Nut style Multi-Jackbolt Tensioners from Superbolt® are an innovative bolting product that will eliminate expensive and dangerous tooling. Only hand/air tools are required to install or remove any size Torquenut™.

Below are a few of the series available.

MT Torquenut™

Uses: Standard Multi-Jackbolt Tensioner.

Operating Temp: -50ºF to 500ºF

Description: MT tensioners are used on general mechanical applications. They can be used on high or medium strength bolts and studs and will fit in the same area as a heavy hex nut. The MT series features hex-head jackbolts.

Application Examples: General machinery, mining equipment, anchorbolts, gear boxes, pinion stands, tables, crushers, engines, compressors, presses, etc.

CY Torquenut™

Uses: Higher strength alternaitve to MT Tensioner.

Operating Temp: -150ºF to 500ºF*
(*additional material testing required for low temperature service)

Description: CY series tensioners are used for higher bolt loads on general machinery applications. They fit in the same area as a heavy hex nut.

Application Examples: Semi-cryogenic bolting, compressors, pumps, high pressure flanges, pinion stands, gear reducers, gear boxes, split gears, crushing equipment, presses, and military equipment.

MTSX Torquenut™

Uses: For higher preload needs, extra high strength.

Operating Temp: -50ºF to 500ºF

Description: MTSX Torquenuts provide extremely high preloads on large bolts or studs. Relatively little jackbolt torque is required by using JL-M lubricant.

SJX Jamnuts

Operating Temp: -50ºF to 500ºF

Description: SJX Jamnuts are used for applications where limited headroom and/or limited thread engagement are required. On request jamnuts are available with Superbolt's® patented captive set screws.

Application Examples: Hydraulic cylinders, shaft mounts, pipe flanges, and inaccessible places.

SMX Mill Motor Nuts

Operating Temp: -50ºF to 500ºF

Description: 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.

Application Examples: Mill motor nut on brake wheel.

NI Bearing Locknuts

Operating Temp: -50ºF to 500ºF

Description: NI bearing lock nuts are directly interchangeable with standard AN and N series locknuts. Bearing locknuts are ideal for jacking bearings into place. They can also clamp entire shaft assemblies.

Application Examples: Common bearings.

MTA - Armored

Operating Temp: -50ºF to 500ºF

Description: Superbolt® Armored Torquenuts™ are used primarily for rough service environments. The jackbolts are recessed in the nut or bolt body protecting them from flying debris or rotating parts.

Application Examples: Mining equipment, anchorbolts, gear boxes, pinion stands, tables, crushers, engines, compressors, presses, etc..
