S-90048A249 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding industrial environments
• Effortless installation through thread forming technology that creates strong, permanent threads without pre-tapping in sheet metal
• Secure flush finishing with standard 82° flat head profile that sits perfectly countersunk for smooth surface applications
• Maximum grip strength with fully threaded design providing consistent holding power along the entire 1-1/4" length
• Reliable drive performance featuring Phillips No. 2 drive for controlled torque application and reduced cam-out risk
• Precision compatibility with No. 21 drill bit (0.159" diameter) for optimal hole preparation in sheet metal up to 0.025" thickness
• Environmental compliance meeting RoHS 3 and REACH standards for safe, sustainable manufacturing practices

Professional Applications & Engineering Value

These No. 10-12 thread forming screws deliver exceptional value in sheet metal applications where vibration resistance and permanent fastening are critical. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the A/AB tapping screw design with 12 threads per inch creates durable, strip-resistant threads in base materials. The Phillips flat head configuration ensures flush mounting in assemblies where protruding fasteners are unacceptable. Engineered specifically for sheet metal fastening, these screws eliminate the need for separate tapping operations, reducing installation time and labor costs while maintaining consistent clamping force in high-vibration settings common to HVAC, electrical enclosures, and metal fabrication projects.

Specification Summary & Compliance

This fully threaded tapping screw features precision right-hand threads with standard inch measurements, including No. 10 screw size, 1-1/4" length, and 0.19" thread diameter. The manufacturing adheres to industry standards for thread forming screws with pointed tip design for easy starting. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. The 82° countersink angle matches standard drill bit preparations for optimal seating in sheet metal applications.
