Description

Mechanical Multi-Jackbolt Pretensioners (MJP) type PM10 are designed according to ISO and correspond to steel property class 10 for nuts on bolts 10.9 (specified up to M39 according to ISO). All dimensions are specified according to the same guidelines.

Mechanical Multi-Jackbolt Pretensioners (MJP) type PM10 are used for high strength bolting in all areas of industry. Due to the captive mounted Mammoth™ Jackbolts, PM10 are best suited for highly dynamic applications such as turbine runners.

The hexalobular head (Torx®) of the Jackbolts is extremely wear-resistant and safe to handle.

Applications

General mechanical engineering, shipbuilding, heavy mechanical engineering, power plants, chemical industry. Used on couplings, slewing bearings, presses, bolted split joints and many more » see Applications
