3/8 in. x 2‑1/2 in. Grade 5 Hex Bolt – 50 Count (Model 7200141)

The 3/8 in. x 2‑1/2 in. Grade 5 Hex Bolt is engineered for applications requiring superior strength, torque capability, and long‑term durability. Made from heat‑treated medium‑carbon steel, this bolt delivers significantly higher tensile and yield strength compared to standard Grade 2 hardware, making it an ideal choice for automotive work, agricultural equipment, industrial machinery, construction, and structural fastening.

A zinc‑plated finish protects the bolt from rust and corrosion, ensuring reliable service life in demanding conditions. The hex‑head design allows secure engagement with wrenches, sockets, or power drivers, providing consistent torque transfer and a dependable, tight fit. Coarse 3/8‑16 machine threads offer excellent holding power, vibration resistance, and ease of installation in tapped holes or when paired with compatible Grade 5 nuts and washers.

With its extended 2‑1/2 in. length, this fastener is especially well‑suited for deeper material connections, bracket installation, structural assemblies, and load‑bearing applications requiring added reach.
