The 5/16 in. x 3 in. Grade 5 Hex Bolt (Model 7200093) is a high‑strength fastening solution designed for applications requiring extended reach combined with increased tensile performance. Manufactured to Grade 5 specifications, this hex bolt offers greater strength and durability than standard low‑carbon bolts, making it well suited for moderate‑ to high‑stress assemblies in construction, industrial, automotive, and equipment applications.
This fastener features a traditional six‑sided hex head for secure installation using standard wrenches or sockets. The 3‑inch length provides added versatility for thicker material stacks, spaced components, and assemblies where deeper thread engagement is required to ensure long‑term joint integrity and resistance to loosening.
Packaged in a 100‑count box, this product is ideal for contractors, maintenance departments, fabrication shops, and equipment manufacturers who need reliable, professional‑grade fasteners in bulk quantities to support ongoing projects and operations.
