A hexagon socket head bolt with a countersunk head, also known as a countersunk cap or countersunk cap bolt. In addition to general tightening of machinery, vehicles, architecture, etc., they are increasingly being used for large equipment such as heavy door hinges that cannot be supported by cross-recessed or slotted countersunk screws, and for parts that need to be firmly fastened. Although counterbore processing is required, after fastening, the surface of the mating material and the bolt head are flush, resulting in a visually beautiful finish, so its use is increasing in places where design is required, such as on furniture surfaces. I am. Generally available hexagonal wrenches cannot turn bolts, and there are also products with tamper-proof features that do not have a protrusion to grab the screws after tightening, and products with seals that are used for underwater machinery, transportation equipment, air conditioning equipment, and hydraulic systems. The size of the hexagon socket is smaller than a normal hexagon socket bolt (cap bolt). There are various standards depending on the manufacturer, and the full thread/half thread classification, thread length, etc. may differ depending on the manufacturer.
