Работа предлагаемоГО болта осуществл етс  следуюшим образом. Крут щий момент с пера отвертки передаетс  па шлиц. В случае вертикального расположени  граней шлица и отвертки, вследствие наличи  допускаемого зазора между nepOiM отвертки и шлицом, контакт между НИми начинаетс  с периферийной части, что не позвол ет полностью использовать рабочую поверхность граней шлица. Дл  улучшени  контакта грани пазов шлица выполн ют наклонными. Это позвол ет сместить зону ко такта на большую глубину и увеличить предельный крут щий момент. Формула изобретени  Болт с потайной головкой, имеющий фигурный шлиц под ключ, в виде центральногоThe operation of the proposed bolt is carried out as follows. Torque from the screwdriver pen is transmitted to the slot. In the case of a vertical arrangement of the faces of the slot and a screwdriver, due to the allowable gap between the nepOiM screwdriver and the slot, the contact between the THEMI begins from the peripheral part, which does not allow to fully use the working surface of the faces of the slot. In order to improve the contact, the faces of the slots of the slot are inclined. This allows the zone to be shifted to a greater depth and to increase the limiting torque. The formula of the invention The countersunk head bolt, having a turnkey shaped vents, in the form of a central углублени  и трех пазов, расположенных под углом 120° в плане и содержащих грани на заворачивание и отворачивание, отличающ и и с   тем, что, с целью увеличени  момента на отворачивание, грань паза на заворачивание выполнена с уклоном 1,5-5° к центру головки болта ио радиусу, а грань на отворачивание выполнена с уклоно.м О-3° и смещена относительно грани на заворачива- ние на ширину паза.recesses and three grooves located at an angle of 120 ° in plan and containing faces for turning and turning away, which is also distinguished by the fact that, in order to increase the turning point, the edge of the turning groove is made with a slope of 1.5–5 ° to the center the head of the bolt has a radius, and the turning edge is made with inclinations O-3 ° and is shifted from the face to wrap by the groove width.
