Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for demanding industrial environments
- Enhanced torque transmission and reduced cam-out with the precision T8 Torx drive system
- Exceptional holding power in plastic materials due to the Tri-Lobe shank cross-section that displaces material to form strong, reliable threads
- Streamlined, low-profile installation with a standard 82° flat head that sits flush for a clean finish
- Simplified and secure installation process as a thread-forming (TRS) screw, eliminating the need for a separate tapping operation
- Full-length gripping strength provided by the fully threaded design for consistent performance along the entire fastener length
- Guaranteed material and process integrity with full compliance to RoHS 3 and REACH environmental regulations
Professional Applications & Engineering Value
This No. 4-20 plastic tapping screw is engineered to solve critical challenges in plastic assembly. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, ensuring long-term reliability in varied conditions. The TRS (Thread Rolling Screw) design with its Tri-Lobe shank is specifically formulated for thread forming in plastics, creating strong, strip-resistant threads without generating chips. This eliminates the risk of contamination in sensitive assemblies. The combination of the T8 Torx drive and flat head allows for high-torque installation with a clean, flush finish, making it an ideal industrial fastener for electronics enclosures, automotive trim, and consumer products where vibration resistance and a professional appearance are paramount.
Specification Summary & Compliance
This screw conforms to standard inch system dimensions: No. 4-20 thread with a 5/8" length and is fully threaded. It is designed for use with a No. 44 drill bit (0.086" diameter) and features an 82° countersink angle. The product is manufactured to precise specifications for reliable performance and is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant.
