  • What is a m8 bolt?

    The M8 will measure about 8 mm in diameter, more likely, just a touch undersize, (.31496") The M10, about 10 mm in diameter, (.3937") and the M12 about 12 mm in diameter, (.4724"). The "M" designates the bolt is Metric and the number after the M indicates the size. The number after that is the length.
  • What is m3 in screws?

    The M3 is a metric screw specifying a nominal diameter of 3 millimetres (0.12 in); and standard coarse thread pitch defined as 0.5 millimetres (0.020 in). The M3 is the second most common screw found in PCs. It commonly appears in many lengths from 1-20mm.

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.
  • How do you measure a metric bolt?

    Metric fasteners are specified with a thread pitch instead of a thread count. The thread pitch is the distance between threads expressed in millimeters (measured along the length of the fastener). For example a thread pitch of 1.5 means that the distance between one thread and the next is 1.5mm.
  • What is the tensile strength of a325 bolts?

    Grade A325 bolts are available in diameters from 1/2 to 1-1/2 inch (for diameters greater than 1-1/2, ASTM A449 specifications should be considered) with a minimum tensile strength of 120,000 PSI. They also come in two types.
C.

What does 8.8 mean on the head of a bolt?

If you have ever looked a metric hex bolt you might notice the markings 8.8, 10.9 or 12.9 this does not mean grade 8,10 or 12. The grade 8.8 refers to the tensile strength which is generally 116,000 psi, grade 10.9 is generally 150,000 and grade 12.9 is generally 175,000 psi.
  • What does class 10.9 bolt mean?

    Our metric grade 10.9 bolts meet ASTM A324 grade BD and SAE J429, grade 8 standards. The yield strength of the bolts is 940 and the tensile strength is 1040 MPa. U-Bolt-It is a leading distributor and manufacturer of high quality metric grade 10.9 bolts.
