S-90190A103 Length 3/16" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction, ensuring long-term durability in industrial environments.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing assembly time and labor costs.
• Secure Phillips drive (No. 1 size) provides reliable torque transmission and minimizes cam-out risks during installation.
• Fully threaded shank and pointed tip allow for quick, self-starting penetration and maximum grip in materials up to 0.025" thickness.
• Standard pan head profile offers a low-profile finish with good bearing surface for stable fastening in sheet metal applications.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and meets global industry standards for hazardous substances.
• Precise compatibility with No. 44 drill bits and 24 TPI thread pitch for consistent performance in metalworking and construction projects.

Professional Applications & Engineering Value

These No. 4 Phillips tapping screws are engineered to address common challenges in sheet metal assembly, such as material splitting and loose fasteners. The thread forming (Type A/AB) design displaces material rather than cutting it, creating robust threads that resist vibration and pull-out forces. Made from zinc-plated steel, they provide excellent shear strength and corrosion protection, ideal for HVAC systems, electronic enclosures, and automotive components. The fully threaded body and pointed tip enable quick starts without pilot holes, streamlining production lines and reducing installation errors. By integrating these tapping screws into your processes, you achieve reliable, high-strength joints that maintain integrity under stress, enhancing overall project longevity.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a thread diameter of 0.112" and length of 3/16", featuring a Class 2A thread fit for consistent engagement. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no restricted substances are used. The thread forming tapping method and right-hand threading align with industry norms for sheet metal fasteners, providing reliable performance in applications requiring precision and durability.
