S-90190A315 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Efficient thread-forming installation creates strong, permanent threads in sheet metal without pre-tapping, reducing assembly time
• Optimized Phillips drive system (No. 3 size) provides secure tool engagement and prevents cam-out during high-torque applications
• Full threading with pointed tip ensures quick starting and smooth penetration through sheet metal up to 0.025" thickness
• Precision dimensional control with 0.242" thread diameter and 10 threads per inch delivers consistent performance and reliable fastening
• Pan head design offers excellent bearing surface for secure fastening while maintaining a low-profile appearance
• Environmental compliance assurance meets RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliability and installation efficiency are critical. The thread-forming design eliminates the need for separate tapping operations, creating strong internal threads that resist vibration loosening and provide superior pull-out strength. The combination of Phillips drive and pan head configuration ensures optimal torque transmission while the fully threaded construction with pointed tip facilitates quick starts and smooth penetration. Ideal for HVAC systems, electronic enclosures, and automotive assemblies, these A/AB type screws deliver consistent performance when used with recommended 5.5mm (0.2165") drill bits, making them essential for production lines requiring repeatable, high-quality fastening solutions.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.242" thread diameter and 10 threads per inch, these thread forming tapping screws maintain consistent Class 2A tolerance for reliable performance. The A/AB screw type specification ensures proper thread form and engagement characteristics. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and suitability for use in regulated industries, while the zinc-plated finish provides additional corrosion protection for extended service life in various operating conditions.
