B18.3 specifies a cylindrical head driven by an internal hexagon socket, making it suitable for counterbored holes and confined assemblies. The internal hex socket allows high torque to be applied with a short key in tight spaces, and the compact cylindrical head sits neatly in a counterbore where a hex head would foul adjacent parts.\u003c\/p\u003e\u003ch3\u003eTypical applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMachine tooling, jigs, and fixture assembly\u003c\/li\u003e\n\u003cli\u003eCounterbored joints where the head must sit flush or below the surface\u003c\/li\u003e\n\u003cli\u003ePrecision equipment and instrument housings\u003c\/li\u003e\n\u003cli\u003eGeneral engineering and maintenance fixings\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAvailable in packs of 10 to 50, with free next working day delivery on UK orders over £50 and 30-day returns.
