Machine Screws - Cheese - BA

A machine screw is a type of screw that is commonly used in industrial and manufacturing applications to secure components within engines, electronic products and general machinery.

Cheese head machine screws have large, chunky, cylindrical heads where the height of the head is usually approximately half of its diameter. With a slotted head for installation with a flat-bladed screwdriver or bit, cheese head machine screws are strong and durable.

For a similar type of machine screw that has a slightly larger diameter flat head and a slightly lower thinner profile then choose our pan slotted machine screw.
