S-99512A649 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with T27 Torx drive prevents cam-out and tool slippage during installation
• Excellent corrosion resistance through zinc-plated steel construction for extended service life in various environments
• Vibration-resistant fastening achieved through Tri-Lobe shank design that creates secure, permanent threads in plastic materials
• Reduced installation stress with thread-forming TRS design that eliminates chip formation and material damage
• Enhanced grip surface from the pan head profile provides better contact area for secure fastening applications
• Consistent performance with fully threaded design ensuring uniform load distribution along the entire fastener length
• Environmental compliance meeting RoHS 3 and REACH standards for responsible manufacturing and usage

Professional Applications & Engineering Value

These No. 12 x 1-1/2" tapping screws are specifically engineered for plastic fastening applications where traditional fasteners fail. The thread-forming TRS design with Tri-Lobe shank cross-section displaces plastic material during installation, creating strong, permanent threads without generating chips or debris that could compromise electronic components. This makes them ideal for plastic assembly in automotive trim, electrical enclosures, and consumer electronics where vibration resistance is critical. The zinc-plated steel construction provides essential corrosion protection while maintaining the strength needed for durable plastic connections. The T27 Torx drive system ensures high torque transmission without stripping, reducing installation errors and improving production efficiency in automated or manual assembly processes.

Specification Summary & Compliance

These thread forming screws feature precise 0.216" thread diameter with 11 threads per inch and 1-1/2" length for consistent performance. The TRS tapping screw type with right-hand thread direction and blunt tip is designed for use with No. 7 drill bit (0.201" diameter) in plastic materials. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe usage across various industrial applications.
