Kerk has a wide variety of standard nut designs which offer many features to choose from. Once an application's most important requirements are understood, it becomes a matter of choosing the nut which best meets those requirements. Occassionally, more than one nut might do the job, but in the vast majority of situations, one nut design will stand above the rest. The matrix below may help to narrow down the choices before more specific data on this web site is studied.

All of Kerk's nuts can be modified to some degree to help them better meet specific requirements. Kerk is also very willing to discuss custom nut designs where requirements and volumes justify.
