S-92470A385 Length 25 mm DIN 7981 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding environments
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-drilling requirements
• Optimized for sheet metal applications with capability to drill through up to 0.025" thickness materials
• Enhanced driving stability with Phillips No. 3 drive that reduces cam-out and improves torque transmission
• Maximum holding power through fully threaded design that ensures complete engagement along the entire fastener length
• Reliable dimensional accuracy meeting DIN 7981 specifications for consistent performance and interchangeability
• Versatile coarse thread pattern provides quick installation and superior pull-out resistance in various metal substrates

Professional Applications & Engineering Value

These M5.5 tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The 18-8 stainless steel composition provides excellent corrosion resistance, making them ideal for applications exposed to moisture, chemicals, or outdoor conditions. The thread forming design eliminates the need for separate tapping operations, reducing installation time and labor costs while creating strong, vibration-resistant connections. The coarse thread configuration ensures reliable performance in thin materials where fine threads might strip or fail. With their fully threaded construction and pointed tip, these screws penetrate smoothly and maintain consistent clamping force across the entire joint, preventing loosening under dynamic loads. The pan head profile with Phillips drive offers a balanced combination of low profile and secure driving capability, perfect for automated assembly systems and high-volume production environments.

Specification Summary & Compliance

These precision metric tapping screws feature M5.5 diameter with 25mm length and comply with DIN 7981 specifications for dimensional accuracy and performance standards. The right-hand thread with coarse spacing ensures proper engagement in sheet metal applications. Manufactured from 18-8 stainless steel, these fasteners meet industry standards for material quality and are compliant with RoHS and REACH environmental regulations. The thread forming design follows established engineering principles for creating durable, permanent threads in metal substrates without additional tapping operations.
