Steel Coach Bolt, 1/4in x 1in

Introducing the range of RS PRO Lag 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 is available with a zinc or galvanised coating, making them much more cost-effective than their stainless-steel counterparts, while still offering a high level of protection against surface rust and oxidisation.

Lag screws or 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. They are able to carry intense loads and often also use a nut for additional strength and security when holding materials together. Lag bolts are most commonly used for:

• Carpentry construction like decking, railings and small frames


• Timber construction to support timber framing for houses


• Mounting heavy items onto walls


• Building work and construction

There is no difference between the two and they both do the same job. The name is interchangeable, but they are the same fastener.

RS PRO is our own brand range and brings you a wide range of high-quality, great value products offering you more choice. Trusted by engineers all over the world, every part of every RS PRO product has been rigorously tested against demanding industry standards - they’re only given the RS PRO seal of approval if we’re confident of their exceptional quality, which means you can be confident too.
