S-91515A910 Length 4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Efficient installation through self-drilling tip design that eliminates pre-drilling requirements in steel and sheet metal applications
• Enhanced load distribution with wide truss head and integrated flange, preventing pull-through and material damage
• Reliable thread formation using BSD thread forming technology that creates strong, permanent threads in base materials
• Optimized drive engagement with Phillips No. 2 drive system, reducing cam-out and ensuring secure fastening
• Maximum thread engagement through fully threaded 4" length, providing superior holding power in thick materials
• Environmental compliance meeting RoHS 3 standards, ensuring safe use in regulated applications

Professional Applications & Engineering Value

Engineered for steel and sheet metal fabrication, these No. 10-16 tapping screws deliver exceptional value in industrial assembly operations. The zinc-plated steel construction provides reliable corrosion protection while the thread forming BSD design creates durable, vibration-resistant connections without chip formation. The integrated drilling tip penetrates up to 0.175" thickness, eliminating secondary drilling operations and reducing installation time by up to 50%. The flanged truss head distributes clamping force across a wider surface area (0.433" diameter), preventing material distortion in thin-gauge applications. These Phillips drive screws are specifically optimized for high-volume production environments where speed, reliability, and RoHS 3 compliance are critical requirements.

Specification Summary & Compliance

This tapping screw features precise 0.19" diameter threads with 16 threads per inch in right-hand orientation, manufactured to BSD thread forming standards. The 4" fully threaded design ensures maximum engagement depth while the Class 2A thread tolerance provides consistent installation performance. Compliance with RoHS 3 (2015/863/EU) regulations guarantees environmental safety, making these screws suitable for regulated industries and international supply chains. The combination of zinc plating surface treatment and steel material delivers optimal corrosion resistance for industrial applications.
