Frequently Asked Questions
Q: What is the thread size and pitch specification for the 302400 locking nut?
A: The 302400 is a nylon-insert self-locking nut sized for forklift structural and drivetrain assemblies. Verify the thread diameter, pitch (metric or UNC), and height match your equipment fastener specifications.
Q: What is the material grade of the 302400 locking nut?
A: The 302400 is typically grade 8.8 or higher hardened steel with a nylon-insert locking feature. This grade provides high tensile strength suitable for engine block, transmission, and mast assembly applications.
Q: How many times can the 302400 locking nut be reused?
A: Nylon-insert locking nuts can be reused 3 to 5 times before the nylon insert degrades and locking friction diminishes. Once the insert becomes loose or flattened, replace the nut to maintain clamping force.
Q: What applications on a forklift use the 302400 locking nut?
A: The 302400 is used in engine fastening, transmission mounting, steering box assembly, mast pivot fastening, and load wheel axle retention. High-vibration areas benefit from the nylon-insert locking feature.
Q: Can the 302400 locking nut be used with a washer?
A: Yes, use a hardened washer between the nut and assembly surface, especially on softer materials. This prevents the nut from pulling through and distributes clamping pressure evenly.
