Frequently Asked Questions

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.
