Professional Applications & Engineering Value

These 410 Stainless Steel tapping screws are specifically engineered for plastic fastening applications where material integrity and corrosion resistance are critical. The DST thread forming technology eliminates the need for pre-tapped holes, creating strong, vibration-resistant threads that won't strip or crack plastic substrates. The Phillips pan head design provides excellent drive engagement while maintaining a low profile for space-constrained assemblies. With 24 threads per inch and 0.112" thread diameter, these screws deliver superior holding power in thermoplastics, composites, and other plastic materials commonly used in industrial applications, electronic enclosures, automotive components, and consumer products requiring durable fastening solutions.
