S-93880A146 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced holding power through thread-forming technology that creates stronger, more reliable connections in sheet metal applications
• Simplified installation with external hex/slotted drive compatibility for versatile tool options and efficient assembly
• Increased stability from the integrated flange design that provides superior load distribution and prevents pull-through
• Full-thread engagement along the entire 3/8" length ensures maximum grip strength and vibration resistance
• Precision compatibility with No. 32 drill bits (0.116" diameter) for accurate hole preparation and optimal thread formation
• Regulatory compliance with RoHS 3 standards for environmentally responsible manufacturing and industrial safety

Professional Applications & Engineering Value

This No. 6-20 TPI flanged hex tapping screw delivers exceptional performance in sheet metal fastening applications where reliability is critical. The thread-forming Type B design eliminates the need for separate tapping operations by creating precise, permanent threads in pre-drilled holes, significantly reducing assembly time and labor costs. The zinc-plated steel construction provides excellent corrosion protection in industrial environments, while the external hex drive with slotted option offers installation flexibility for various production scenarios. The integrated flange design distributes clamping force evenly, preventing material deformation and maintaining joint integrity under vibration and dynamic loads. These industrial fasteners are engineered to solve common challenges in HVAC systems, electrical enclosures, and metal fabrication where secure, long-lasting connections are essential.

Specification Summary & Compliance
