Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh or humid environments
- Excellent holding power in plastic due to the TRS thread forming design and tri-lobe shank that displaces material without creating chips
- Reduced risk of cam-out and stripped heads with the Phillips drive and No. 1 drive size for secure, efficient installation
- Reliable, consistent fastening ensured by the fully threaded, 28 TPI design for maximum thread engagement
- Broad compatibility with a standard pan head profile and blunt tip for use in various plastic materials
- Simplified installation process as it forms its own mating thread, eliminating the need for a pre-tapped hole
- Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safety and reliability for industrial use
Professional Applications & Engineering Value
This No. 2 x 3/16" tapping screw is engineered to solve critical challenges in plastic assembly. The 316 stainless steel provides exceptional resistance to corrosion and chemicals, making it suitable for demanding environments like marine, chemical processing, and outdoor equipment. The TRS thread forming action and tri-lobe shank cross-section are specifically designed for plastics, creating strong, high-stripping resistance threads without generating swarf that could cause electrical shorts or contamination. This design minimizes stress cracking in brittle plastics and ensures a secure, vibration-resistant fit. The Phillips pan head with a No. 1 drive offers a flush finish and reliable torque transfer, streamlining production in industrial fastener applications from electronics enclosures to automotive plastic components.
Specification Summary & Compliance
This screw features a thread diameter of 0.086" with 28 TPI and a length of 3/16". It is a fully threaded, right-hand thread forming screw (Type TRS) with a standard pan head. The manufacturing and material compliance adhere to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in regulated industries and ensuring environmental safety.
