Professional Applications & Engineering Value
These 316 stainless steel rounded head screws deliver critical corrosion protection in demanding industrial settings where exposure to chemicals, moisture, or salt spray would compromise ordinary fasteners. The passivated finish enhances the natural corrosion resistance of 316 stainless steel, making these Phillips head screws ideal for marine equipment, chemical processing plants, food processing machinery, and outdoor applications. The UNC coarse thread configuration with Class 2A fit ensures reliable engagement in various materials while the pan head design provides a low-profile fastening solution with excellent bearing surface. Engineered to maintain integrity in temperature variations and corrosive environments, these fully threaded screws offer consistent performance where fastener failure is not an option.
Specification Summary & Compliance
This 2-56 UNC 3/4" screw features precision Class 2A thread fit per ASME B18.6.3 standards, ensuring dimensional accuracy and interchangeability. The manufacturing process adheres to strict quality controls with fully threaded right-hand coarse threads measuring 0.086" in diameter. Regulatory compliance includes RoHS 3 (2015/863/EU) restriction of hazardous substances and REACH (EC 1907/2006) compliance for chemical safety, making these screws suitable for global industrial applications requiring certified components.
