S-97246A115 1/4"-20 x 6" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated steel drill tip that penetrates up to 1/2" thickness in steel and sheet metal
• Superior corrosion resistance thanks to 18-8 stainless steel construction with galvanic-barrier coating for harsh environments
• Enhanced vibration resistance through thread forming technology that creates stronger, permanent threads in base materials
• High-torque installation capability with external hex drive design for secure fastening in demanding applications
• Distributed load bearing from integrated flange that provides wider surface contact and prevents pull-through
• Reliable coarse thread engagement with UNC 1/4"-20 threading that ensures quick installation in various materials
• Optimized for industrial materials including steel, stainless steel, and sheet metal applications

Professional Applications & Engineering Value

This flanged hex head tapping screw delivers exceptional value in metal fabrication and industrial assembly where drilling and fastening operations are combined. The 18-8 stainless steel core with galvanic-barrier coating provides crucial corrosion protection in demanding environments, while the specialized No. 5 steel drill tip eliminates secondary drilling operations, significantly reducing installation time and labor costs. The thread forming (CSD) design creates stronger, vibration-resistant connections in steel, stainless steel, and sheet metal by displacing material rather than removing it. With partial threading and external hex drive, these screws offer superior clamping force and torque transmission for structural applications requiring reliable, long-lasting fastening solutions.

Specification Summary & Compliance

This 1/4"-20 UNC coarse thread tapping screw features Class 2A thread tolerances and complies with standard industrial fastening specifications. The thread forming technology follows CSD tapping screw standards, while the 18-8 stainless steel material with galvanic-barrier coating meets corrosion resistance requirements for industrial applications. Manufacturing follows quality assurance protocols suitable for structural fastening in metalworking industries, with 6" length and 3/8" hex head dimensions providing consistent performance across production runs.
