S-94288A416 7/16"-14 x 1 1/2" Extreme-Strength Stainless Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 170,000 PSI ensures reliable performance in high-stress environments, reducing the risk of fastener failure.
• Superior corrosion resistance from 450 Stainless Steel construction extends service life and minimizes maintenance in harsh or outdoor applications.
• Flanged design eliminates the need for a separate washer, providing a larger bearing surface for improved load distribution and faster installation.
• Coarse UNC threading with Class 2A fit offers quick assembly and high resistance to vibration loosening in heavy machinery and structural applications.
• External hex drive allows for high torque application with standard tools, ensuring secure fastening and ease of maintenance.
• Rockwell C38 hardness provides excellent wear resistance and durability, maintaining thread integrity through repeated use.
• Partially threaded shank enables precise clamping force on specific joint sections, enhancing stability in assembled structures.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, this 7/16"-14 UNC hex head screw combines 450 Stainless Steel with a flanged design to address critical engineering challenges. The coarse thread spacing and Class 2A thread fit ensure rapid installation and reliable performance in high-vibration environments such as heavy machinery, construction equipment, and transportation systems. The external hex drive facilitates high-torque tightening with common tools, reducing assembly time while the partial threading allows for optimized clamping where full thread engagement isn't required. This corrosion resistant screw maintains its structural integrity in harsh conditions, making it ideal for outdoor infrastructure, marine applications, and industrial processing equipment where durability and reliability are paramount.

Specification Summary & Compliance

This hex head screw features precise Class 2A thread fit per UNC standards with coarse thread spacing for optimal performance. Manufacturing complies with ASME standards for dimensional accuracy, including thread diameter of 0.4375" and minimum thread length of 1 1/4". The 450 Stainless Steel construction meets industry requirements for corrosion resistance and mechanical properties, with compliance to RoHS and REACH environmental directives for safe use across various industrial sectors.
