S-92470A354 Length 19 mm DIN 7981 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments.
• Efficient thread forming design creates strong, permanent threads in sheet metal, eliminating the need for pre-tapped holes.
• High torque transmission via No. 1 Phillips drive, reducing cam-out risk and enabling secure, efficient installation.
• Optimized for 0.025" material thickness, providing maximum holding power in standard sheet metal applications.
• Coarse thread spacing ensures rapid installation and superior pull-out resistance in ductile materials.
• Fully threaded shank distributes clamping force evenly along the entire engagement length.
• DIN 7981 compliance guarantees dimensional accuracy and interchangeability for global manufacturing standards.

Professional Applications & Engineering Value

This M2.9 tapping screw delivers exceptional value in sheet metal assembly where corrosion resistance and installation efficiency are critical. The 18-8 stainless steel composition withstands exposure to moisture, chemicals, and temperature variations, making it ideal for industrial fastening in HVAC, electronics enclosures, and automotive components. The thread forming action cold-works the base material, creating stronger thread engagement than cutting screws while eliminating chip removal issues. With coarse thread spacing and fully threaded design, it achieves faster installation cycles and superior vibration resistance compared to machine screws requiring tapped holes. The pan head profile provides a low-profile bearing surface that distributes clamp load effectively without sinking into thinner materials.

Specification Summary & Compliance

Manufactured to DIN 7981 specifications with ISO-compliant metric dimensions including M2.9 thread diameter, 19mm length, 5.6mm head diameter, and 2.2mm head height. Features Class 2A thread tolerances for reliable engagement in thread forming applications. The right-hand coarse thread configuration follows international standards for sheet metal fasteners. 18-8 stainless steel composition complies with RoHS and REACH environmental directives, ensuring suitability for regulated industries.
