The disadvantages of the known design are the small contact area of the cross-head screwdriver with the slot, leading to a decrease in the maximum force when turning the head. The closest to the claimed technical solution is the "Screw head" CN 2786343 [2] hexagonal shape, equipped with a cross recess, with a short groove and an elongated straight groove perpendicular to the short groove along the entire upper surface of the fastener head, the side walls of the grooves are straight and parallel to each other , the width of the short and the length of the grooves are equal. The known design has a larger area of contact between the tool and the spline part of the fastening element in comparison with [1]. The disadvantage of the known design is the reduced reliability of the fastening due to a decrease in the torque due to the reduced contact area of the tool with the spline. Also, the disadvantage is a decrease in the durability of the tool, due to an increase in the specific pressure in the area of the contact patch of the tool and the slot.
Устройство действует следующим образом: головка крепежного элемента ограничена шестигранником 1. В центре головки пересекаются короткая 2 и длинная 3 канавки. Между короткими и длинными канавками расположены выемки 4 для малого гребня инструмента, соответствующие Тип Z по (ГОСТ 10753-86 Шлицы крестообразные для винтов и шурупов. Размеры и методы контроля).The device operates as follows: the head of the fastener is limited by a hexagon 1. In the center of the head, the short 2 and long 3 grooves intersect.

Технический результат достигается тем, что головка крепежного элемента шестигранной формы, снабженная крестообразным шлицем, с короткой канавкой и перпендикулярной короткой канавке удлиненной (сквозной) прямой канавкой вдоль всей верхней поверхности головки крепежного элемента (от края до края), боковые стенки канавок прямые и параллельны друг другу, ширина (расстояние между стенками) короткой и длиной канавок равны, отличающийся тем, что в центральной части шлица расположены выемки в соответствии с (одним из) типоразмером малого гребня тип Z стандарта ГОСТ 10573-86, ширина короткой канавки соответствует указанному стандарту, а ширина удлиненной канавки равна ширине короткой канавки.The technical result is achieved in that the head of the fastening element is hexagonal, equipped with a cross recess, with a short groove and an elongated (through) straight groove perpendicular to the short groove along the entire upper surface of the fastener head (from edge to edge), the side walls of the grooves are straight and parallel to each other. other, the width (distance between the walls) of the short and the length of the grooves are equal, characterized in that in the central part of the groove there are grooves in accordance with (one of) the size of the small ridge type Z of the GOST 10573-86 standard, the width of the short groove corresponds to the specified standard, and the width of the elongated groove is equal to the width of the short groove.
Технический результат – повышение надежности крепления достигается тем, что благодаря применению малого гребня и соответствию ширины канавок стандарту возрастает максимальный вращающий момент при закручивании крепежного элемента стандартной отверткой. Повышение долговечности достигается увеличением суммарной площади контакта инструмента – отвертки стандарта малого гребня тип Z стандарта ГОСТ 10573-86 и снижением удельного давления инструмента на шлиц, приводящее к уменьшению износа инструмента и головки крепежного элемента.EFFECT: increased reliability of fastening is achieved by the fact that due to the use of a small ridge and compliance with the width of the grooves to the standard, the maximum torque increases when tightening the fastening element with a standard screwdriver. The increase in durability is achieved by increasing the total contact area of the tool - a screwdriver of a small ridge type Z standard GOST 10573-86 and a decrease in the specific pressure of the tool on the spline, which leads to a decrease in the wear of the tool and the head of the fastener.
