FAQS on 5 8 x 12 galvanized carriage bolts

Q: What are the dimensions of 5/8 x 12 galvanized carriage bolts?

A: A 5/8 x 12 galvanized carriage bolt has a 5/8-inch diameter shank and a 12-inch length. The "galvanized" coating provides rust resistance. These bolts are ideal for heavy-duty outdoor applications.

Q: How does a 3/8 x 3.5 galvanized carriage bolt differ from standard bolts?

A: The 3/8 x 3.5 galvanized carriage bolt features a 3/8-inch diameter and 3.5-inch length, with a square neck to prevent spinning during installation. Its galvanized finish adds durability against moisture, making it suitable for fencing or deck projects.

Q: Can 3/8-inch galvanized carriage bolts be used in marine environments?

A: While 3/8-inch galvanized carriage bolts resist rust better than non-coated bolts, they are not fully corrosion-proof in saltwater. For marine use, stainless steel or hot-dip galvanized variants are recommended for extended longevity.

Q: What applications suit 3/8 x 12 galvanized carriage bolts?

A: 3/8 x 12 galvanized carriage bolts are ideal for structural connections requiring longer threading, such as securing timber beams or metal brackets. The zinc coating protects against weathering in outdoor settings like pergolas or farm equipment.

Q: Are 3/8 x 3.5 and 3/8 x 12 galvanized carriage bolts interchangeable?

A: No – the 3.5-inch and 12-inch lengths serve different purposes. Shorter 3.5-inch bolts work for lightweight materials, while 12-inch versions provide deeper penetration for thicker assemblies. Always match bolt length to your project’s material thickness.
