S-99512A647 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in various industrial environments.
• Enhanced torque transmission and reduced cam-out thanks to the T27 Torx drive, providing reliable and efficient installation.
• Secure, vibration-resistant fastening in plastic materials due to the tri-lobe shank design, which forms strong threads without pre-drilled tapping.
• Full-length threading for maximum grip and load distribution, ideal for demanding plastic assembly applications.
• Compliance with RoHS 3 and REACH standards, ensuring environmental safety and regulatory adherence for global supply chains.
• Precision-engineered dimensions, including a 1" length and 0.216" thread diameter, for consistent fit and reduced assembly errors.
• Optimized for use with a No. 7 drill bit, simplifying installation and improving efficiency in high-volume production settings.

Professional Applications & Engineering Value

These No. 12 zinc-plated steel TRS thread forming screws are specifically engineered for plastic fastening applications, addressing common challenges like material cracking and loosening under stress. The tri-lobe shank cross-section displaces plastic material during installation, creating robust, permanent threads that enhance pull-out strength and resist vibration. Combined with the T27 Torx drive, these screws deliver high torque transmission with minimal tool wear, reducing assembly time and improving reliability in automotive, electronics, and consumer goods manufacturing. The fully threaded design and blunt tip ensure easy starts and uniform stress distribution, making them ideal for securing plastic housings, brackets, and components without the need for additional inserts or adhesives.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.216" and approximately 11 threads per inch, ensuring precise fit in pre-drilled holes (recommended No. 7 drill bit, 0.201" diameter). The TRS thread forming design and right-hand threading comply with industry practices for plastic assembly. All screws are manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming they are free of hazardous substances and suitable for use in regulated markets.
