Fastener Tips

June 3,2010

When purchasing hex head bolts, you'll need the following information: 

     Diameter

     Thread pitch

     Length

     Grade of material

     Type of material

     Plating, if any. 

For instance, to purchase a Grade 8 Hex Head Bolt, it is best to use a

bolt gauge, something like the SORCG1, to get the correct diameter.

The gauge has limitations to sizes from a #6 diameter screw to 1” bolts.

To get the thread pitch, gauges like the HAN12016 can help.

To get the length, which for hex-head bolts is measured under the head

to the end of the bolt, use the SORCG1 gauge or a ruler if available. 

Our customer service people can help you identify the Grade of

your bolt and other specifications if needed.
