GOST 1146-80 Semi-countersunk head screw with straight slot

     GOST 1146-80 is a standard that defines the parameters and characteristics of semi-countersunk head and straight slot screws. Semi-countersunk head and straight slot screws have a head that is partially immersed in the material when tightened, which provides a smooth external surface profile. The straight slot is formed at the end of the screw, which allows you to use a conventional screwdriver to tighten it. Semi-countersunk head and straight slot screws are commonly used in the woodworking industry to connect wooden parts and fasten wooden structures. In general, countersunk head and straight slot screws are important elements for joining wooden parts and fastening wooden structures. They ensure a reliable connection and ease of maintenance and repair.
