S-94060A257 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Self-drilling tip eliminates pre-drilling - Saves time and labor costs by drilling and tapping in one operation through up to 0.09" thick steel and sheet metal
• Zinc-plated steel construction - Provides excellent corrosion resistance for durable performance in industrial environments
• Thread-forming BSD design - Creates stronger, more secure threads that resist vibration loosening and offer superior holding power
• Phillips No. 2 drive system - Ensures reliable torque transfer and prevents cam-out during installation for efficient assembly
• Fully threaded 1-1/4" length - Maximizes thread engagement and clamping force across the entire fastened joint
• Standard pan head profile - Offers a balanced combination of low profile and sufficient bearing surface for secure fastening
• RoHS 3 compliance - Meets environmental safety standards for use in regulated industries and applications

Professional Applications & Engineering Value

These No. 6 self-drilling tapping screws are engineered specifically for steel and sheet metal applications where efficiency and reliability are critical. The integrated drilling tip (No. 2 type) eliminates the need for separate drilling operations, significantly reducing assembly time while maintaining precision. Made from zinc-plated steel, these BSD thread-forming screws create their own threads as they're installed, resulting in tighter fits and superior resistance to vibration compared to conventional fasteners. The Phillips drive ensures consistent installation torque, while the 0.138" thread diameter with 20 threads per inch provides optimal thread engagement for secure connections in HVAC systems, electrical enclosures, and metal fabrication projects.

Specification Summary & Compliance

These self-drilling tapping screws feature a No. 6 screw size with 1-1/4" length and 0.138" thread diameter with approximately 20 threads per inch. The thread-forming BSD tapping method with right-hand thread direction ensures precise thread engagement. Manufactured to industry standards for tapping screws, these fasteners are RoHS 3 (2015/863/EU) Compliant, meeting environmental regulations for hazardous substance restrictions in electronic and industrial applications.
