Steel Coach Bolt, 5/16-18 x 1 3/4in

Introducing the range of RS PRO Carriage Bolts, a high quality and heavy-duty fastener solution for heavyweight applications such as connecting heavy lumber or other materials that are load bearing. Each fastener is made from steel and are available in variations with a zinc coating or galvanised, making them much more cost-effective than their stainless-steel counterparts, while still offering a high level of protection against surface rust and oxidisation.

Carriage bolts or coach bolts are some of the toughest and hardest working fasteners and are second to none when it comes to durability and load-bearing capacity across the applications they are used in, similar to Lag Bolts or Lag Screws. The shape of the bolt has been designed to be self-locking when placed through a hole offering additional strength and security when holding materials together. Carriage bolts are most commonly used in:

• Railroad industry


• Mining and farming


• Water conservation and treatment


• Building and construction
