S-94625A131 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Tamper-resistant T27 Torx drive prevents unauthorized removal, enhancing security in public or high-risk industrial environments.
• Zinc-plated steel construction provides excellent corrosion resistance, ensuring long-term reliability in demanding applications.
• Self-drilling tip (No. 3 type) eliminates the need for pre-drilling, saving significant labor time and reducing installation costs in steel and sheet metal.
• Thread forming design creates strong, durable threads in the base material for superior vibration resistance and holding power.
• 82° flat head with standard profile allows for a clean, flush finish, improving aesthetics and safety by preventing snagging.
• Fully threaded shank maximizes grip and clamping force along the entire 1" length for a more secure and reliable fastening.
• Optimized for 0.21" maximum thickness delivers consistent performance and penetration in common sheet metal and light steel gauges.

Professional Applications & Engineering Value

Engineered for efficiency in metalworking, these No. 14 thread forming screws solve critical assembly line challenges. The combination of a specialized drilling tip and zinc-plated steel body allows for direct installation into steel and sheet metal up to 0.21" thick, eliminating separate drilling operations and speeding up production. The tamper-resistant Torx T27 drive is crucial for securing HVAC units, electrical enclosures, and public infrastructure against vandalism. The 82° countersink angle ensures the flat head sits perfectly flush, providing a smooth surface that is both professional and safe. This design is ideal for construction, manufacturing, and MRO applications where durability and security are non-negotiable.

Specification Summary & Compliance
