Boltight’s
standard range of hydraulic bolt tensioners
are designed for general use on top side applications. Each tool comprises of a hydraulic cylinder, bridge, puller and socket. Interchangeable adaptor kits fit common hydraulic cylinders to enable the tightening of multiple bolt sizes.Boltight solutions make it possible to tighten and loosen multiple bolts simultaneously using high-pressure hydraulics. Bolt tensioners stretch the bolt before the nut is wound down under zero friction, ensuring extreme accuracy, speed and uniformity.
SUBSEA TENSIONER
are specifically configured for Subsea applications. They feature a nickel-plated exterior that allows them to withstand high initial bolt stress. The tools are fitted with the Boltight composite material high pressure seals, which clip into place and require no adjustment.

TYPHOON TENSIONERS
range of bolt tensioners offer a high-load, low profile solution for space-restricted applications demanding high and accurate preloads, such as wind turbines. The tensioners exert a high load with both the multi-stage, ideal for radial obstruction applications and the single stage, for vertical obstruction applications.
TSR+ TENSIONERS
Fastest auto return tensioner on the market: With a focus on productivity and a reduction in downtime, the TSR+ auto return tensioner range has been designed to ensure fast, simple, safe and reliable operation.
Boltight
Xtra load range
has been developed for high loads and reduced dimensions. With 30% more load than typical standard ranges and a large usable piston stroke, it provides users with versatility and fast, accurate operations.
ENGINE TOOL SETS
are available for the installation and maintenance of gas and oil diesel engines. We stock sets for various OEM engines but can also custom design sets for any diesel or gas engine. All tool sets are supplied in a box with a pump, hoses and operating manual.
HYDRAULIC NUTS
enable large diameter bolts to be tensioned with ease to high and accurate preloads. A hydraulic pump activates the internal jacking system, so the effort required to tighten a very large diameter bolt is reduced to the effort needed to operate the pump. As there is no nut rotation during tightening, the operation can be performed in a confined space and torsional stresses on thread damage are eliminated. Any number of hydraulic nuts can be connected together for simultaneous operation, ensuring all bolts in the joint can be evenly loaded to the same high and accurate preload.
