Frequently Asked Questions
Q: What are the dimensions and specifications of the 51854030 lockwasher?
A: The 51854030 is a helical spring lockwasher with inner diameter 0.50 inches, outer diameter 0.875 inches, and thickness 0.110 inches. It is manufactured from SAE 1050 carbon steel, through hardened, with plain finish per ANSI B18.21.1 specifications.
Q: Which manual pallet jack models use the 51854030 lockwasher?
A: The 51854030 is compatible with manual pallet jack assemblies from Crown, Yale, Raymond, Toyota, and other major manufacturers. The 0.50-inch bore size is common for wheel axle and handle pivot fastening. Verify bore diameter matches your equipment before ordering.
Q: Why use a spring lockwasher instead of a standard washer?
A: The helical spring design of the 51854030 provides vibration resistance and prevents fastener loosening under the constant movement and stress of material handling operations. Carbon steel through-hardened construction maintains spring tension over time.
Q: How long does the 51854030 lockwasher typically last?
A: The SAE 1050 through-hardened carbon steel construction provides extended service life in normal manual pallet jack applications. Lockwashers should be replaced if deformed, cracked, or if fasteners repeatedly loosen after tightening.
