S-90054A252 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced fastening stability through flanged hex head design that distributes load evenly and prevents pull-through
• Efficient thread forming action creates strong, permanent threads in sheet metal without pre-tapping requirements
• Optimal material compatibility with No. 21 drill bit (0.159") for precise installation in sheet metal up to 0.025" thickness
• Maximum driving torque capability with external hex/slotted drive combination for secure installation and removal
• Full-length threading ensures consistent grip along the entire 1-3/4" length for reliable sheet metal fastening
• Regulatory compliance assurance meets RoHS 3 and REACH standards for safe industrial use worldwide

Professional Applications & Engineering Value

These No. 10-12 thread forming screws deliver exceptional performance in sheet metal applications where vibration resistance and long-term reliability are critical. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the flanged hex head design eliminates the need for separate washers, reducing installation time and component count. The thread forming tapping method creates precise, tight-fitting threads that resist loosening under stress, making these fully threaded screws ideal for HVAC systems, electrical enclosures, and metal fabrication projects. With 12 threads per inch and 0.19" thread diameter, they offer optimal balance between installation speed and holding power in thin-gauge materials.

Specification Summary & Compliance

This No. 10 tapping screw features inch system measurements with 1-3/4" length and 0.313" hex head width for standard tool compatibility. The thread forming (Type A/AB) design follows industry standards for sheet metal fastening with right-hand threading and pointed tip for easy starting. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material transparency. The 0.414" flange diameter provides increased bearing surface, while the external hex/slotted drive accommodates multiple installation methods for flexibility in production environments.
