16mm X 80mm GI Bolt

Material: galvanized iron (GI) for corrosion resistance. Size: 16 mm diameter, 80 mm length. Head type: hexagonal. Threads: threaded shaft for secure fastening. Designed for durability in extreme temperatures and pressure, suitable for outdoor and indoor use.

It’s intended for joining heavy‑duty materials such as wood, metal, and concrete. Depending on the application, you may pair it with a nut and washer to achieve a secure, clamped connection.

Align the hole or threaded insert, insert the bolt through the components, and tighten using a wrench that fits the hex head. If required, add a nut and washer on the opposite side and tighten to the desired clamping force.

You’ll typically need a wrench or spanner that fits the hex head. If using a nut on the opposite side, have a compatible wrench for that nut as well, plus any washers recommended for your joint.

Yes. The bolt is galvanized iron, which provides corrosion resistance for outdoor use and challenging environments, helping extend its service life.

If you’re choosing among GI bolts on Fepy, consider length and diameter for load and fit. For example: 12mm x 60mm GI Bolt offers a shorter option, 16mm x 100mm GI Bolt provides a longer fastening, and 10mm x 80mm GI Bolt offers a thinner profile. Each option is designed for different load and hole size requirements.

Common use cases include timber framing, machinery mounting, metal assemblies, fencing, and other heavy‑duty fastening tasks where a strong, corrosion‑resistant connection is required.

Keep the bolt clean and dry when possible. Periodically inspect for signs of corrosion or wear, and re-torque if necessary. If the joint will be exposed to outdoor elements, ensure seals or coatings are maintained to preserve the galvanization.

Check the hole diameter and depth in your components to ensure a snug fit, confirm that the threaded length engages enough threads for secure clamping, and verify the hex head clearance for your installation space. Matching with a nut and washer as needed helps ensure proper load distribution.

The bolt is eligible for return under Fepy’s standard return guidelines, subject to the conditions of unused/untouched product in original packaging and within the applicable return window.

Yes. Use appropriate PPE, avoid over‑tightening to prevent stripping threads or damaging components, ensure compatible nut/washer usage, and follow standard fastener installation practices to maintain joint integrity and safety.
