Machine screws are uniformly threaded screws, meaning they maintain the exact same diameter throughout the entire length of the threaded section of the fastener, unlike wood or chipboard screws which have tapered threads.
Machine screws can be used to fasten components together by means of through holes and secured with a nut at the other end. But they can also be used to fasten components together by passing the machine screw through the parts and then threading it into the rearmost component.
As the name suggests, these screws can be used to fasten components in machines, tools, appliances and electronic devices.
The countersunk machine screw has a flat countersunk head for application where a flush finish is required.
Features a relatively tall, rounded, head with cylindrical sides as well as deep slots in the head to allow increased driving power.
