How to use DIN965 Cross Recessed Countersunk Head Screw correctly?

Jiaxing Xinhan Technology Co., Ltd. is a hardware manufacturer specializing in the production of various high-quality fasteners, among which din965 cross recessed countersunk head screws are of high quality and low price.

The correct use of DIN965 cross recessed countersunk head screws mainly involves its application scenarios, usage methods and precautions.

Applicable scenarios: Cross countersunk head screws are suitable for occasions where nail heads are not allowed to be exposed, commonly found in machinery, electrical appliances and buildings. When using, it is necessary to make corresponding tapered countersunk holes on the surface of the parts so that the screws can sink without exposing.

How to use:

When the thickness of the part is greater than the thickness of the countersunk screw head, the screw can be fully screwed in without any threaded parts being exposed.

When the thickness of the part is less than the thickness of the countersunk screw head, it is common for sheet metal parts in mechanical equipment, such as the connection between the hinge of the chassis and the door and the box. In this case, due to the small thickness of the part, the screw via becomes a cone hole, and the bottom of the screw head root is squeezed with the top of the threaded hole. Although it feels that the screw is tightened, the sheet metal part is actually stuck rather than pressed. This may be because some workers use the drill bit to ream the hole at an incorrect angle, resulting in the countersunk screw not being tightened.
