Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for humid or demanding environments.
- Efficient thread forming with TRS tri-lobe shank design eliminates pre-tapping, reducing assembly time and labor costs.
- Secure fastening in plastic through thread forming action that minimizes stress cracking and ensures reliable holding power.
- Easy installation with Phillips No. 1 drive, allowing for quick tool engagement and reduced cam-out during tightening.
- Consistent full-length threading provides uniform load distribution along the entire screw length for enhanced joint integrity.
- Broad industrial compliance with RoHS 3 and REACH regulations, ensuring safe use in global markets.
- Optimized dimensions (No. 2 size, 1/2" length, 28 TPI) deliver precise fit and reliable performance in plastic assemblies.
Professional Applications & Engineering Value
These 18-8 stainless steel tapping screws are engineered specifically for plastic assembly applications, where traditional fasteners may cause material failure. The TRS thread forming design with a tri-lobe shank cross-section displaces plastic material during installation, creating strong, wear-resistant threads without pre-drilled tapping. This eliminates the risk of stress cracking common in brittle polymers, while the Phillips pan head and blunt tip ensure flush seating and easy alignment. Ideal for electronics enclosures, automotive trim, and consumer products, these screws provide vibration resistance and long-term durability in plastic fastening systems, reducing maintenance and improving product lifecycle.
Specification Summary & Compliance
This No. 2 x 1/2" tapping screw features a thread diameter of 0.086" with 28 threads per inch, fully threaded for consistent engagement. Manufactured to standard inch system tolerances with a pan head style and Phillips No. 1 drive, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial suitability for global supply chains.
