Frequently Asked Questions
Q: What material is the CR 60021-096 made from and what are its grade specifications?
A: CR 60021-096 is manufactured from heat-treated carbon steel and meets or exceeds Grade 8 specifications. Grade 8 fasteners provide high tensile strength and greater load-bearing capacity, making them suitable for critical applications. The nut achieves a minimum Rockwell C33 hardness, delivering superior strength and durability for wheel and axle retention on Crown PE 3000 series pallet trucks.
Q: What are the thread specifications for the CR 60021-096?
A: CR 60021-096 is a 1-12 Unified National Coarse (UNC) hex nut. The 1-12 UNC thread is standard for heavy-duty fastening applications and provides secure engagement for wheel and axle assemblies where tight fastening is critical to equipment safety and reliability.
Q: Which Crown pallet truck models use the CR 60021-096?
A: CR 60021-096 is specified for Crown PE 3000 series pallet trucks. Other Crown models may use different nut sizes or grades. Always verify the part number in your equipment manual before ordering to ensure correct fitment and fastening strength.
Q: Why is Grade 8 fastener material important for this application?
A: Grade 8 fasteners provide higher tensile strength and greater load-bearing capacity than lower grades. On Crown PE 3000 pallet trucks, Grade 8 nuts ensure wheel and axle assemblies remain secure under heavy loads and repeated use. This grade specification is critical for operator safety, load stability, and equipment reliability.
Q: How do I verify that CR 60021-096 is the correct replacement for my Crown pallet truck?
A: Verify your equipment is a Crown PE 3000 series pallet truck by checking the model plate on the frame. Consult your equipment manual to confirm the fastener location calls for a 1-12 UNC hex nut. If fasteners are loose, stripped, or cannot be tightened securely, replacement with CR 60021-096 is appropriate. Measure the thread diameter and pitch to confirm correct fit.
