S-92727A140 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with Black-Oxide coated 18-8 Stainless Steel, ensuring long-term reliability in harsh environments
• Enhanced torque transmission and reduced cam-out thanks to the Torx T10 drive, allowing for precise installation and higher tightening forces
• Secure, vibration-resistant fastening in plastics due to the thread-forming Tri-Lobe shank design, which creates strong, durable threads without pre-tapping
• Consistent, full-length engagement with fully threaded design, providing uniform clamping force along the entire screw length
• Optimized for plastic assemblies with a blunt tip and right-hand thread, minimizing material stress and cracking during installation
• Environmental compliance assurance meeting RoHS 3 and REACH standards, making it suitable for regulated industries and global supply chains
• Precision fit and reduced installation errors with standardized No. 4-20 thread size and compatible No. 37 drill bit, ensuring repeatable performance

Professional Applications & Engineering Value

This No. 4-20 TRS tapping screw is engineered to address common challenges in plastic assembly, such as strip-out, material fatigue, and corrosion. The Black-Oxide 18-8 Stainless Steel construction provides excellent resistance to oxidation and chemicals, extending service life in industrial settings. Its thread-forming Tri-Lobe shank displaces plastic material to form precise, strong threads, eliminating the need for separate tapping operations and reducing assembly time. The Torx T10 drive ensures efficient torque transfer, minimizing tool slippage and damage to the screw head, which is critical for high-volume production lines. Ideal for securing plastic components in electronics, automotive trim, and consumer goods, this screw delivers reliable performance while complying with stringent environmental regulations like RoHS and REACH.

Specification Summary & Compliance

This screw adheres to inch system measurements with a thread diameter of 0.112" and 20 threads per inch, ensuring precise fit in plastic applications. It features a Class 2A thread tolerance for consistent engagement and a pan head style for flush or low-profile mounting. Manufactured to industry standards for thread-forming tapping screws (TRS type), it is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing safety and environmental responsibility in industrial use.
