Our complementary services

Just in time (order picking)

Call us if you are in need of an urgent delivery. We hold a wide-ranging stock of both current and specialist fastening materials. And if the part you require is not in stock, we will either try to source it for you or modify existing components.


The modification of existing fastening materials may mean we need to cut them to the correct size. We also have the necessary tools to enable us to serve you with customised products.
