Hex bolts are hexagonal headed fasteners that are available in various shapes and sizes. M6 Hex Bolt has a diameter of 6 mm. This is indicated by the M6 number mentioned in it. M6 Hex Bolt Dimensions vary in shape and size. They are made up of different materials depending on their use.
M6 Hex Socket Bolt also known as Allen bolt require a special key designed to unscrew or screw these bolts. This makes it difficult for anyone to tamper with these bolts and gives them a permanent seal. They cannot be easily removed the special key is a must to remove it.
Applications that require a bolt along with a washer to be attached for equal distribution of load M6 Hex Flange Bolt are used. The M6 Hex Bolt Head Dimensions have a wider base that eliminates the need for a washer thus distributing the load throughout the fastener.
An M6 Hex Cap Bolt has a symmetrical sloping edge on the surface of the washer-faced head. The wrench used to bolt these M6 Hex Bolt Head needs to correspond to the diameter of the hex head. We have M6 Hex Bolt Standard Lengths. We can also customize and change the lengths as per your requirements. The bolts that we provide can be used with a nut or a tapped hole. They display good corrosion resistance depending upon the material used in making them. They are used in the construction of bridges, docks, automobiles, highway structures, and engineering industries.
