S-97349A421 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 various environments.
• Efficient thread forming design creates strong, permanent threads in plastic materials without pre-tapping, reducing assembly steps.
• Optimized Phillips drive system with No. 2 size provides secure tool engagement and prevents cam-out during installation.
• Pan head profile offers a low-profile finish with excellent bearing surface for secure fastening in plastic assemblies.
• Precision dimensional compatibility with No. 32 drill bits (0.116" diameter) ensures proper fit and reduces material stress.
• Full threading along 5/16" length maximizes grip strength and distributes load evenly across plastic components.
• Environmental compliance assurance with RoHS 3 and REACH regulations meets international manufacturing standards.

Professional Applications & Engineering Value

These No. 6 x 5/16" stainless steel tapping screws are specifically engineered for plastic assembly applications where material integrity and corrosion resistance are critical. The 18-8 stainless steel composition provides excellent durability against environmental factors, while the thread forming (DST) technology displaces plastic material to create strong, strip-resistant threads without generating chips. This eliminates the need for separate tapping operations and reduces assembly time in high-volume production. The Phillips pan head design ensures flush mounting with sufficient drive torque transmission, making these tapping screws for plastic ideal for electronics enclosures, automotive trim components, and consumer products where vibration resistance and aesthetic finish are important considerations.

Specification Summary & Compliance

These screws feature a 0.138" thread diameter with 19 threads per inch and fully threaded 5/16" length for maximum engagement. The rounded pan head measures 0.254" in diameter with 0.097" height, compatible with standard No. 32 drill bits (0.116" diameter). Manufactured to precise dimensional standards with right-hand threading and blunt tip for controlled penetration. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions adherence.
