S-96817A783 Length 4 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ensuring long-term reliability in various environments.
• Enhanced torque transmission and reduced cam-out thanks to the Torx Plus IP3 drive, providing secure fastening and minimizing tool wear.
• Strong, reliable threads in plastic materials through the thread forming (TRS) design, which displaces material without creating chips for superior holding power.
• Consistent, flush installation with a rounded pan head profile, offering a neat finish and reducing the risk of snagging.
• Full-length threading for maximum grip across the entire 4mm length, ensuring even load distribution and vibration resistance.
• Simplified assembly process using a standard No. 56 drill bit (0.0465" diameter), enabling quick and precise hole preparation.
• Compliance with stringent environmental regulations including RoHS 3 and REACH, making it safe for use in regulated industries.

Professional Applications & Engineering Value

This M1.4 x 4mm Torx Plus TRS thread forming screw is expertly engineered for fastening in plastic applications, where traditional screws may strip or fail. The 18-8 stainless steel material provides excellent corrosion resistance, crucial for electronics, automotive components, and outdoor equipment. Its thread forming (TRS) design creates strong, load-bearing threads in ductile plastics by compressing the material, eliminating the need for tapped holes and reducing assembly steps. The Torx Plus IP3 drive ensures high torque transfer with minimal slippage, preventing damage to the screw head and plastic substrate. This combination of fully threaded construction and blunt tip allows for smooth, precise insertion, making it an ideal plastic fastener for high-volume production lines requiring reliability and efficiency.

Specification Summary & Compliance

This screw features a M1.4 metric size with an approximate thread pitch of 0.57mm, fully threaded shank, and a rounded pan head with a diameter of 2.35mm. It is designed as a thread forming (TRS) tapping screw for use with a No. 56 drill bit (0.0465" diameter). Manufactured to standard dimensional tolerances for metric tapping screws, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and suitable for global industrial use.
