S-90197A245 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in demanding industrial environments
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor costs
• Dual drive capability with external hex/slotted head provides versatile installation options for various tool types and access situations
• Enhanced load distribution through the integrated flange design prevents pull-through and improves joint integrity
• Precision needle point facilitates easy starting and accurate alignment, minimizing material damage during installation
• Full threading along the 3/4" length ensures maximum grip and uniform stress distribution across the entire fastened area
• Environmental compliance meets RoHS 3 and REACH standards, making them suitable for regulated industries and export markets

Professional Applications & Engineering Value

These No. 10-12 thread forming tapping screws are specifically engineered to address common challenges in sheet metal fabrication and assembly. The zinc-plated steel construction provides excellent corrosion protection while maintaining high tensile strength, crucial for maintaining joint integrity in vibration-prone applications. The thread forming design eliminates the need for separate tapping operations, significantly reducing assembly time and costs while creating stronger threads that won't strip under stress. The combination of external hex drive and flanged head ensures secure installation with standard tools while distributing clamping force effectively across thin sheet materials. These features make them ideal for HVAC systems, electrical enclosures, automotive components, and industrial equipment where reliable metal-to-metal fastening is critical for performance and safety.

Specification Summary & Compliance

These tapping screws feature precise No. 10-12 thread specifications with 12 threads per inch and 0.19" thread diameter, designed for use with No. 21 drill bit (0.159" diameter) in materials up to 0.05" thickness. The hex head measures 1/4" across flats with 0.141" height, while the flange diameter extends to 0.348" for superior load distribution. Manufactured to industry standards for thread forming screws, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the strictest international requirements for hazardous substance restrictions.
