Frequently Asked Questions
Q: What are the specifications of the CR 060017-021 cap screw?
A: The CR 060017-021 is a 3/8 inch -16 UNC thread cap screw made from Grade 8 alloy steel with a plain finish. This high-strength fastener is designed for demanding applications in electric lift truck assemblies.
Q: Which Crown electric pallet jack models use the CR 060017-021?
A: The CR 060017-021 fits Crown PE 4000 and PE 4500 Series electric pallet trucks. Alternate model designation PE4000 also uses this fastener. Always verify your specific serial range for correct fitment.
Q: Why is Grade 8 alloy steel used for this screw?
A: Grade 8 alloy steel provides high tensile strength and improved fatigue resistance compared to lower grades. This material is critical for lift mechanism fasteners that experience repeated load cycles and high stress in electric pallet truck operation.
Q: Does the CR 060017-021 require a specific torque specification?
A: Yes, Grade 8 fasteners require precise torque application. Consult your Crown PE 4000 or PE 4500 service manual for the exact torque specification for 3/8 inch -16 UNC fasteners. Under or over torquing can cause fastener failure or equipment damage.
Q: Can the plain finish of the CR 060017-021 be used in wet or cold storage environments?
A: The plain finish offers no corrosion protection. In wet or cold storage applications, this fastener may develop surface rust over time. Grade 8 alloy steel resists corrosion better than standard carbon steel, but monitor condition regularly in high-moisture environments.
