Bolt style Superbolt multi-jackbolt tensioners (MJTs) replace existing studs or bolts. Ideal for applications with tapped holes, or where
threading a stud into a nut would be impractical. The outside diameter is smaller than a nut type tensioner on a stud, allowing MJTs to fit
into tighter areas.
Superbolt products are an innovative technology for tightening large bolts & studs. MJTs have been proven and established as a preferred
solution for bolting in every major industry, all over the world. They offer you simple and cost effective tightening of large size bolts. Your
joints can be tightened with high accuracy without requiring specialist skills or heavy tooling. MJTs ensures a profitable life cycle cost by
improving the bolt design for OEM manufacturers, ensuring reliable operation and by facilitating maintenance procedures.
SB8 - Standard bolt
Bolt style multi-jackbolt tensioners (MJTs) from Superbolt are an innovative bolting product that eliminate expensive and dangerous tooling.
Only hand/air tools are required for installation and removal of any size tensioner.
Description:
Bolt style MJTs are most often used for applications with tapped holes. Additionally, the diameter of the head is smaller than a nut type
tensioner, allowing bolt style MJTs to fit tighter areas. They are also available for high temperature service and can be made from a variety
of materials.
Selection Guide:
• SB8 - Standard bolt
• Dimension range: M16-M160 (3/4" - 6")
• Approx. bolt stress depending on size: 400 to 650 N/mm2 (60 to 95 ksi)
• Temperature range: -10 to 250oC (0 to 500oF)
• Surface treatment: optional
• Application examples: Bolting applications in demanding industries
• Note: Equivalent nut-style tensioner is the MT
SB12 - High-strength bolt
Bolt style multi-jackbolt tensioners (MJTs) from Superbolt are an innovative bolting product that eliminate expensive and dangerous tooling.
Only hand/air tools are required for installation and removal of any size tensioner.
Description:
Bolt style SB12 MJTs offer higher strength and are more suitable for low temperatures. Other features are the same as the SB8.
Selection Guide:
• SB12 - Standard bolt
• Dimension range: M20-M90 (3/4" - 3-1/2")
• Approx. bolt stress depending on size: 500 to 850 N/mm2 (70 to 125 ksi)
• Temperature range: -10 to 250oC (0 to 500oF) - lower temperatures on demand
• Surface treatment: optional
• Application examples: Bolting applications in demanding industries, higher strength than SB8
• Note: Equivalent nut-style tensioner is the CY

What is a multi-jackbolt tensioner?
A "Superbolt" or "multi-jackbolt tensioner (MJT)" is a direct replacement for hex nuts, covered
nuts, bolts, etc. They spin onto your existing bolt or stud and provide a better way to bolt up your joint. They
consist of three components, shown above.
Superbolt multi-jackbolt tensioners (MJTs) replace existing hex nuts. Only hand tools are required for installation and removal of any size
tensioner. Safe, accurate and economical! We have a wide range of standard series, as well as an unlimited capacity to create special designs
to meet your unique needs.
Bolt style Superbolt multi-jackbolt tensioners (MJTs) replace existing studs or bolts. Ideal for applications with tapped holes, or where
threading a stud into a nut would be impractical. The outside diameter is smaller than a nut type tensioner on a stud, allowing MJTs to fit
into tighter areas.
Flexnuts are used in combination with Superbolt tensioners and are designed to flex out at the bottom and flex in toward the top of the nut.
This distributes the bolt load along many threads, adds elasticity, and prevents stress concentrations in the first few threads.
SMX Mill Motor Nuts are used to replace standard mill motor armature nuts supplied by electric motor manufacturers. SMX tensioners are available for most standard motor frame sizes. Preload matches the hub stress capacity of brake wheels and pulleys.
