Frequently Asked Questions
Q: What are the technical specifications of CR 060011-027?
A: CR 060011-027 is a #4-40 UNC machine screw with 0.112 inch diameter and flat slotted head design. It is manufactured from carbon steel per ASTM A1008/A1008M standard with phosphate and oil finish. Minimum tensile strength is 60,000 psi, meeting Crown structural fastening requirements.
Q: Which Crown models use CR 060011-027?
A: CR 060011-027 is specified for Crown GPW Series, PE 4500 Series, and M Series electric lift trucks. This part is used in applications requiring the higher tensile strength of carbon steel per ASTM A1008 standards.
Q: Why does CR 060011-027 have 60,000 psi tensile strength?
A: The 60,000 psi minimum tensile strength of CR 060011-027 ensures the fastener can withstand the mechanical stresses and load transfer in Crown lift truck applications. This specification is critical for safety-critical connections where fastener failure could compromise equipment performance.
Q: What is the purpose of phosphate and oil finish on CR 060011-027?
A: The phosphate and oil finish protects the carbon steel from corrosion and extends fastener life in warehouse and material handling environments. This coating combination is standard for industrial fasteners and prevents rust formation that could weaken the screw over time.
Q: What does ASTM A1008 specification mean for CR 060011-027?
A: ASTM A1008/A1008M is the material specification standard for cold-rolled carbon steel fasteners. This specification ensures CR 060011-027 meets precise mechanical property requirements including tensile strength, hardness, and ductility needed for reliable performance in Crown lift trucks.
Q: Can CR 060011-027 be used interchangeably with CR 060011-022?
A: CR 060011-027 and CR 060011-022 are different fasteners. CR 060011-027 has higher tensile strength (60,000 psi) and ASTM A1008 carbon steel material, while CR 060011-022 uses standard steel. Use the exact part specified for your Crown model and application location.
