Superbolt was the world’s first to revolutionize nuts and bolts with multi-jackbolt tensioning (MJT) technology. Our technology has been proven in tens of thousands of successful installations and we continue to develop a multitude of solutions to solve the next generation of bolting challenges.
Expansion Sleeves Coupling Bolts
Superbolt expansion bolts are truly fitted into the hole due to the radial expansion of the conical bore sleeve.
By design, accurate radial force combined with the known axial clamping load, provides total protection against coupling slippage and thus prevents bolt and hole damage during subsequent removals.
The expansion bolts can be retrofitted to replace traditional interference or force fitted bolts, reliably and cost-effectively.
Standard Range
EzFit mechanical expansion bolts can be designed using latest FEA technology for any type of coupling with bolts of diameter 20mm (3/4″) or upwards.
Unique features and advantages of both hydraulic and mechanical expansion sleeve coupling bolts can be combined to best suit your specific requirements.
 | A Type Mechanical expansion bolt for threadless bore Access and operation from one side Dimension on request |
 | B Type Mechanical expansion bolt for blind holes Access and operation from one side ∅ 28 – 165mm |
 | C Type Mechanical expansion bolt for through-holes Access and operation from both sides ∅ 28 – 165mm |
SUPERIOR PERFORMANCE
EzFit mechanical expansion bolts are used on many critical applications throughout various industries, such as couplings on ship drives, turbines, engines, generators, compressors, and replacement for dowel pins in transmitting transversal loads on foundation anchors.
Advantages
- Quick and easy to install and remove – only hand tools needed
- No need for special high-powered tools and bolt deep freezing
- Saves money over alternative solutions in time and tooling
- Reusable split sleeve that springs back to original size, use after use
