■Hex Socket Countersunk Head Bolt -JIS B 1194-
The countersunk head profile allows use in applications where protruding fastener heads are undesirable. These provide greater clamping force than slotted bolts.
Additionally, as with hex socket button head bolts, the hex socket size is smaller than that of standard hex socket head cap screws. They are also known as countersunk cap screws. <Features> This is a bolt with a hexagonal socket in a countersunk head. Tightening is performed using a hex key (Allen wrench). Although classified as a bolt, they are most commonly used without a mating nut. They are also referred to as cap screws or socket screws. Unlike open-end spanners or wrenches used to tighten hex bolts, which require clearance space around the fastener, a hex key requires no such surrounding clearance. This makes hex socket head cap screws ideal for work in confined spaces and enables machine miniaturization. Their appearance has also led to increasing use in design-conscious applications.<Applications> These fasteners offer advantages such as space-saving machine miniaturization and high clamping force, and are widely used across many industries. They are particularly common in machinery and electrical components.
