S-90056A107 Length 5/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in industrial environments
• Excellent thread-forming capability with Type B design creates permanent, vibration-resistant connections in sheet metal
• Secure installation ensured by Phillips No. 1 drive system preventing cam-out during torque application
• Optimal material displacement from blunt tip design reduces cracking risk in thin sheet metal applications
• Full-length threading provides maximum grip strength across the entire 5/16" engagement length
• Standard pan head profile offers low-profile fastening with good bearing surface for consistent clamping force
• Environmental compliance with RoHS 3 standards ensures safe use across regulated industries

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional performance in sheet metal fabrication and assembly operations. The thread forming Type B design eliminates the need for separate tapping operations while creating strong, strip-resistant threads in ductile metals. The fully threaded configuration and 24 TPI pitch provide maximum engagement in thin materials where pull-out strength is critical. The Phillips drive system ensures reliable installation with standard tools, while the pan head design offers a balanced combination of low profile and adequate drive torque capacity. These self-tapping screws are engineered to solve common challenges in metalworking applications, including vibration loosening, material fatigue, and installation efficiency.

Specification Summary & Compliance
