ROD BOLT

We are the Roll-Fast manufacture of rod bolts from M10 to M 100 or 1/2” to 4” diameters. Specially we manufacture these bolts for ship engine assembly.

What is use of Rod Bolts?

A connecting rod is the part of a piston engine which connects the piston to the crankshaft . Together with the crank, the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft. The Rod bolts is used for assembled the crank pin end to I beam of connecting rod. This is most important fasteners in any engine, as they hold the key to the entire rotating assembly.

Roll-Fast have in-house facility of Hot forging with Higher precision CNC Machining. We have heat treatment furnace from Dowa hightemp Japan that gives higher hardness & strength on these bolts. We provide 90% core hardens. Also, we provide different coating on these bolts like Geomat, Zinc flake, black etc.

Custom Rod Bolts

Roll-fast is specialization in custom bolts manufacturing. We have CAD team which create 3D model of your bolts and make is it feasible in every different kind of situation with help of simulation & Finite element analysis (FEA) Tools. We check your bolt in different load & jerk pressure parameter.

As size you want just share with us and we can make it possible.
