Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments.
- Efficient thread forming creates strong, permanent threads in sheet metal, eliminating the need for separate tapping operations.
- Streamlined assembly with a No. 2 Phillips drive for common tool compatibility and reduced cam-out.
- Secure and flush finish thanks to the oval head design and 82° countersink angle for a professional appearance.
- Reliable performance in materials up to 0.025" thick, ensuring consistent holding power in sheet metal applications.
- Full-length threading provides maximum grip and load distribution along the entire shank length.
- Global compliance assurance with RoHS 3 and REACH regulations, meeting international environmental and safety standards.
Professional Applications & Engineering Value
These No. 8 x 1/2" stainless steel oval head tapping screws are precision-engineered for demanding sheet metal applications. The 18-8 stainless steel material offers excellent resistance to rust and corrosion, which is critical for outdoor enclosures, HVAC systems, and electrical cabinets. The thread forming (Type A/AB) design displaces material to create robust, strip-resistant threads without generating chips, making them perfect for blind holes and thin-gauge metals. This eliminates the risk of loose fasteners and reduces assembly time. The combination of a Phillips No. 2 drive and a pointed tip ensures quick starts and efficient driving, enhancing productivity on the production line while the oval head sits flush for a smooth, snag-free surface.
Specification Summary & Compliance
This screw features a thread diameter of 0.164" with approximately 15 threads per inch and is fully threaded for maximum engagement. It is designed for use with a No. 29 drill bit (0.136" diameter) and conforms to standard inch system tolerances for tapping screws. The product is manufactured to be compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for industrial use.
