  • A Hexagon Bolt is a threaded fastener with a hexagonal head shape, and are designed to be installed using a spanner. Hexagon bolts are favoured for their robust shape, which makes them suitable for more heavy-duty fastening applications. Hexagon bolts are also generally available in larger sizes than alternative fasteners.
  • As their name suggests, Full Thread Hexagon Bolts are fully threaded. This type of bolt is required when the shaft of a fastener is being inserted completely into a threaded hole. Fully Threaded Bolts are often used to securely fasten two threaded sections together.

Selection Criteria

Entry-level zinc-plated sets are affordable for light tasks. Mid-range stainless steel kits offer the best balance of price and durability. Premium marine-grade options cost more but are essential for harsh environments.

Frequently Asked Questions

AI
304 stainless steel offers good corrosion resistance for general indoor and mild outdoor use. 316 stainless steel contains molybdenum, providing superior resistance to saltwater and harsh chemical environments, making it ideal for marine applications.
Lock washers provide friction to prevent loosening under vibration but can damage surfaces over time. Nylon lock nuts offer more consistent resistance to vibration without marring the bolt threads, making them preferable for repeated assembly and disassembly.
Measure the total thickness of the materials you are joining. Add the thickness of the nut and washer. The bolt length should exceed this sum by approximately one to two thread pitches to ensure proper engagement without bottoming out.
