Skidmore Wilhelm Model K Bolt Tester

The Skidmore Wilhelm Model K is our largest unit! This unit is designed for very large bolts (1 ½" to 2 ½" and 36MM to 64MM) This unit is used most often on Windmill Projects and very large structures.

The main considerations when choosing the proper calibrator are first, the size of the bolt in diametre and length that you will be testing, and second, the type of bolt head (standard, heavy, hex or tension control) You will need to purchase a plate for each diametre of bolt you will be testing and a bushing for each diametre and each type.
