Standard Machine Screws

62 products

These screws join metal objects together through existing tapped holes and are typically used in high-volume automotive or machinery assembly and repair because of their uniformity. They are smaller than most screws. Machine screws are identified by threading that remains the same size from the top of the screw to the bottom.

Hex Head Machine Screws

Hex Head Machine Screws
Hex head machine screws allow for more high-torque tightening than other types of machine screws. They have six flat sides and a flat, indented hexagonal top. They are most commonly made in smaller sizes to be used in high-volume assembly applications. Hex heads may be slotted for tightening with a screwdriver or unslotted for tightening with a socket wrench. These screws can be used with nuts or in prethreaded holes with a matching thread pitch.
