S-91515A760 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior load distribution with wide truss head and integrated flange design, preventing pull-through in thin materials
• Exceptional corrosion resistance through zinc-plated steel construction, ensuring long-term reliability in harsh industrial environments
• Efficient installation with No. 3 drill tip that penetrates up to 1/4" thickness without pre-drilling, reducing assembly time
• Maximum holding power from fully threaded thread-forming design that creates strong, permanent fastenings in steel and sheet metal
• Enhanced driving control with Phillips No. 3 drive that minimizes cam-out and provides secure torque transmission
• Reliable performance with BSD thread forming technology that ensures tight, vibration-resistant connections
• Environmental compliance meeting RoHS 3 standards for safe, sustainable manufacturing practices

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional engineering value in demanding sheet metal and steel applications where vibration resistance and structural integrity are critical. The thread forming BSD design creates precise mating threads in parent material without chip formation, eliminating contamination risks in electrical enclosures, HVAC systems, and automotive assemblies. The combination of flanged truss head and fully threaded shank provides superior clamp force distribution across wider surface areas, preventing material distortion in thin-gauge applications. With No. 3 drill tip technology, these screws penetrate up to 1/4" thickness while maintaining thread integrity, significantly reducing installation time and labor costs in high-volume production environments.

Specification Summary & Compliance

These 1/4"-14 thread forming tapping screws feature precision right-hand threads with industry-standard BSD tapping screw specifications. The zinc-plated steel construction ensures consistent performance with Class 2A thread tolerances for reliable engagement. Manufacturing complies with RoHS 3 (2015/863/EU) environmental standards, guaranteeing restriction of hazardous substances. The Phillips No. 3 drive and 0.521" flange diameter provide standardized installation compatibility across industrial applications.
