q: What is the difference between a standard washer and the 3291349 lockwasher?
A: A lockwasher has internal or external teeth or serrated edges that grip both the bolt head and the mounting surface. This prevents fastener rotation and loosening from vibration, whereas a flat washer only distributes load. The 3291349 provides superior vibration resistance on manual jacks.
Q: Which manual pallet jack models use the 3291349 lockwasher?
A: The 3291349 fits multiple manual pallet jack models from brands including Crown, Toyota, Raymond, and Hyster. Verify the exact bolt diameter and pitch matches your equipment specification before ordering. Contact us with your jack model number for compatibility confirmation.
Q: Can the 3291349 lockwasher be reused after fastener removal?
A: Lockwashers are typically single-use components. Once the teeth or serrations are compressed and deformed from initial fastening, they lose locking effectiveness. Replace with a new 3291349 during reassembly to maintain vibration resistance and fastener security.
Q: What material is the 3291349 lockwasher made from?
A: The 3291349 is typically manufactured from hardened steel for standard duty or stainless steel for wet storage and outdoor applications. Steel versions suit warehouse use, while stainless variants resist corrosion in damp or chemical environments.
Q: Does the 3291349 require special handling or storage?
A: Store the 3291349 lockwashers in a dry environment to prevent rust. Steel versions may develop surface corrosion if stored in high-humidity areas. Ensure packaging protects against moisture. Inspect before use for damage or corrosion that may reduce locking effectiveness.
