ASME B18.3 specifies the imperial series of socket head cap screws, driven by an internal hexagon socket, making it the correct fitting for UNC and UNF threaded assemblies. The internal hex socket allows high torque to be applied with a short key in confined spaces. Imperial threads are not interchangeable with metric, so this size suits equipment originally built to UNC or UNF.\u003c\/p\u003e\u003ch3\u003eTypical applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMaintenance of imperial-threaded plant and machinery\u003c\/li\u003e\n\u003cli\u003eAmerican and legacy British equipment repair\u003c\/li\u003e\n\u003cli\u003eCounterbored joints in imperial assemblies\u003c\/li\u003e\n\u003cli\u003eTooling and fixtures built to imperial standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAvailable in packs of 10 to 50, with free next-day UK delivery on orders over £50 and 30-day no-quibble returns.
