Galvanized Cross Recessed Countersunk Flat Head Machine Screw
Machine screws are straight shank fasteners with a blunt end and machine threads that run the entire length of the shank. They are designed to go through a hole or machine screw nut that is pre-tapped to form a mating thread for the screw. Machine screws are often described as a small diameter bolt because of their blunt end, and some styles are called stove bolts. Machine screw heads come in binding undercut, button, fillister, flat, indented hex, indented hex washer, oval, pan, round, and truss. You can read more on each style below. Machine Screw drive styles come in hex slotted/unslotted, one way tamper proof, phillips, phillips pin head, phillips/slotted combo, six-love, slotted, spanner tamper proof, and triangular slotted
