What is the difference between machine screws and bolts?

Machine screws have a slotted head, whereas bolts have a hex head.To install a machine screw, place a flat-heat or Philips head screwdriver into the slotted head and turn it. The screw can be removed by turning the screwdriver in the opposite direction (anti-clockwise).Bolts feature a hex head instead of a slotted head. For installing a bolt, place a hex socket over the head and turn it.Machine screws are generally smaller than bolts. Machine screws are less than 1 inch long, whereas bolts come in a variety of sizes, with some of them being over 2 inches long.

What standards do these machine screws comply with?

These machine screws adhere to AN, ASME, ASTM, CSA, DIN, EHEDG, FDA, Federal Specifications, IFI, ISO, JIS, Military Specifications, MS90728-10, NAS, SAE and UL standards.
