S-90769A128 Length 25 mm DIN 7504 N, ISO 7049 Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling with an integrated 8.7mm drill tip, saving time and labor costs in assembly operations.
• Superior corrosion resistance provided by the zinc-plated steel construction, ensuring long-term durability in various environments.
• Exceptional holding power achieved through the thread-forming design and fully threaded shank, creating secure, vibration-resistant fastenings.
• Broad material compatibility allows for reliable use in steel, stainless steel, aluminum, sheet metal, wood, fabric, and insulation.
• Optimized for high-speed driving with the Phillips No. 2 drive, reducing cam-out and improving installation efficiency.
• Guaranteed dimensional precision and performance consistency by conforming to the stringent DIN 7504 N standard.
• Safe for regulated industries with full compliance to RoHS 3 and REACH environmental directives.

Professional Applications & Engineering Value

This M4.2 metric tapping screw is engineered to solve the common industrial challenge of joining dissimilar or thin materials without pre-tapped holes. The zinc-plated steel material offers a robust balance of strength and corrosion protection, ideal for sheet metal, enclosures, and frameworks. Its thread-forming technology displaces material to create strong, permanent threads in steel, aluminum, and stainless steel, eliminating the risk of loose fasteners from vibration. The fully threaded design and sharp drill tip ensure rapid penetration and maximum thread engagement up to 3mm thickness, streamlining production in HVAC, automotive, and electrical panel assembly. This combination delivers reduced installation time, lower total cost, and reliable performance in demanding industrial applications.

Specification Summary & Compliance

This screw features a Metric M4.2 diameter with an approximate thread pitch of 1.4mm and a minimum thread length of 16.3mm. The right-hand thread and fully threaded shank are manufactured to precise dimensional standards. It conforms to the performance and quality requirements of DIN 7504 N and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets international safety and environmental standards for industrial components.
