What is a Machine Screw?
Amachine screwis a fastening device similar to a bolt but having a pozidrive or slotted head which allows it to be turned with a screwdriver. It is usually applied to fastening metal components together that are pre threaded and not expected to withstand a heavy load/ force.
How do you measure a countersunk fixing or fastener?
Fixing and fastener length refers to the length of the material which contacts the joining materials/ parts. So, as a countersunk head sits below the surface of the joining materials/ parts, the length is from end to end.
