Our trained technicians have proven track records in safety, quality and production.. 

Hydraulic Torquing 

Hydraulic torquing is stretching the stud or bolt to a predetermined load. The load is accomplished by turning the nut attached to the bolt which places the load on the stud/bolt.

+ Less accurate than hydraulic tensioning
+ More versatile
+ Simple to use

Stud Tensioning 

Stud Tensioning also stretch’s the stud or bolt to a predetermined load by using a hydraulic cylinder. The pulling force created by the cylinder stretches the stud/bolt then the nut can be tightened with little effort. The cylinder is then removed.

+ Stability and ease of control
+ Highly accurate
+ Most often used on large bolts

Applications for Controlled Bolting

+ Tightening nuts on equipment
+ Fastening pumps to bases
+ Connecting flanges
