QH Ratchet Head

  • QH ratchet heads have a small tightening radius to facilitate effective tightening in cramped areas. The square drive QH10D-1/4, QH15D-3/8 and QH22D-1/2 models are one size smaller than the regular models, so their sockets are cheaper.
  • Ask for inventory status and price.

PH pipe wrench heads

  • With an ordinary wrench, applying torque control on piping or reinforcing screws and bolts may encounter wrench slippage because of the abscence of widths across flats. But with a PH pipe wrench head clamping is robust, facilitating torque control.
  • Ask for inventory status and price.

AH Adjustable Open End Head

  • The mouth width of AH adjustable open end heads can be adjusted, so there's no need to keep SH interchangeable heads on hand for each separate mouth width. This is especially convenient when working with hydro-pneumatic piping, for maintenance, and for torque control with inch-standard bolts.
  • Ask for inventory status and price.

SH-N Open End Head with Notch

  • SH-N models: The notch creates speed in the tightening process by grasping the side of the fastener without removing the wrench. This reduces the possibility of error-tightening.
  • Ask for inventory status and price.
