2. Applications:
Coarse Thread / Grade 18.8 / Phillips Drive / Flat Head. Stainless steel flat head machine screws have a flat top surface with a cone shaped bearing surface which is countersunk. This type of countersunk head leaves a flat surface once the screw has been driven in completely. Machine screws are most often used with a nut as a means of tightening unless they have a pre-threaded hole with the exact thread pitch. These screws are most commonly offered in smaller sizes. Other types of machine screws are: phillips flat head machine screws, phillips round head machine screws and stainless steel round head machine screws. Phillips head machine screws are the most recommended type of drive. A phillips drive offers more control and less slippage.
Fasten with a screwdriver to reduce the risk of over-tightening to protect the screw and fastened material
