CSK Socket Bolt

Also known as a flat-head screw, a countersunk screw is a type of screw that's designed to rest flush with the object or surface in which it's inserted. They are called “countersunk screws” because they “sink” into objects and surfaces. They feature a flat head that tapers along the shaft.

CSK socket bolts, also known as flat-head screws, are designed to rest flush with the surface they are inserted into, providing a sleek and unobtrusive finish. These countersunk screws feature a flat head that tapers along the shaft, allowing them to "sink" seamlessly into objects and surfaces. 
Ideal for applications where a smooth, level surface is required, Pankaj International offers high-quality CSK socket bolts that ensure reliable and aesthetically pleasing results. As a leading fasteners manufacturer in Ludhiana, we provide a comprehensive range of high tensile bolts, nuts, screws, and washers.
