Why Use Amtec?

Amtec Hydraclamp is committed to technical innovation, custom engineering, and quality control designed to solve our clients’ operating challenges and improve their productivity, quality, safety and profitability.


Clamping Advantage

  • Up to 500% more clamping force compared to mechanical nuts
  • Larger thrust rings, alloy steel components, and heavy duty “U”-cup seals provide superior clamping force in comparison to any competitive hydraulic nut supplier
  • Self-aligning thrust ring ensures uniform 360° contact with mating tooling
  • Adjustable pressure pumps provide controllable clamping force for F-Type and GX-Type Nuts also known as Jetnuts
  • Threaded to suit existing International standard specifications


Reliability & Durability

  • 300% longer service life with alloy steel nut bodies, precision thrust rings and dual hardness seals
  • Sealing system allows up to 3 weeks “in-service” time without significant pressure drop
  • “Leak proof” F-Nipples (for grease) and GX-Nipples (for oil) provide alloy steel bodies and check valves to ensure positive pressure retention
  • Precision Actuator Piston assemblies ensure positive pressure output for K-Type Nuts
  • Thread wear is no longer a problem with proper thread matching
  • Bearing damage, from hammering mechanical nuts, is eliminated
  • Black-oxide finish prevents oxidation on steel nut bodies



  • Amtec nuts are safety-engineered to meet operating requirements
  • Hammers and wrenches are not required; only an L-Type hex wrench, small assist bar and portable pump
  • Choice of peripheral or end face access for operator convenience
  • F-Nipples, GX-Nipples and Actuator Pistons are fully recessed for protection against physical or mechanical damage
  • Knurled outside diameter for better grip
  • Aluminium nut bodies offer 60% weight reduction vs. steel in F-Type Nuts


Custom Engineering

  • Custom designed devices with integrated pressure control systems and quick disconnect fittings are available
  • Safe, convenient and durable, Amtec pressure control systems have been custom-engineered for grease or oil at operating pressures up to 700 bar (10,150 psi)
  • Special seals can be installed for high temperature use
  • Extra corrosion resistance through use of electroless nickel, chrome plating or stainless steel
