Cross Hex Head Self Tapping Screw
The specifications of cross hexagonal self tapping screws are mainly based on the national standard GB/T 9456-1988, and their thread specifications cover various models such as ST3.5 and ST4.2. The nominal length range is from 6.5mm to 50mm, and the surface treatment usually adopts galvanizing passivation process.
This type of screw adopts a hexagonal head design, with a cross
shaped groove (H-shaped) at the center of the head for efficient
installation using a screwdriver.
Its self tapping performance allows the screw to directly cut wood
or thin metal during the screwing process, without the need for pre
drilling, significantly improving installation efficiency.
Some models (such as the C-type) also incorporate a concave
structure, further enhancing the stability of the bite between the
head and the tool
Cross hexagon head self tapping screws are widely used in furniture
manufacturing, woodworking, and construction decoration fields,
such as fixing wooden floors, wooden brackets, or decorative
materials.
In addition to the national standard GB/T 9456, there are also
industry standards such as SJ 2826-1987, which are applicable to
specific scenarios such as the electronics industry.
In international standards, American and Japanese standards also
define similar types of hexagonal self tapping screws, such as Type
B/C thread forming specifications, to meet the product needs of
different countries
