S-92470A371 Length 25 mm DIN 7981 Tapping Screws

Key Features & Benefits at a Glance

• Corrosion-resistant performance with 18-8 Stainless Steel construction, ensuring long-term reliability in demanding environments.
• Efficient thread forming design eliminates the need for pre-drilling, reducing installation time and labor costs in sheet metal assemblies.
• Optimized torque transfer via the Phillips No. 2 drive and pan head, minimizing cam-out and enhancing driving precision.
• Full threading and coarse pitch provide superior holding power and rapid insertion in various sheet metal thicknesses.
• Standardized dimensions per DIN 7981 ensure consistent fit and interchangeability in metric-based industrial applications.
• Versatile right-hand threading accommodates common assembly practices, streamlining production workflows.
• Durable pointed tip facilitates accurate alignment and smooth penetration into materials up to 0.025" thick.

Professional Applications & Engineering Value

Engineered for sheet metal fastening, this M4.2 tapping screw addresses critical challenges in industrial assembly, such as vibration resistance and material fatigue. The 18-8 stainless steel offers excellent corrosion resistance, ideal for outdoor equipment, HVAC systems, and electronic enclosures exposed to moisture. Its thread forming tapping method creates strong, load-bearing threads in ductile metals without generating chips, reducing the risk of electrical shorts in sensitive applications. The coarse thread spacing and fully threaded design ensure maximum grip in thin-gauge materials, while the Phillips pan head provides a low-profile, secure finish. Complying with DIN 7981, it delivers predictable performance for high-volume manufacturing and maintenance operations.

Specification Summary & Compliance

This screw features precise metric dimensions, including an M4.2 thread size, 25mm length, 8.2mm head diameter, and coarse thread spacing for reliable engagement. Manufactured to DIN 7981 standards, it ensures consistent quality and dimensional accuracy. The 18-8 stainless steel material supports compliance with RoHS and REACH regulations, promoting environmental safety. Suitable for thread forming in sheet metal up to 0.025" thickness, it meets industry demands for durability and efficiency in right-hand, fully threaded applications.
