- Compliance with major industry standards including ASME B18.6.3, RoHS 3, and REACH ensures product quality, safety, and environmental responsibility.
Professional Applications & Engineering Value
Engineered for industrial durability, these 8-32 UNC hex head screws in 18-8 Stainless Steel address critical challenges in machinery, electronics, and structural assemblies. The coarse thread design resists vibration loosening and simplifies installation in soft metals or plastics, while the flange eliminates the need for separate washers, reducing part count and assembly time. With a Rockwell B100 hardness and 100,000 psi tensile strength, they maintain clamp force under dynamic loads, preventing joint failure. The external hex drive ensures secure tool engagement for high-torque applications, making them a reliable choice for industrial fastening where corrosion resistance and regulatory compliance are paramount.
Specification Summary & Compliance
This screw features a Class 2A thread fit per UNC standards, ensuring precise dimensional accuracy and interchangeability. It is manufactured in compliance with ASME B18.6.3 for consistent quality and performance. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and suitable for global industrial use.
