Key Features & Benefits at a Glance

  • Superior corrosion resistance with Black-Oxide Steel coating, ideal for harsh industrial environments and extended service life.
  • Effortless installation and reduced tool wear thanks to the thread forming design that creates strong threads without pre-tapping.
  • High grip strength and vibration resistance from the fully threaded, 32 TPI design ensuring secure fastening in sheet metal.
  • Compatibility with standard No. 48 drill bits (0.076" diameter) for quick, precise hole preparation and streamlined assembly.
  • Optimized for thin materials with a maximum drilling thickness of 0.025", perfect for lightweight sheet metal applications.
  • Reliable drive engagement with the Phillips No. 1 drive, minimizing cam-out and enhancing torque transfer during installation.
  • Environmentally compliant and safe manufacturing, meeting RoHS 3 standards for use in regulated industries.

Professional Applications & Engineering Value

These No. 2 x 3/8" Phillips Pan Head tapping screws are engineered to address common challenges in sheet metal assembly, such as strip-out and loosening under vibration. The thread forming (Type A/AB) design displaces material to create strong, permanent threads without chips, reducing the risk of contamination in sensitive applications. Made from Black-Oxide Steel, these screws offer enhanced corrosion resistance, crucial for outdoor or humid environments. The fully threaded right-hand configuration and 32 TPI pitch ensure maximum holding power in thin-gauge metals, making them ideal for HVAC, electronics enclosures, and automotive panels where reliability and ease of installation are paramount.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.086" and length of 3/8". It features a Class 2A thread fit for general applications, fully threaded right-hand threading, and is designed as a thread forming tapping screw (Type A/AB). Compliance includes RoHS 3 (2015/863/EU), ensuring the absence of hazardous substances for safe use in various industrial sectors.
