S-91515A330 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated drilling tip that penetrates up to 0.175" thickness in steel and sheet metal
• Superior corrosion resistance through zinc-plated steel construction for extended service life in industrial environments
• Enhanced driving stability with Phillips No. 2 drive system that reduces cam-out and improves installation efficiency
• Optimized load distribution through wide truss head design with 0.433" flange diameter for secure fastening in thin materials
• Reliable thread-forming performance with BSD tapping technology that creates strong, permanent threads in parent material
• Full-length threading ensures maximum grip and holding power across the entire 2-1/2" length
• Environmental compliance assurance with RoHS 3 (2015/863/EU) compliance for sustainable manufacturing operations

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional value in steel and sheet metal applications where traditional fastening methods prove inefficient. The innovative thread forming technology combined with a specialized drilling tip eliminates the need for separate drilling operations, significantly reducing assembly time and labor costs. The BSD tapping screw design creates precise, durable threads that resist vibration loosening, while the wide truss head profile provides superior clamping force distribution, preventing material deformation in thin-gauge metals. Engineered for industrial assembly lines and metal fabrication environments, these fully threaded screws maintain consistent performance across repetitive installation cycles, making them ideal for high-volume production settings requiring reliable, repeatable fastening solutions.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.19" thread diameter and 16 threads per inch for consistent engagement. Features right-hand threads with thread forming tapping method (BSD type) that ensures secure fastening without pre-tapped holes. The zinc-plated steel construction provides both corrosion protection and mechanical strength. Compliant with RoHS 3 (2015/863/EU) environmental regulations, ensuring safe use in various industrial applications. The Phillips No. 2 drive system offers standardized installation compatibility across common driving tools.
