Technical Features
- Grade 8 construction: Meets the highest common SAE bolt grade classification, providing superior tensile strength compared to Grade 2 and Grade 5 fasteners — suitable for demanding structural and mechanical assemblies.
- Hexagonal head design: Engineered for wrench engagement, allowing high-torque installation and removal with standard open-end, box-end, or socket wrenches.
- 5/16-18 National Coarse (NC) thread: Coarse thread pitch offers faster thread engagement and greater resistance to cross-threading, making installation efficient in field and production environments.
- 1-inch nominal length: Provides a compact fastener profile suitable for applications with limited material depth or specific grip-length requirements.
Applications
- Structural metal fabrication requiring high-strength, wrench-driven fasteners
- Automotive and equipment assembly where Grade 8 tensile ratings are specified
- General mechanical assemblies utilizing 5/16-18 NC threaded components
- Replacement or repair applications calling for a hard-to-find coarse-thread hex cap screw in this specific size
