What are Imperial Coach Screws?

Imperial coach screws, identified by their hexagonal head, are high-torque engineering components that form a crucial part of precision assemblies. Unlike imperial carriage bolts, coach screws rely on their deep self-tapping threads to provide a firm anchorage through the utilisation of tools such as socket sets or spanners. This inherent feature makes them a key component in structural applications, fastening metal to wood or to heavy-duty synthetic materials, where high-load capacity and resistance against loosening are paramount.

How Imperial Coach Screws Work.

The unique functional prowess of imperial coach screws lies in their design. The hexagonal head, a characteristic trait of these fasteners, allows a high degree of torque application. As the torque is increased, the clamping force between the connected materials elevates, resulting in a more secure joint. The self-tapping threaded section, engaging with a mating pilot hole, ensures a firm connection. This combination of high torque and secure clamping makes imperial coach screws an engineer's go-to choice for heavy-duty applications that demand superior connection strength combining metal and other materials.

What Material Are Imperial Coach Screws Made From?.

Imperial coach screws at Accu are crafted from A2 Stainless Steel, a material known for its excellent corrosion resistance and mechanical properties. This grade of stainless steel endows these screws with an impressive load-bearing capacity and durability, even in environments exposed to moisture and other corrosive elements.

To cater to specific application needs, Accu provides an additional AccuBlack finish. This matte black coating not only enhances the screw's aesthetic appearance but also adds an extra layer of corrosion resistance.

What Size and Type Imperial Coach Screws Are Available?.

Accu stocks imperial coach screws in a spectrum of sizes, ranging from a thread size of 1/4" for smaller applications to a hefty 3/4" for tasks demanding larger load capacities. Our lengths range between 2" and 16" providing coverage for many engineering projects.


Q: What advantages do imperial coach screws offer over other bolt types?.

A: Imperial coach screws, due to their hexagonal head design, allow a higher degree of torque application. This makes them ideal for structural applications where a secure, high-load-capacity connection is essential. They are also primarily designed to be driven into wood or other synthetic materials.

Q: Are imperial coach screws suitable for corrosion-prone environments?.

A: Absolutely. Our imperial coach screws are manufactured from A2 Stainless Steel, renowned for its corrosion resistance.

Q: What tools are suitable for the installation of imperial coach screws?.

A: Imperial coach screws can be installed using a socket set or spanner, thanks to their hexagonal head design. This ensures a higher torque application and a firm connection.

Q: How can I select the appropriate size of imperial coach screws for my project?.

A: The selection of the bolt size depends on the requirements of your project, including the thickness of the materials, the load-bearing capacity required, and the dimensions of the pre-drilled holes.

Q: Does Accu enforce a minimum order quantity for imperial coach screws?.

A: At Accu, we cater to a wide range of project needs. Whether you require a single bolt or a bulk order of thousands, we are able to accommodate your requests without a minimum order quantity.
