Professional Applications & Engineering Value
This Phillips pan head screw with internal-tooth lock washer delivers exceptional engineering value in applications where vibration-induced loosening compromises assembly integrity. The 18-8 stainless steel core material provides excellent corrosion resistance, while the passivated finish enhances surface durability in challenging environments. The integrated 410 stainless steel lock washer with internal teeth bites into both the screw head and mating surface, creating a permanent locking action that withstands continuous vibration and thermal cycling. With UNC coarse threads and Class 2A fit, these screws ensure reliable engagement in various materials, making them ideal for machinery, electrical enclosures, automotive components, and industrial equipment where maintenance access is limited and reliability is critical.
Specification Summary & Compliance
This fastener features 6-32 UNC coarse threads with Class 2A dimensional accuracy and fully threaded design for maximum engagement. Manufacturing complies with ASME B18.13 specifications, ensuring consistent quality and performance. The product meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) requirements for chemical safety, validated as of June 14, 2023. Both the screw body and internal-tooth lock washer utilize passivated finishes on their respective stainless steel materials for enhanced corrosion protection.
