Professional Applications & Engineering Value
This 8-32 x 1-1/2" Black-Oxide 18-8 Stainless Steel Rounded Head Screw is engineered to solve critical fastening challenges in demanding industrial settings. The Black-Oxide finish on the 18-8 stainless steel substrate significantly enhances corrosion resistance, making it an ideal choice for applications exposed to moisture, chemicals, or outdoor elements, thereby extending service life and reducing maintenance. The combination of 70,000 psi tensile strength and a Rockwell B55 hardness ensures the screw can withstand substantial vibrational loads and tensile stress without failure. The fully threaded design with UNC coarse spacing and Class 3A fit provides superior engagement in a wide range of materials, from metals to plastics, preventing loosening and ensuring a secure, long-lasting connection in machinery, electrical enclosures, and assembly lines.
Specification Summary & Compliance
This screw features precise UNC 8-32 coarse threads with a Class 3A thread fit for high precision and strength. It is manufactured in compliance with the ASME B18.3 standard. The product is also confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to strict environmental and safety regulations for industrial components.
