S-92400A340 Length 7/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Exceptional holding power in plastic materials thanks to the thread-forming tri-lobe shank design that creates secure, permanent threads
• Efficient high-torque installation enabled by the external hex drive head for reliable fastening without stripping
• Reduced risk of material splitting with blunt tip design that displaces plastic without cutting or creating stress points
• Full-length threading ensures maximum engagement and consistent clamping force along the entire fastener length
• Precise dimensional accuracy with No. 12 thread diameter and 11 threads per inch for reliable performance in standard drill sizes
• Compliance with international safety standards including RoHS 3 and REACH for environmentally responsible manufacturing

Professional Applications & Engineering Value

These No. 12 TRS tapping screws deliver exceptional engineering value for plastic assembly applications where vibration resistance and long-term reliability are critical. The thread-forming tri-lobe design creates stronger, more durable threads in plastic materials compared to conventional fasteners, eliminating the need for separate tapping operations and reducing assembly time. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the external hex drive ensures maximum torque transmission during installation. These self-tapping screws are specifically engineered for plastic components in automotive trim, electrical enclosures, consumer products, and industrial equipment where secure fastening without material damage is paramount.

Specification Summary & Compliance

This TRS tapping screw features a No. 12 thread diameter (0.216") with 11 threads per inch and 7/16" length, manufactured to precise dimensional standards for consistent performance.
