Versatility in tightening large nuts 10 March 2017
  • Mechanical tensioning and hydraulic tensioning are common methods to tighten large size bolts, each with its own strong advantages. Superbolt multi-jackbolt tensioners have been on the market since 1984, enabling bolted joints to be tightened mechanically without specialised skills or heavy tooling. But what if there was a product that combines the strengths of both Superbolt mechanical tensioning and hydraulic tensioning into one?

    The new VersaTite™ Hydraulic Mechanical Tensioner from Nord-Lock Group combines the speed and uniformity of hydraulic tensioners with the accuracy of Superbolt mechanical tensioners.
    Superbolt VersaTite gives versatility in multiple ways, including: VersaTite products can be hydraulically pressurised to achieve a fast and uniform initial preload. The solution incorporates Boltight hydraulic tensioning with state of the art seal and pressure design.
    The achieved preload of VersaTite products is easily controlled by mechanically applying the final torque utilising Superbolt multi-jackbolt tensioning.
    Removal is just as versatile – either mechanical or hydraulic removal is possible. The operator chooses depending on location, amount of fasteners, space constraints as well as time and tooling availability.
    “Superbolt VersaTite is a result of our efforts to understand and solve the challenges our customers face,” comments Steve Busalacchi, tensioning specialist from the Nord-Lock Group. “Versatility in assembly and removal; safe and efficient operations; and increased application uptime; are some advantages the new solution brings. The new product truly offers versatility in one nut – that is why we named it VersaTite. No drawbacks – just added benefits.”
