Professional Applications & Engineering Value

These No. 10-12 x 2" zinc-plated steel tapping screws deliver exceptional engineering value in sheet metal fabrication and assembly operations. The thread forming design eliminates the need for separate tapping operations while creating stronger, more reliable threads that resist vibration loosening. The flanged hex head configuration provides superior torque transmission during installation and eliminates the requirement for separate washers, streamlining the assembly process. Manufactured from zinc-plated steel, these fully threaded screws maintain their integrity in environments where moisture and corrosion could compromise fastener performance. The right-hand threading with 12 threads per inch ensures smooth engagement and reliable clamping force in various sheet metal thicknesses, making them ideal for HVAC systems, electrical enclosures, and industrial equipment manufacturing where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

This No. 10 tapping screw features a 0.19" thread diameter with 12 threads per inch and complies with standard inch measurement specifications. The thread forming tapping method (Type A/AB) ensures precise thread engagement without material chips. Manufacturing adheres to industry standards for dimensional accuracy, including the specified head dimensions (0.151" height, 0.313" width) and 2" length. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications.
