S-97349A424 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in humid or chemical environments.
• Efficient thread forming design creates strong, permanent threads in plastic materials without pre-tapping, reducing assembly time and tooling costs.
• Optimized Phillips drive provides secure tool engagement and reduces cam-out risks during high-torque installation in plastic substrates.
• Full threading along the 1" length delivers maximum grip and vibration resistance across the entire engagement area in plastic assemblies.
• Precision dimensional compliance with DST thread standards ensures consistent performance and interchangeability in high-volume manufacturing.
• Environmental regulation compliance with RoHS 3 and REACH standards makes these screws suitable for global supply chains and sensitive applications.
• Blunt tip design prevents material splitting in brittle plastics while maintaining easy alignment during installation.

Professional Applications & Engineering Value

These No. 6 x 1" stainless steel tapping screws are specifically engineered for plastic assembly challenges where traditional fasteners fail. The thread forming DST design eliminates the need for separate tapping operations by displacing plastic material to create strong, load-bearing threads that won't strip under vibration. The 18-8 stainless steel composition provides essential corrosion resistance for outdoor equipment, marine components, and chemical processing applications where moisture exposure would degrade standard fasteners. With fully threaded shanks and Phillips pan head configuration, these screws distribute clamping force evenly across plastic surfaces, preventing stress cracking while maintaining flush mounting profiles. Ideal for plastic fabrication, electronic enclosures, automotive trim, and consumer products requiring reliable, permanent fastening solutions.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.138" thread diameter and 19 TPI thread pitch for consistent performance in plastic applications. The DST thread forming design complies with industry standards for plastic fastening, while the No. 32 drill bit size (0.116" diameter) ensures proper hole preparation. These screws feature Class 2A thread tolerances for reliable engagement and are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for use in restricted substance-sensitive applications.
