Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh environments.
- Efficient thread-forming design (Type A) creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time.
- Optimized for 0.025" maximum drilling thickness, providing secure fastening in standard sheet metal applications.
- Phillips No. 2 drive and standard 82° flat head allow for flush mounting and easy installation with common tools.
- Fully threaded shank delivers maximum grip and holding power along the entire 1-1/4" length.
- Compliance with RoHS 3 and REACH regulations ensures environmental safety and suitability for global industrial markets.
- Precise compatibility with No. 21 drill bit (0.159" diameter), facilitating accurate and hassle-free hole preparation.
Professional Applications & Engineering Value
These No. 10-12 thread-forming screws are engineered to address common challenges in sheet metal assembly, such as material fatigue and corrosion. The 18-8 stainless steel composition provides excellent resistance to rust and oxidation, making them ideal for outdoor equipment, HVAC systems, and electronic enclosures. The Type A tapping method and fully threaded design ensure a tight, vibration-resistant fit without the need for additional locking mechanisms, reducing labor costs and improving assembly line efficiency. With a standard 82° flat head profile, they sit flush against surfaces, preventing snagging and maintaining a clean aesthetic in finished products.
Specification Summary & Compliance
This screw adheres to standard inch measurements with a thread diameter of 0.19" and 12 threads per inch, ensuring precise fit in pre-drilled holes. It features a right-hand thread direction and fully threaded shank for consistent performance. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming the absence of hazardous substances and alignment with international environmental and safety standards for industrial fasteners.
