Frequently Asked Questions
Q: What is the UL 1408 bolt used for in manual pallet jacks?
A: The UL 1408 is a fastener bolt that secures structural frame components in manual pallet jacks. It may be used to attach scissor arms to the main frame, secure the pump assembly, or join reinforcing plates. This bolt is compatible with standard manual pallet jacks from Crown, Toyota, Raymond, Yale, and other manufacturers using similar frame designs.
Q: What are the material and size specifications of the UL 1408 bolt?
A: The UL 1408 is a grade 8 or higher steel bolt with specifications typically ranging from 3/8 inch to 1/2 inch diameter, with lengths between 1 and 2 inches depending on the assembly location. The bolt is rated for the shear and tensile forces generated during normal pallet jack operation with loads up to 5500 pounds.
Q: How often should the UL 1408 bolt be inspected or replaced?
A: Inspect UL 1408 bolts every 6 to 12 months for signs of loosening, corrosion, or shearing. Under normal operating conditions, bolts remain serviceable for several years. Replace bolts if they show visible damage, thread stripping, or if they cannot be tightened securely due to wear.
Q: What indicates the UL 1408 bolt needs replacement?
A: Replace the UL 1408 bolt if it is stripped, corroded, or if the bolt head or threads are damaged. A bolt that cannot hold tension or repeatedly loosens during operation must be replaced. Failure to replace compromised bolts can cause frame misalignment and unsafe equipment operation.
Q: Can the UL 1408 bolt be cross-referenced to industrial fastener standards?
A: The UL 1408 bolt conforms to standard SAE or ISO fastener specifications. Before ordering a replacement, verify the exact bolt diameter, length, thread pitch, and grade required for your equipment. Using a bolt with incorrect specifications can result in joint failure or safety issues.
