TAC-TOP HYDRAULIC TOOLS
TAC-TOP Hydraulic Bolt Tensioners
Hydraulic Bolt Tensioners, utilizing pure tension to elongate the bolt directly without twisting or applying lateral shear force, one of the best ways of tightening bolts.
Self-excited sealing (SES) to ensure no leakage
Sealing of the Tensioner is the key to its quality. The TAC-TOP tensioner uses the exclusively patented self-excited sealing and special materials to attach itself onto the hydraulic cylinder firmly. The higher the pressure is, the stronger the attaching force becomes. Even if the hydraulic cylinder exceeded its intended service life, the sealing would not be aging off.
Each seal is precisely made. The precise machining and unique material make it match perfectly with the hydraulic cylinder. Not only does it guarantee high-quality sealing, but also ensures a small friction of coefficient so that the hydraulic cylinder is easy to return after being pulled-up.
Safe and Reliable
Over stroke indicator (the red line) warns that the maximum stroke is reached. If the maximum stroke is exceeded, an internal depressurizing system will start automatically to release pressure and to avoid accident.
Strict Quality Control
Ultra high pressure circulating detection ensures the quality of products. Ultrasonic testing accurately calibrates the tensile force acting on the bolt.
1. Spring Retract Tensioner Series
- With advanced manufacturing equipment and innovative computer design, the TAC-TOP hydraulic auto-retract bolt tensioner overcomes the common retract problem of bolt tensioner

TAC-TOP Hydraulic Torque Wrench
1. Tac-top Square Drive Wrench
High torque, light weight, safe to use.
- Made of aircraft aluminium alloy TITAL399, high strength, high ductility, and light weight.
- Integrated body frame enables high safety and long service life.
Technology innovation, easy to operate.
- 360°×180° swivel design enables the hose to move easy. Reaction arm trigger design, allows 360° fine tuning, which is easy to find support and operate.
- disengagement lever make it easy to remove the wrench from the application.
2. Tac-top Low Pro Hex Wrench
Low profile wrenches, include a power part and a link. Each power part can be selected with different specifications of hexagonal or octagon link.
Swivel design enables the hose to move easy. Reaction arm supplies great support in adjacent position. The link is aligned with the power part, so that the power part is unstressed, which ensures the long service life of the tool.
