CSK BOLT

CSK bolts are flat headed bolts with hex socket drive into the head. These have a cone type neck and a flat head. Countersunk bolts are required to attain a smooth surface. Common applications that involve the use of CSK bolts include bridge decking, walkways, and railing. SEF manufacture and supply a broad range of CSK bolts. Our bolts are made of superior quality raw material. We design CSK bolts depending on the client’s specific requirements. Our bolts are best known for high tensile strength, wear and tear sensitivity, dimensional accuracy, and many unique attributes.

We have CSK bolts available with and without head slot. Special tooling can be created to produce a nonstandard head. Most commonly railway, wind tower, automotive, nuclear power, construction, and electronic industry needs CSK bolts.
There are two main reasons to use CSK bolts:

• To create a smooth finish on an object without bolt heads sticking out.
• To prevent the exposure of sharp edges.
