Uxcell M4x24mm Fully Thread Round Head Machine Screws Bolts Fasteners (50-pack)

This item is designed with round head and metal material. Round head fasteners have a dome-shaped head. It is typically used when replacing existing round-head fasteners where an exact match is desired. Phillips drive style was originally designed so that the driver would slip out under extreme torque preventing over-tightening and to the fastener or the material. If nuts are needed use with nuts of the same threading for proper fit.
