Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated 410 stainless steel construction, ideal for harsh industrial environments
- Integrated sealing washer prevents leakage and provides vibration-resistant, weather-tight connections
- Self-drilling tip eliminates pre-drilling, saving labor time and reducing installation costs in stainless steel and sheet metal
- Full 18 TPI threading ensures maximum grip and pull-out strength in thin materials up to 0.098" thickness
- External hex drive design allows for high-torque application with standard tools, preventing cam-out
- Thread forming (BSD) design creates strong, strip-resistant threads without generating chips
- Precision flat washer distributes load evenly, protecting material surfaces from damage
Professional Applications & Engineering Value
These No. 8 zinc-plated 410 stainless steel tapping screws solve critical fastening challenges in stainless steel and sheet metal applications. The combination of thread forming technology and drilling tip eliminates the need for separate drilling operations, significantly reducing assembly time while creating durable, vibration-resistant connections. The fully threaded design with 18 TPI provides maximum engagement in thin materials, while the integrated sealing washer with stainless steel/rubber construction ensures environmental protection against moisture and contaminants. These external hex drive screws deliver reliable performance in HVAC, electrical enclosures, and metal fabrication where corrosion resistance and sealing integrity are paramount.
Specification Summary & Compliance
Manufactured to precise dimensional standards with 0.164" thread diameter and 1-1/4" length, these BSD tapping screws feature Class 2A thread tolerances for consistent performance. The flat washer measures 1/2" OD with stainless steel/rubber construction. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial durability standards are met for global applications.
