S-97972A417 7/16"-14 x 2" Extreme-Strength Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 180,000 PSI ensures reliable performance under heavy loads and reduces the risk of fastener failure in demanding applications
• Black-oxide steel construction provides superior corrosion resistance and enhanced durability in harsh industrial environments
• Rockwell C38 hardness rating delivers excellent wear resistance and maintains thread integrity through repeated installations
• Flanged design with external hex drive eliminates the need for separate washers and provides secure, vibration-resistant fastening with standard tools
• Class 2A thread fit with UNC coarse threading ensures easy installation and reliable performance in a wide range of materials
• Partial threading configuration allows for precise clamping force control and prevents over-tightening in critical assemblies
• Right-hand thread direction with coarse spacing enables quick assembly and disassembly while maintaining secure connections

Professional Applications & Engineering Value

This 7/16"-14 UNC hex head screw delivers exceptional engineering value through its black-oxide steel composition and optimized flange design. The Rockwell C38 hardness ensures the fastener maintains structural integrity in high-vibration environments common in heavy machinery, construction equipment, and industrial assembly applications. The partial threading feature provides controlled clamping force distribution, preventing material damage in precision assemblies while the coarse UNC thread pattern ensures reliable performance in softer materials and faster installation times. The external hex drive combined with the integrated flange creates a secure fastening solution that resists loosening under dynamic loads, making it ideal for automotive, manufacturing, and structural applications where vibration resistance is critical.

Specification Summary & Compliance

This industrial fastener features precise Class 2A thread fit tolerance according to UNC standards, ensuring consistent performance and interchangeability. The 2" length with 1 1/4" minimum thread length provides optimal engagement depth for various material thicknesses. Manufactured to meet industry standards for inch system fasteners, this hex head screw maintains dimensional accuracy with 7/16" thread diameter and 43/64" flange diameter. The product complies with relevant industrial specifications for heavy-duty fasteners and is suitable for applications requiring reliable mechanical performance under demanding conditions.
