Key Features & Benefits at a Glance

  • Superior plastic retention through thread forming technology that creates strong, permanent threads without chips or debris
  • Excellent corrosion resistance provided by 410 stainless steel construction for long-lasting performance in various environments
  • Quick and secure installation with Phillips No. 2 drive that prevents cam-out and ensures consistent torque application
  • Optimized plastic penetration featuring a fully threaded pointed tip that initiates threading easily and maintains grip
  • Reliable fastening performance with standardized No. 8 size and 2" length for consistent results across multiple applications
  • Streamlined assembly process using pre-determined No. 29 drill bit (0.136") for perfect hole preparation
  • Enhanced load distribution from the pan head design that provides a larger bearing surface for secure fastening

Professional Applications & Engineering Value

These 410 stainless steel tapping screws are specifically engineered for plastic assembly challenges where traditional fasteners fail. The thread forming technology eliminates the risk of plastic cracking or stress fractures by displacing material rather than removing it, creating stronger thread engagement that resists vibration-induced loosening. The fully threaded pointed tip ensures immediate engagement with plastic substrates, while the Phillips drive system provides reliable torque transfer during installation. Ideal for plastic fabrication, electronic enclosures, automotive trim components, and industrial equipment assemblies, these screws maintain integrity in environments where moisture, chemicals, or temperature variations would compromise ordinary fasteners. The combination of corrosion-resistant 410 stainless steel and precision threading delivers consistent performance in high-volume manufacturing applications.

Specification Summary & Compliance

These No. 8 x 2" tapping screws feature a 0.164" thread diameter with 11 threads per inch in right-hand direction, conforming to standard inch system measurements. The thread forming design follows industry standards for plastic fastening applications, requiring a No. 29 drill bit (0.136" diameter) for proper hole preparation. Manufactured from 410 stainless steel with pan head profile and Phillips No. 2 drive, these screws maintain dimensional accuracy suitable for precision assembly operations. The construction meets industry requirements for corrosion resistance and mechanical performance in plastic fastening applications.
