WREN Hex Cassette Torque Wrench Hex Cassette Long Bolt Hex Cassette Low Profile Torque wrench

Hex Cassette Low Clearance Wrenches offer flexability and versatility - other Torque Wrenches types cannot.

For Long Bolts:
tighten down thread by-hand, place Hex hydraulic torque wrench over the bolt, onto the nut like a Ring Spanner, the hard work is the Hydraulics job, use the Reaction Pawl to release the pressure and remove Tool - easy! Deep sockets are not "deep" enough to do this, no wonder its called the Hydraulic Ring Spanner.

Tightest Space around nut: when limited space means a nut is against a housing & a wrench + socket wont fit, the thin wall of the Hex Cassette Hydraulic Tool will fit where no other tool will!

The Low Clearance Hex Cassette Hydrauliclow profile Multipier models gice many solutions for difficult flanges, heat exchangers & pressure pipes for the Petrochemical industry. These tool with low clearance features solve access problems where no other tool is even close.

Low Clearance Hex Cassette Hydraulic Tools are the low clearance tool of first choice: like a ring-spanner connected with Torque Multiplier, they have a similar nose radius to impact sockets. These access tools get torque to be the bolts thought impossible.

Hex Reducers or InsertsHex Cassette Torque Wrench Reducer

Hex Reducers are used to step-down AF sizes within cassette links, therefore expanding the AF size range of one single Hex Casette (or Link)

Each Low Clearance Hex-Cassette Hydraulic Tool has a nose radius that campares with impact sockets. Thus a small-radius ensures this tool easy access to tight applications ie under pipe flanges. The "reducers" are fitted and secured with retainer rings if required.

NOTE: When selecting a reducer, make sure your reduced " radius clearance" will still permit tool access. Remember that using an Reducer, you INCREASE the total nose radius, thus requiring MORE space so to fit the Hex Tool.
