Low Head socket head cap screws are high strength, precision fasteners that are designed to be used in applications where head height is a problem. Because of their reduced head height and smaller socket size, they cannot be preloaded as high as a standard socket head cap screw.
Slotted screw heads have a single horizontal indentation referred to as the slot. The fastener head is driven by a “common blade” or flat-bladed screwdriver. The slot has a flat bottom and are good for low torque low speed applications.
The flat-head screw is flush with the surface. Type basic types of screwdrivers are needed for driving the different types of screws. The regular slotted screw has a slot in the head, while the Phillips-head screw has a cross slot. Always use the proper screwdriver for the screw you are using.
