The RotaBolt® range provides you with either finger-tip, visual or remote measurement of tension throughout the life of the bolted joint. They surpass traditional tightening methods such as:
- Hydraulic Tensioners
- Flogging
- Torque Systems
which have severe control limitations and can result in unpredictable bolt tension and joint failure.
RotaBolts are setting new safety standards in a wide variety of sectors where joints are subject to fatigue, vibration, pressure containment and structural slippage.

The STS stud bolt tensioner range is designed for topside operation in a wide variety of applications including pipeline flanges, heat exchangers, pressure vessels, compressor covers, boiler feed pumps, anchor bolts and many others. The range comprises of 23 imperial and 29 metric models, all suitable for working pressures up to 1500 Bar. Imperial models cover all standard bolt sizes from ¾" to 4", metric versions (detailed on page 93) are available for bolt sizes from M16 to M100. Each of the hydraulic cylinders can be used with a variety of interchangeable nut rotating sockets and threaded pullers, available as individual parts or as convenient conversion kits (see pages 94 and 95 for more specific details). This will ensure that the maximum number of bolt diameters can be accommodated using the minimum number of cylinders. All Hi-Force hydraulic stud bolt tensioners are designed and manufactured to include a wear coated piston, maximum piston stroke indicator, self-energising high pressure seals, dual quick connect couplings for easy multiple tensioner connection and a user friendly operation and maintenance procedure. Additional or spare bridges, threaded pullers and nut rotating sockets can be supplied as and when required.

Features and Benefits:
Bolttech is known for solving the toughest bolting problems found in the industrial world today. These basic practices go into every design and manufacturing detail of our stud tensioning line of tools. We design our tensioners with quality, simplicity and versatility of the specific application and user in mind. Bolttech's Delta Series bolt tensioners maximize efficiency and minimize size for specific single stud size applications.
- Patented high pressure/low friction seals are designed to outlast the competition and provide accuracy within .5% with a calibrated pumping unit.
- Environmentally friendly, using water-filled tensioning systems.
- The direct axial load is applied to the bolt and inaccuracies created through friction are alleviated.

Tensioners
Signode hand tensioners allow operators to bring strap to desired tension with minimal interruption, effort and strap waste.
Most tensioners have a base which goes under the strapping and rests on the flat surface of the object being strapped. For smaller or irregular bundles, a push-type tensioner, which has no base under the strap, is recommended.
Feedwheel Tensioners
The feedwheel tensioner has a serrated feedwheel which engages the strapping firmly. There is no limit to the amount of slack it can pull out of the strap. Fast and easy to use, it requires the use of painted and waxed strapping.

HSK/SK Tool Clamping Systems for automatic tool clamping - Positive Taper Lock System for manual and automatic tool clamping
Increase of efficiency, reduction of cost and change to "lean production", however, optimizing quality at the same time.
So the today's requirements of the modern manufacturing. In order to carry for this development calculation, the positive taper lock was developed and tested in co-operation between the industry and the tool laboratory of the TH Aachen.
The positive taper lock connects the machine spindle as interface with the tool. The special requirements of a modern tool change system are:
- Particularly high changing accuracy and repeatability
- Safe transmission of high torques with a defined, radial location
- High static and dynamic flexural strength
- Particular suitability for high-speed operations in milling, drilling and turning machines
- Decrease of weight and building length opposite SK tools
- Simple handling
