S-91026A032 7/16"-14 ASTM A194 Hex Nuts

Key Features & Benefits at a Glance

• Superior load distribution thanks to the extra wide hex profile, reducing stress concentration and preventing surface damage during tightening
• Enhanced corrosion resistance provided by the black-oxide steel coating, extending service life in demanding industrial environments
• High tensile strength meeting ASTM Grade 2H requirements, ensuring reliable performance under heavy-duty mechanical loads
• Precision thread engagement with Class 2B fit, facilitating smooth assembly and reducing cross-threading risks
• Robust coarse threading (UNC) enabling faster installation and superior vibration resistance in structural applications
• Compliance with ASTM A194 specifications guaranteeing material quality and manufacturing consistency for critical assemblies
• Environmental regulation adherence through RoHS 3 compliance, supporting sustainable manufacturing practices

Professional Applications & Engineering Value

Engineered for heavy-duty industrial fastening, these 7/16"-14 UNC hex nuts solve critical challenges in construction, machinery, and structural assemblies. The black-oxide steel coating provides essential corrosion protection where moisture or chemical exposure occurs, while the extra wide profile distributes clamping force more effectively across joined surfaces - preventing material deformation in soft substrates. The coarse thread design maintains holding power in high-vibration environments where fine threads might loosen, and the ASTM Grade 2H certification ensures consistent strength for critical connections. These industrial fasteners deliver reliable performance in applications ranging from heavy equipment manufacturing to infrastructure projects where maximum load distribution and long-term durability are paramount.

Specification Summary & Compliance
