Professional Applications & Engineering Value

This No. 14 zinc-plated steel tapping screw delivers exceptional value in plastic assembly applications where material integrity and secure fastening are critical. The DST thread forming technology eliminates the risk of plastic cracking by displacing material rather than cutting it, creating stronger threads that resist vibration loosening. The Phillips drive system ensures reliable torque transfer while the fully threaded design maximizes engagement in various plastic thicknesses. Engineered specifically for plastic fastening applications, this screw prevents stress concentration points that can lead to material failure, making it ideal for electronic enclosures, automotive trim, consumer products, and industrial equipment where plastic components require durable, vibration-resistant fastening solutions.

Specification Summary & Compliance

This precision fastener features a 0.242" thread diameter with 15 threads per inch and 3/8" length in a fully threaded configuration. The screw meets ASME B18.6.3 specifications for dimensional accuracy and performance standards. Manufactured from zinc-plated steel with a standard pan head profile (0.492" diameter, 0.175" height) and Phillips No. 3 drive. Designed for use with No. 7 drill bit (0.201" diameter) in plastic materials, ensuring proper hole sizing for optimal thread forming performance. The right-hand threading and blunt tip design provide consistent, reliable installation in various plastic substrates.
