S-90286A301 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power with 0.432" flange diameter that distributes load evenly and prevents pull-through in sheet metal applications
• Efficient thread forming design creates strong, permanent threads in sheet metal without chips or debris
• External hex/slotted drive combination provides versatile installation options for various tool types and torque requirements
• Fully threaded 2" length ensures maximum engagement and holding strength throughout the entire fastener length
• Precision pointed tip enables easy starting and accurate alignment with 3/16" pre-drilled holes
• Environmental compliance assurance with RoHS 3 and REACH compliance for safe use in regulated industries
• Right-hand threading with 11 TPI delivers reliable, consistent performance in high-vibration environments

Professional Applications & Engineering Value

These No. 12-11 thread forming tapping screws are specifically engineered to address common challenges in sheet metal fabrication and assembly. The Type A thread forming design eliminates the need for tapping operations by cold-forming mating threads directly into the base material, creating stronger thread engagement than cut threads. The hex head with external drive accommodates high torque applications while the integrated flange provides superior bearing surface, reducing the risk of material deformation under load. The fully threaded configuration ensures consistent clamping force distribution, making these sheet metal fasteners ideal for HVAC systems, electrical enclosures, automotive components, and industrial machinery where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

These thread forming tapping screws feature precision No. 12-11 thread with 0.216" thread diameter and 2" length, designed with hex head (0.313" width, 0.194" height) and 0.432" flange diameter. The pointed tip facilitates easy insertion into 3/16" (0.1875") pre-drilled holes in materials up to 0.025" thickness. Manufactured to Type A tapping screw standards with right-hand threading and fully threaded shank. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
