Frequently Asked Questions
Q: What is the purpose of the EA E115 lock nut on manual pallet jacks?
A: The EA E115 lock nut is a self-locking fastener that prevents bolts and studs from loosening due to vibration and cyclic loading during pallet jack operation. The locking mechanism maintains assembly tension without requiring frequent retightening.
Q: What material and design features does the EA E115 lock nut have?
A: The EA E115 is typically made from hardened steel with either a nylon insert or deformed thread design that creates friction to resist rotation. Some versions use a serrated flange design that grips the fastener surface to prevent loosening.
Q: Which pallet jack models and manufacturers use the EA E115 lock nut?
A: The EA E115 is compatible with multiple manual pallet jack models from Crown, Toyota, Raymond, Yale, Hyster, Clark, and other standard manufacturers. Verify the thread pitch and size match the bolts or studs in your equipment assembly.
Q: When should the EA E115 lock nut be replaced?
A: Replace the EA E115 if the locking feature has been damaged or compromised through repeated use, if the nylon insert is worn away or deteriorated, if corrosion prevents proper function, or if the bolt continues to loosen after retightening.
Q: How many times can the EA E115 lock nut be reused?
A: Lock nuts with nylon inserts should not be reused multiple times as the insert loses its locking effectiveness with each removal and reinstallation. It is best practice to replace the EA E115 with a new lock nut each time the assembly is disassembled.
Q: What is the typical thread size range available for the EA E115 lock nut?
A: The EA E115 is available in multiple metric and imperial thread sizes to match common fastener applications in pallet jack assemblies. Confirm the exact thread pitch and diameter needed for your specific jack model before ordering.
