• Secure and flush installation with a standard 82° flat head profile, ensuring a smooth surface finish and enhanced aesthetics.
• Efficient driving and reduced cam-out with the Phillips No. 2 drive, allowing for quick assembly and consistent torque application.
• Full threading for maximum grip along the entire 3/8" length, providing superior holding power in plastic substrates.
• Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe and sustainable use in various industries.
• Precision compatibility with a No. 32 drill bit (0.116" diameter), facilitating easy and accurate pre-drilling for optimal performance.

Professional Applications & Engineering Value

These No. 6 x 3/8" TRS tapping screws are engineered specifically for plastic applications, where traditional fasteners may cause cracking or failure. The 18-8 stainless steel material offers exceptional corrosion resistance, making these screws suitable for outdoor, marine, or chemically exposed environments. The tri-lobe shank cross-section and thread-forming design displace plastic material during installation, creating strong, reliable threads without the need for tapping operations. This reduces assembly time and tooling costs while minimizing stress concentrations in brittle plastics. The Phillips flat head with an 82° countersink angle ensures a secure, flush fit, ideal for applications in electronics enclosures, automotive components, and consumer goods where aesthetics and safety are paramount. By integrating right-hand threading and a blunt tip, these screws provide consistent engagement and prevent damage to sensitive plastic structures.

Specification Summary & Compliance

This product features a thread diameter of 0.138" with approximately 19 threads per inch, ensuring precise fit and holding strength. Manufactured to standard dimensions, including a head diameter of 0.262" and length of 3/8", these screws are designed for use with a No. 32 drill bit (0.116" diameter) for optimal performance in plastic materials. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards is confirmed, guaranteeing adherence to environmental and safety regulations for industrial use.
