Clamping Advantage

Clamping Advantage

  • Up to 500% more clamping force compared to mechanical nuts.
  • Larger thrust rings, 4140 alloy steel components, and proprietary dual durometer seals provide superior clamping force in comparison to any competitive hydraulic nut supplier.
  • Self-aligning thrust ring provides uniform 360º contact with mating tooling.
  • Adjustable pressure Amtec pumps grant controllable clamping force for F-Type & GX-Type Nuts.
  • Custom threaded to suit existing international standard specifications.
Reliability & Durability

Reliability & Durability

  • 300% longer service life with 4140 steel or aircraft aluminum nut bodies, precision thrust rings and dual durometer seals.
  • Sealing system allows up to 3 weeks in-service time without significant pressure drop.
  • Amtec’s leak proof F-Nipples (for grease) and GX-Nipples (for oil) made from high strength steel bodies with high-pressure check valves to maintain positive pressure retention.
  • Precision actuator piston assemblies provide extreme pressure output for K-Type Nuts.
  • Thread wear is no longer a problem with proper thread matching and Amtec’s special OD-centering.
  • Bearing damage from hammering mechanical nuts is eliminated by our easy installation.
