S-96817A328 Length 12 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with T20 Torx drive, reducing cam-out and tool wear for reliable, high-torque fastening in plastic assemblies.
• Enhanced corrosion resistance from zinc-plated steel construction, ensuring long-term durability in various industrial environments.
• Secure and stable fastening with a wide pan flange design that distributes load evenly, preventing pull-through in plastic materials.
• Efficient thread forming using TRS thread forming method, creating strong, permanent threads in plastics without pre-tapping.
• Full threading for maximum grip along the 12mm length, providing consistent holding power in plastic applications.
• Optimized for plastic use with blunt tip and specific drill bit size (45 / 0.082"), minimizing material stress and cracking during installation.
• Compliance with environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use in global markets.

Professional Applications & Engineering Value

These M4 x 12mm zinc-plated steel tapping screws are engineered to address common challenges in plastic fastening, such as material cracking and thread stripping. The TRS thread forming design displaces plastic material to form precise, robust threads, eliminating the need for inserts and reducing assembly steps. With a T20 Torx drive, they deliver high torque transmission without slippage, ideal for automated or high-volume production lines. The flanged pan head provides a wide bearing surface, distributing clamp force to prevent damage in soft plastics like ABS or polycarbonate. This combination of metric screw precision and zinc-plated protection ensures reliable performance in electronics enclosures, automotive trim, and consumer goods, where vibration resistance and longevity are critical.

Specification Summary & Compliance

This screw features an M4 metric size with a length of 12mm, fully threaded right-hand design, and an approximate thread pitch of 1.79mm. It includes a flange diameter of 8mm and is compatible with drill bit size 45 (0.082"). Manufactured to standard thread forming specifications for plastic applications, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for industrial use.
