Professional Applications & Engineering Value

This 3/4"-10 UNC hex head screw delivers critical engineering solutions where corrosion resistance and structural integrity are paramount. The 316 stainless steel composition provides exceptional protection against chloride-induced stress corrosion cracking, making it ideal for marine, chemical processing, and offshore applications. The coarse thread design ensures rapid assembly and superior performance in materials prone to galling, while the partial threading configuration concentrates strength where needed most. With ASTM Grade B8M certification and 75,000 psi tensile strength, this heavy-duty hex bolt withstands extreme mechanical stresses and temperature variations, providing long-term reliability in structural connections, pressure vessels, and industrial machinery where failure is not an option.

Specification Summary & Compliance

This inch system fastener features precise Class 2A thread fit tolerances with UNC coarse threads (10 threads per inch) ensuring proper engagement and interchangeability. Manufacturing complies with ASTM A193 specifications for high-temperature service, while the ASTM Grade B8M classification guarantees material consistency and performance. The right-hand thread direction and external hex drive conform to industry standards for compatibility with common installation tools. All dimensions including the 2 3/4" length, 1 3/4" thread length, and 1" grip length maintain strict manufacturing tolerances for reliable performance in critical applications.
