• Easy installation and flush mounting with standard 82° countersink angle and Phillips No. 2 drive design
• Consistent thread engagement through fully threaded coarse UNC pattern with Class 2A fit for secure connections
• Industry-standard compliance meeting ASME B18.6.3 specifications for guaranteed quality and interchangeability
• Environmental responsibility with RoHS 3 and REACH compliance for safe industrial use
• Versatile 1 3/4" length providing ample threading for various material thicknesses in right-hand thread applications

Professional Applications & Engineering Value

These 316 stainless steel flat head screws deliver exceptional value in corrosive environments where standard fasteners fail. The passivated finish enhances the natural corrosion resistance of 316 stainless, making these Phillips drive screws ideal for marine, chemical processing, and food industry applications where moisture and chemicals are present. The fully threaded 10-24 UNC coarse thread pattern ensures maximum grip strength in softer materials while the 82° countersink angle provides a flush surface finish critical for safety and aesthetics. Engineered to ASME B18.6.3 standards, these screws maintain dimensional consistency across batches, reducing installation time and ensuring reliable performance in structural assemblies, equipment manufacturing, and maintenance operations where vibration resistance and long-term durability are paramount.
