Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
- Efficient self-drilling capability with a No. 2 drill tip and 7/32" length, eliminating the need for pre-drilling in steel and sheet metal up to 0.1" thickness.
- Secure, flush installation thanks to the oval head design and 82° countersink angle, providing a smooth finish and reduced snagging.
- Reliable thread forming with BSD tapping method, creating strong, vibration-resistant threads in base materials without chips.
- Easy installation and removal with Phillips No. 2 drive, ensuring compatibility with common tools and reducing slippage.
- Full-length threading for maximum grip and holding power across the entire 1-1/2" length in various material thicknesses.
- Compliance with environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industrial applications.
Professional Applications & Engineering Value
These No. 8 x 1-1/2" stainless steel oval head tapping screws are engineered to address common challenges in steel and sheet metal fabrication, such as time-consuming pre-drilling and corrosion-induced failure. The 18-8 stainless steel material offers excellent resistance to rust and oxidation, extending service life in demanding conditions. The integrated No. 2 drill tip and thread forming (BSD) design allow for quick, one-step installation, reducing labor costs and improving assembly efficiency. The fully threaded shank and oval head with an 82° countersink ensure a secure, flush fit, minimizing protrusion and enhancing safety in construction, HVAC, and industrial equipment applications.
Specification Summary & Compliance
This screw features a thread diameter of 0.164" with approximately 18 threads per inch, adhering to standard inch measurements for consistent performance. The oval head profile and Phillips drive are designed for reliable fastening in steel and sheet metal. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for industrial use without hazardous substances.
