S-94625A427 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance through zinc-plated steel construction for extended service life in demanding industrial environments
• Superior tamper-resistant security with T20 Torx drive design to prevent unauthorized access in sensitive applications
• Efficient self-drilling capability with integrated drilling tip that eliminates pre-drilling requirements for materials up to 0.15" thick
• Optimal flush mounting featuring standard flat head profile with 82° countersink angle for smooth, professional finishes
• Reliable thread-forming performance with B-type tapping design that creates strong, permanent threads in steel and sheet metal
• Full-length threading ensures maximum grip and load distribution across the entire 2" fastener length
• Precise No. 10-16 thread configuration delivers consistent engagement and clamping force in industrial assemblies

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional value in metal fabrication and industrial assembly applications. The thread-forming B-type design creates durable, vibration-resistant threads in steel and sheet metal without requiring pre-tapped holes, significantly reducing installation time and labor costs. The integrated drilling tip efficiently penetrates materials up to 0.15" thick, while the tamper-resistant T20 Torx drive provides security in public-facing or restricted access installations. The 82° countersink angle ensures proper seating in standard chamfered holes, creating flush surfaces that prevent snagging and improve aesthetic appeal in finished products. These fully threaded screws maintain consistent clamping force across the entire fastener length, making them ideal for HVAC systems, electrical enclosures, machinery guards, and structural metal assemblies where reliability and security are paramount.

Specification Summary & Compliance

Manufactured to precise dimensional standards with No. 10-16 UNC thread specifications (0.19" thread diameter, 16 TPI) and right-hand thread direction. Features include standard flat head profile (0.362" diameter, 0.116" height), T20 tamper-resistant Torx drive, and No. 3 drilling tip (1/4" length). The thread-forming tapping method (Type B) complies with industry standards for metal fastening applications. Zinc-plated steel construction provides corrosion protection while meeting RoHS and REACH compliance requirements for industrial use.
