Professional Applications & Engineering Value

These 410 stainless steel tapping screws deliver exceptional engineering value in industrial fastening applications where security, corrosion resistance, and installation efficiency are critical. The thread forming A/AB design creates durable, vibration-resistant connections in steel, stainless steel, and sheet metal substrates without tapping operations. The integrated drilling tip eliminates separate drilling steps, reducing installation time by up to 50% while the tamper-resistant Torx T20 drive ensures secure assemblies in public access or high-security environments. With 18 threads per inch and 0.164" thread diameter, these fasteners provide optimal load distribution and pull-out resistance, making them ideal for HVAC systems, electrical enclosures, machinery guards, and architectural metalwork where reliable, permanent fastening is essential.

Specification Summary & Compliance
