S-94195A361 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-lasting performance in harsh industrial environments.
• Efficient self-drilling capability with integrated No. 2 drill tip, eliminating the need for pre-drilling and reducing assembly time in aluminum and sheet metal.
• Strong, reliable thread engagement through thread forming (BSD) design, creating durable threads that resist loosening under vibration.
• Wide material compatibility for use in aluminum and sheet metal up to 0.08" thickness, providing versatile fastening solutions.
• Secure, flush installation with a standard 82° flat head and Phillips No. 1 drive, offering a clean finish and preventing snagging.
• Full-length threading for maximum grip along the entire 1/2" length, enhancing pull-out strength in thin materials.
• Compliance with strict environmental regulations, meeting RoHS 3 and REACH standards for safe, sustainable industrial use.

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws are engineered to address common challenges in fastening aluminum and sheet metal, where material softness and thin gauges can lead to stripped threads or poor holding power. The thread forming (BSD) design displaces material to create strong, permanent internal threads without cutting, which minimizes chip formation and increases fatigue resistance. Combined with the self-drilling tip, these screws streamline assembly by eliminating separate drilling steps, reducing labor costs and potential alignment errors. The fully threaded No. 4 size with 24 TPI ensures consistent clamping force, making them ideal for HVAC, electronics enclosures, and automotive panels where vibration resistance and a flush finish are critical.

Specification Summary & Compliance

This product features a 0.112" thread diameter with approximately 24 threads per inch and a right-hand thread direction, conforming to standard inch measurements. The flat head with an 82° countersink angle and Phillips drive ensures secure, flush mounting. Manufactured as BSD type thread forming screws, they are fully threaded and include compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they are free of hazardous substances and suitable for global industrial applications.
