Professional Applications & Engineering Value
This 10-24 UNC threaded rounded head screw delivers critical performance advantages in industrial settings where corrosion resistance and mechanical reliability are paramount. Manufactured from 18-8 stainless steel with a passivated finish, it effectively withstands exposure to moisture, chemicals, and outdoor elements, reducing maintenance needs and extending service life. The coarse UNC threading with Class 3A fit ensures rapid assembly and secure fastening in materials prone to stripping, while the hex drive prevents cam-out during high-torque installation. Ideal for machinery, electrical enclosures, and structural assemblies, this fully threaded fastener provides consistent 70,000 psi tensile strength to handle dynamic loads and vibration without failure.
Specification Summary & Compliance
This fastener maintains precise Class 3A thread fit per UNC standards with a diameter of 0.19" and coarse thread spacing. Manufacturing adheres to ASME B18.3 specifications (ASTM F879), ensuring dimensional accuracy and interchangeability. The screw is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances for safe use in regulated industries.
