  • Precise component alignment with Class 3A thread fit and controlled shoulder tolerances for secure assembly
  • Superior mechanical strength with 70,000 psi tensile strength and Rockwell B60 hardness for heavy-duty applications
  • Enhanced grip and torque transmission through knurled head and 1/8" hex socket drive design
  • Industry-standard compatibility with 10-24 UNC coarse threads meeting ASME B18.3 specifications
  • Regulatory compliance assurance with RoHS 3 and REACH environmental standards for global supply chain integration
  • Optimized load distribution with 3/8" shoulder length providing stable bearing surfaces for rotating components

Professional Applications & Engineering Value

This nickel alloy shoulder screw delivers critical engineering solutions where precision alignment and corrosion resistance are paramount. The 10-24 UNC coarse thread with Class 3A fit ensures vibration-resistant fastening in machinery, while the knurled socket head provides superior torque application in confined spaces. The 3/8" shoulder length with tight diameter tolerance maintains exact component positioning in assemblies, preventing misalignment in rotating mechanisms. Ideal for precision instruments, automotive systems, and industrial equipment, this shoulder screw withstands extreme conditions thanks to its nickel alloy composition and 70,000 psi tensile strength, reducing maintenance frequency and downtime in demanding applications.

Specification Summary & Compliance

Manufactured to ASME B18.3 standards with Class 3A thread fit precision. Shoulder diameter tolerance maintained at -0.004" to -0.002" with shoulder length tolerance of -0.005" to 0.005". Fully compliant with RoHS 3 (2015/863/EU) with exemption 6(c) and REACH (EC 1907/2006) regulations. Mechanical properties include 70,000 psi tensile strength, 35,000 psi minimum shear strength, and Rockwell B60 hardness for consistent performance.
