• Excellent corrosion resistance provided by 18-8 stainless steel construction, ensuring long-term durability and reduced maintenance in harsh or humid conditions.
• Efficient thread forming design (Type B) creates strong, precise threads in sheet metal without pre-tapping, reducing installation time and tooling requirements.
• Secure and easy driving with a No. 2 Phillips pan head, offering a flush finish and improved torque transfer for consistent fastening in confined spaces.
• Reliable dimensional accuracy with a 0.164" thread diameter and 18 TPI, ensuring consistent fit and performance in standard No. 29 drill bit-prepared holes.
• Full regulatory compliance with RoHS 3 and REACH standards, guaranteeing safe, environmentally responsible materials for global industrial supply chains.
• Versatile sheet metal application with a 3/8" fully threaded blunt tip design, providing strong holding power and seamless integration in assemblies.

Professional Applications & Engineering Value

This 18-8 stainless steel tapping screw is engineered to address common challenges in sheet metal fabrication, such as fluid ingress and vibration-induced loosening. The thread forming technology eliminates the need for separate tapping operations, reducing labor costs and potential errors while creating robust, strip-resistant threads. Combined with the rubber O-ring seated under the pan head, it delivers a dependable seal that prevents leaks in enclosures, HVAC systems, and electronic housings exposed to moisture or dust. The corrosion-resistant material ensures longevity in demanding environments, from outdoor equipment to chemical processing units, making it a cost-effective solution for maintenance-free, high-performance assemblies.

Specification Summary & Compliance

This screw features a No. 8-18 thread with a 0.164" diameter and 18 TPI, adhering to standard inch measurements for precise fit. The Type B thread forming design and fully threaded 3/8" length provide consistent engagement in pre-drilled holes (recommended No. 29 drill bit, 0.136" diameter). It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring the use of safe, restricted-substance-free materials for industrial applications.
