Professional Applications & Engineering Value
This Grade 8 hex flange screw delivers exceptional engineering value through its zinc yellow-chromate plated steel construction, providing superior protection against corrosion in industrial environments. The 3/8"-16 UNC coarse thread with Class 3A precision ensures rapid installation and reliable performance in vibration-prone applications such as heavy machinery, structural frameworks, and automotive assemblies. The integrated flange design distributes clamping force over a wider surface area (13/16" diameter), preventing surface damage and maintaining joint integrity. With 150,000 PSI tensile strength and Rockwell C32 hardness, this fully threaded fastener maintains critical connections in high-load scenarios where failure is not an option, making it ideal for construction equipment, manufacturing systems, and transportation infrastructure.
Specification Summary & Compliance
This heavy-duty fastener features precise Class 3A thread fit with UNC coarse thread spacing (3/8"-16) and meets IFI 111/SAE J429 specifications for Grade 8 fasteners. The 1 1/2" length and 13/16" flange diameter provide dimensional consistency for reliable assembly. Manufactured from high-strength steel with zinc yellow-chromate plating for corrosion protection, this screw maintains compliance with industrial standards for mechanical properties and surface treatment requirements.
