S-97349A420 Length 1/4" 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 thread forming design creates strong, permanent threads in plastic materials without chips, reducing assembly time and cleanup.
• Optimized for plastic applications with blunt tip and DST thread form to prevent material cracking and ensure secure, vibration-resistant fastening.
• Quick installation using standard No. 2 Phillips drive, allowing for high-torque application with common tools and reduced cam-out risk.
• Full threading along the 1/4" length provides maximum grip and holding power across the entire engagement area in plastic substrates.
• Precise No. 32 drill bit compatibility ensures proper hole sizing for optimal thread engagement and assembly consistency.
• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and suitability for global industrial and consumer product markets.

Professional Applications & Engineering Value

These No. 6 x 1/4" 18-8 stainless steel tapping screws are engineered specifically for plastic assembly applications, where material integrity and fastener durability are critical. The thread forming (DST) design displaces plastic material without cutting, eliminating chips that could interfere with electronics or moving parts. This makes them ideal for electronics enclosures, automotive trim, and consumer appliances where vibration resistance and aesthetic finish matter. The Phillips pan head provides a low-profile, finished appearance while the fully threaded shank ensures uniform stress distribution, preventing plastic fatigue and thread stripping. Manufactured from corrosion-resistant 18-8 stainless steel, these screws maintain performance in outdoor or chemically exposed environments where plastic components are commonly used.

Specification Summary & Compliance

This tapping screw features a No. 6 size with 0.138" thread diameter and 19 threads per inch in a right-hand direction. The 1/4" length is fully threaded with a blunt tip and round shank cross-section. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restricted substance compliance for industrial and consumer products. Designed for use with a No. 32 drill bit (0.116" diameter) in plastic materials, it delivers precise thread engagement and reliable performance in demanding assembly applications.
