Key Features & Benefits at a Glance
- Exceptional corrosion resistance thanks to 18-8 Stainless Steel construction, ideal for harsh industrial environments.
- Superior mechanical strength with 75,000 psi tensile strength and Rockwell B96 hardness for reliable performance under high stress.
- Easy installation and removal with an external hex drive and standard UNC coarse thread design, reducing assembly time.
- Consistent thread engagement ensured by Class 2A thread fit, providing predictable clamping force and vibration resistance.
- Full thread coverage along the 2" length maximizes grip and load distribution in thick materials.
- Heavy-duty compliance meeting ASTM A193 Grade B8 specifications for high-temperature and pressure applications.
- Broad compatibility with inch-system tools and components, simplifying procurement and maintenance.
Professional Applications & Engineering Value
Engineered for demanding settings, these 7/8"-9 UNC hex head screws in 18-8 Stainless Steel address critical challenges like corrosion, thermal stress, and mechanical fatigue. The coarse thread and fully threaded design enhance holding power in soft or composite materials, reducing the risk of stripping. With ASTM A193 Grade B8 compliance, they are trusted in industrial fasteners for pipelines, pressure vessels, and structural assemblies, where consistent tensile strength and durability are non-negotiable. The external hex drive allows for high-torque application, ensuring secure connections in heavy-duty machinery and equipment.
Specification Summary & Compliance
This fastener adheres to precise dimensional standards, including UNC thread with Class 2A thread fit for reliable interchangeability. It meets ASTM A193 specifications for material and performance, ensuring compliance with industrial safety norms. The inch system measurements (e.g., 2" length, 7/8"-9 thread size) support global engineering consistency, while the 18-8 Stainless Steel composition aligns with RoHS and REACH directives for environmental safety.
