S-97349A412 Length 5/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in humid or demanding environments.
• Efficient installation in plastics through thread forming (DST) design that creates strong, permanent threads without pre-tapping.
• Optimized drive engagement with Phillips No. 1 drive, reducing cam-out and improving torque transfer during assembly.
• Enhanced material integrity using blunt tip and fully threaded design to prevent plastic cracking and ensure maximum holding power.
• Precision fit guidance with recommended No. 48 drill bit (0.076" diameter), enabling clean holes and secure fastening in plastic substrates.
• Broad regulatory compliance meeting RoHS 3 and REACH standards, making them suitable for sensitive and export-focused applications.
• Versatile pan head profile offering a standard, low-profile finish that sits flush and distributes clamping force evenly.

Professional Applications & Engineering Value

These No. 2 x 5/16" stainless steel tapping screws are precision-engineered for plastic assembly challenges, where material stripping or stress cracking are common failures. The 18-8 stainless steel provides excellent resistance to oxidation and chemicals, crucial for outdoor enclosures, electrical housings, or automotive trim. The thread forming (DST) design displaces plastic material to create robust internal threads, eliminating the need for inserts and reducing assembly steps. Combined with a Phillips pan head and fully threaded shank, these screws ensure consistent clamp load and vibration resistance, making them ideal for high-volume production lines in consumer electronics, appliance manufacturing, and industrial equipment where RoHS/REACH compliance is mandatory.
