Professional Applications & Engineering Value

These 18-8 stainless steel Phillips flat head tapping screws are specifically engineered for demanding sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming technology eliminates the need for separate tapping operations, creating strong, vibration-resistant threads that won't loosen under stress. The fully threaded design ensures maximum surface contact and load distribution, while the standard 82° countersink angle provides seamless integration with metal surfaces. Ideal for HVAC systems, electrical enclosures, automotive panels, and industrial equipment, these Type A tapping screws deliver reliable performance in environments where thermal cycling, moisture, and mechanical stresses would compromise inferior fasteners.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.164" thread diameter and 15 threads per inch in right-hand configuration. Features Class 2A thread tolerances for reliable fit and performance. The flat head design with standard profile and No. 2 Phillips drive ensures compatibility with industry-standard installation tools. Complies with relevant industrial standards for tapping screw applications and manufactured from RoHS and REACH compliant 18-8 stainless steel materials for environmental safety and workplace compliance.
