CONTROLLED BOLTING TOOLS

THE RIGHT BOLTING TOOL PERFORMS EVERY TIME

 
Torque Wrench Basics
Types of Torque Wrenches
Torque Wrench Types Functions Considerations Series      
Square Drive, Single Body Square drive wrench used in combination with sockets A single body design provides superior durability
S
   
Low Profile, Cassette Style A drive unit used in combination with hex cassettes The low-profile design is ideal for jobs with limited access or space constraints
W
 
Modular, Low Profile & Square Drive A single drive unit can operate both a low-profile hexagon cassette and a square drive cassette Interchangeable with cassettes and square drive heads provides superior versatility
Torque Wrench Features
Square Drive Features
  • Single Body & Modular: choice between single body wrenches and modular square drive cassettes
    • Single Body: a single body wrench provides superior durability (S-series & DSX-series)
    • Modular: a drive unit which operates low-profile cassettes of different A/F sizes as well as a square drive cassette. The modular, two tool design provides superior versatility (RSL-series & HMT-series)
  • Torque Output Range from 141 to 28,002 Ft.lbs
  • Material choice between steel and aluminum square drive wrenches; or combination (HMT-series)
    • Steel: superior durability (S-series & RSL-series)
    • Aluminum: superior portability (DSX-series)
  • Angle of Turn: measures the rotation of turn (S-series)
  • Safety Tether Point: connection for working at heights (DSX-series)
  • Handle: universal handle throughout the range
  • Hands-Free Operation: convert a square drive wrench into a hands-free tool with a Safe T Lock accessory provides improved operator safety by reducing pinch points (RSL-series & S-series)
  • Reaction Arms: 360 degrees click-on reaction arm (S-series)
  • Rotation Angle: a market superior 30-35 degree rotation angle per cycle increases productivity
Low profile cassette wrench features
  • Reduced torsional forces increases durability
  • Nose radius: small nose radius provides greater access to bolts with access limitations or space constraints
  • Torque Output Range: from 141 to 35,000 Ft.lbs
  • Quick Release Connection: a single trigger to easily swap out hex-cassettes (W-series)
  • Handle: universal handle throughout the range
  • Ultra Slim Cassettes are available for very tight access limitations or space constraints (W-series & RSL-series)
  • Rotation Angle: a market superior 30-35 degree rotation angle per cycle increases productivity
  • Interchangeability with other manufacturers cassettes (HMT-series)
Application Considerations
  • Access Limitations or Space Constraints
    • Low profile wrenches are ideal for applications with limited access
  • Required Torque
    • Tighten bolts: the torque required to fasten the nut
    • Untightening bolts: loosening a nut can take up to 250% of input torque
  • Frequency of Use
    • For high frequency of usage consider single body, steel wrenches (S-Series) or low-profile wrenches (W-Series), providing superior durability and reliability
  • ATEX Requirements
    • S, W, DSX and HMT-Series wrenches are all ATEX certified
  • Accessories
    • Special reaction arms, Allen drives, handles, Safe T Torque Locks
  • Working at Height
    • The tether point connection on DSX wrenches is ideal for working at height
  • Portability / Weight
    • The aluminum body DSX wrench is ideal when portability is critical
  • Speed
    • Enerpac wrenches offer increased productivity through a market superior 30-35 rotation angle per cycle
  • Pump Flow Rate
    • The flow rate of the pump will determine the speed of a hydraulic torque wrench. For time sensitive applications, select a pump with a higher flow rate
