  • How do metric bolt sizes work?

    The size of a metric screw or bolt is specified as diameter, pitch and length, in millimeters (millimeters is abbreviated "mm"). For nuts, size will appear as diameter and pitch. In the example above, a pitch of 1.0 means that from one thread to the next thread, the distance is 1.0 millimeter.

  • What does m12 stand for?

    Those are metric screw dimensions. M10 means a 10 millimeter outer diameter for the bolt or whatever piece it is; M12 means 12 millimeters. The part after the 'x' is the pitch -- how many mm a thread is wide. To figure out which you have, you can measure the existing part with calipers and a thread gauge.

How do you measure the size of a bolt?

Diameter is in either Inches ( not decimal ) or Millimeter. Second measure the pitch Pitch is threads / per unit. Inches are measured threads per inches. Third measure length Length is measured from behind the head to end, ( except for flathead is measured total length ) .
  • What are the types of bolt?

    Wood Screw, Sheet Metal Screw, Hex Bolt, Lag Bolt, etc. Fasteners in some categories are available with different drive types such as Philips or Slotted. In other categories such as lag bolts there is either only one drive type or the drive type is implied to be of a standard type.
