Professional Applications & Engineering Value
These 316 stainless steel flat head screws are engineered to address critical challenges in industrial settings where corrosion, high stress, and regulatory compliance are paramount. The passivated finish significantly enhances the innate corrosion resistance of 316 stainless steel, making these Phillips drive screws ideal for marine, chemical processing, and food-grade equipment. The UNC coarse thread and Class 2A fit facilitate quicker assembly and provide reliable holding power in softer materials or applications prone to vibration loosening. With a fully threaded 2-inch design and a standard 82° countersink angle, they ensure a flush fit and even load distribution, preventing surface damage and maintaining structural integrity in demanding industrial applications.
Specification Summary & Compliance
This product adheres to Class 2A thread fit tolerances as per the UNC coarse thread standard, ensuring dimensional accuracy and interchangeability. Manufacturing and quality are governed by the ASME B18.6.3 specification. The screw is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for use in regulated markets.
