Controlled torque on the bolts that matter. A hydraulic torque wrench does what a rattle gun and a bar cannot – it applies a known, repeatable torque to a big fastener, quietly, in a confined space, without three people hanging off a slugger. These are Protorc units running at 700 bar off a torque wrench pump.

Two families. Square drive wrenches take standard impact sockets and cover 164 Nm up to 69,247 Nm – the general purpose choice. Low clearance wrenches use a hex cassette or a link that slips over the nut itself, for flange joints and structures where there is no room for a socket and a drive.

Everything here needs three things to work: the wrench, a torque wrench pump, and a hose set. Pumps and twin line hoses are separate listings, linked from each product page. If you tell us the bolt size, the torque figure and how much room you have, we will put the right combination together.
