Frequently Asked Questions
Q: What is the EA A112 lock nut used for on Eagleman pallet jacks?
A: The EA A112 is a lock nut that secures the A-frame assembly on Eagleman manual pallet jacks. The nylon insert prevents vibration-induced loosening during lifting and lowering operations, maintaining frame structural integrity.
Q: What are the specifications of the EA A112 lock nut?
A: The EA A112 features a 1/2-13 UNC thread, 0.750 inch across flats, constructed from SAE 1045 carbon steel with a heat-treated hardness of Rockwell C38 minimum. It has an industrial phosphate oil finish for corrosion resistance.
Q: Which Eagleman pallet jack models use the EA A112?
A: The EA A112 lock nut fits Eagleman model A series manual pallet jacks. Verify your jack model and frame assembly type match this part number before ordering.
Q: What cross-reference part numbers exist for the EA A112?
A: The EA A112 supersedes part number EGA112 and is equivalent to EAA112. If you are replacing older lock nuts, the EA A112 is the current production specification.
Q: How often should the EA A112 lock nut be inspected or replaced?
A: Inspect EA A112 lock nuts during routine maintenance to confirm they remain tight. Replace the lock nut if it is loose, cracked, or if the nylon insert is damaged or degraded, as this compromises vibration-damping performance.
Q: Why does the EA A112 use SAE 1045 carbon steel?
A: SAE 1045 carbon steel, when heat-treated to Rockwell C38 minimum, provides the strength and fatigue resistance required to withstand repeated clamping cycles and dynamic loads in pallet jack frame assemblies. The phosphate finish resists corrosion in warehouse environments.
