Imperial Grub Screws | Imperial Set Screws

Grub Screws, also known as set screws, are small, headless, fully threaded screws with either an internal hex drive or slot at one end and either a cup, cone, flat or dog point at the other end. Generally used to secure assemblies in a neat, discreet manner where a traditional nut and bolt would be too cumbersome. Found in a huge variety of common assemblies from door handles to carburettors. Though difficult to source in the UK and Europe, our range of imperial grub screws includes UNC and UNF thread forms.
