S-93880A144 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in harsh industrial environments.
• High-torque installation capability through the combination of external hex and slotted drive, allowing for secure fastening with standard tools.
• Efficient thread-forming design (Type B) creates strong, permanent threads in sheet metal without pre-tapping, reducing assembly time and labor costs.
• Enhanced load distribution from the integrated flange, minimizing surface damage and providing a larger bearing area for secure sheet metal joints.
• Full threading along the 1/4" length ensures maximum grip and pull-out resistance in thin materials, ideal for precision sheet metal work.
• Simplified hole preparation with compatibility for standard No. 32 drill bits (0.116" diameter), streamlining the installation process.
• Blunt tip design prevents material push-out and ensures accurate positioning during thread forming in sheet metal applications.

Professional Applications & Engineering Value

Engineered for demanding sheet metal applications, these No. 6-20 thread forming tapping screws deliver reliable performance where vibration resistance and joint integrity are critical. The zinc-plated steel material provides essential corrosion protection, while the flanged hex head with external hex/slotted drive accommodates high torque without stripping, ensuring consistent clamping force in HVAC, electronic enclosures, and automotive assemblies. The thread forming (Type B) design displaces material to create strong, clean threads without chips, eliminating the need for tapped holes and reducing production costs. Compatible with No. 32 drill bits, these screws simplify installation in thin-gauge metals, offering a cost-effective solution for high-volume manufacturing and maintenance operations.

Specification Summary & Compliance

This flanged hex tapping screw features a No. 6-20 thread with a 0.138" diameter and 20 threads per inch, fully threaded for maximum engagement. Manufactured to standard inch system tolerances with a blunt tip and right-hand thread direction, it ensures precise fit in pre-drilled holes. The product complies with industry standards for thread forming screws and is RoHS and REACH compliant, meeting environmental and safety requirements for industrial use.
