Professional Applications & Engineering Value
These passivated 18-8 stainless steel rounded head screws address critical needs in industrial settings where corrosion resistance and mechanical strength are paramount. The 3/8"-16 UNC coarse thread ensures quick, secure fastening in metals and composites, reducing assembly time while the pan head profile distributes pressure evenly to minimize surface damage. With a partial threading design, they prevent material distortion in applications like machinery assembly, electrical enclosures, and structural frameworks. The passivation surface treatment enhances durability against chemicals and moisture, making them ideal for outdoor equipment, marine hardware, and manufacturing systems requiring long-term reliability under stress.
Specification Summary & Compliance
This screw features precise Class 2A thread fit per UNC standards, ensuring interchangeability and smooth engagement. Dimensions include a 2 1/2" length with a minimum thread length of 1 1/2", and it conforms to ASME B18.6.3 manufacturing specifications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its suitability for environmentally conscious industrial and engineering projects.
