Description of Cross Countersunk Head Machine Screws
Cross recessed countersunk head machine screws are those with a flat head and countersunk head. Countersunk head machine screws can also be called flat head machine screws, countersunk head screws, half countersunk head screws, half countersunk head screws. Generally countersunk head screws are cross recessed and can be divided into blue and white zinc countersunk head machine screws and color zinc countersunk head machine screws depending on the surface treatment.
Precautions for using cross countersunk head machine screws.
1、The reaming taper should be 90°, to give assurance, rather than less than 90°, but not more than 90°this is a key trick.
2、If the sheet metal thickness is less than the thickness of the countersunk head screw, you can change the small number of screws, or rather expand the hole smaller than the diameter of the bottom hole can not be expanded so that the parts can not be pressed tight.
3, parts such as more than one countersunk head screw hole, processing to be more precise, once the drilling is distorted, assembly is very ugly, but as long as the error is not large is completely tightened, because in tightening, if the screw diameter is not very large (about not more than 8mm), the hole distance error, the screw head will be tightened due to the force and deformation or will be unscrewed.

Production Process
Application of Cross Countersunk Head Machine Screws
Cross recessed countersunk head screws are commonly used in electrical equipment, electronic machinery, mechanical equipment, household appliances, digital products, water conservancy projects, renovation and construction, etc. Countersunk head screws are generally made of metal screw wire pier, formed in rolling teeth, cylindrical, with a flat head, such as an inclined surface around the side of the screw, so that the screw can be locked tightly to the screw cap or other objects. The top of the countersunk head screw is larger in diameter and can be round or hexagonal, allowing tools such as screwdrivers or wrenches to turn the screw. The protruding top also prevents the screw from drilling too deeply through the material and increases the pressure of the screw on the material. Countersunk head screws can usually be removed or reinserted at will without loss of efficiency and provide more force than nails and can be used repeatedly. Countersunk head screws are used on top of the product material, the head can be fully sunk, the head of the screw will not play a role in obstruction.
