Key Features & Benefits at a Glance
- Superior corrosion resistance with specialized coating to extend service life in harsh environments
- Efficient thread forming design creates strong, permanent threads without pre-drilling in steel and sheet metal
- Integrated steel/rubber sealing washer provides reliable moisture and dust protection at installation points
- Self-drilling tip penetrates up to 1/2" thickness, eliminating separate drilling operations
- External hex drive head delivers maximum torque transmission and installation control
- Coarse UNC threading ensures rapid installation and superior holding power in various materials
- Full threading along entire shank provides consistent clamping force throughout the engagement length
Professional Applications & Engineering Value
Engineered for demanding steel and sheet metal applications, these 12-24 UNC tapping screws solve critical installation challenges in industrial assembly. The corrosion-resistant coated steel construction withstands environmental exposure while the thread forming design (CSD type) creates precise mating threads without chip removal, preventing loosening from vibration. The combination of drilling tip and sealing washer streamlines installation by eliminating multiple process steps, reducing labor costs and improving production efficiency in HVAC systems, electrical enclosures, and metal fabrication projects where moisture resistance and structural integrity are paramount.
Specification Summary & Compliance
These 1-1/4" length tapping screws feature No. 12 screw size with UNC coarse threads following standard thread specifications. The external hex drive and fully threaded design ensure proper installation according to industry practices. Manufactured as CSD type thread forming screws with flat washer configuration, these fasteners are RoHS 3 (2015/863/EU) Compliant, meeting environmental regulations for restricted substances while maintaining consistent performance in industrial applications.
