Professional Applications & Engineering Value
Engineered for industrial applications requiring precision and reliability, these Black-Oxide Alloy Steel rounded head screws solve critical fastening challenges. The UNC coarse thread configuration with Class 3A fit provides superior vibration resistance in machinery, automotive assemblies, and heavy equipment where loosening under dynamic loads is a concern. The flanged design eliminates the need for separate washers, streamlining assembly while providing enhanced bearing surface. With 120,000 psi tensile strength and Rockwell C39 hardness, these screws maintain structural integrity in high-stress environments, making them ideal for construction equipment, industrial machinery frames, and automotive subsystems where failure is not an option.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with precise Class 3A thread tolerance for consistent fit and performance. The 10-24 UNC coarse thread with right-hand direction and 0.19" thread diameter ensures compatibility with standard industrial components. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting the latest industry standards for safe and sustainable manufacturing practices.
