Center Bolts

A term that generally refers to the bolt fitted in the leaf-spring assembly.

Center bolts is the most important part in a leaf spring assembly. At the center of each leaf is a hole. The center bolt head connects to the axle, which gives the truck its rear suspension in combination with the leaf springs.

Leaf spring is made up of number of spring steel leaves stacked one by one on top of each other and bolted together. It is attached to the rear axle and chassis of a heavy duty vehicle such as SUV, truck, van hence preventing the axle from snapping in from the jerks and shocks any vehicle may encounter.

Since this bolt has to withstand jerk loads it undergoes lot of tensile load. We ensure that these bolts are made of high quality alloy steel followed by proper heat treatment procedure so that the final product can withstand high tensile load at the same time not being too brittle. This property of center bolt makes it useful in automobile sector .We makes sure that bolts are made to internationally acceptable standards. Sizes of the bolts are available in diameters from 10mm to 27mm and lengths up to 400 mm. These are also available in short; standard and long head. These can also be made to customers special requirements.
