Tongue-and-groove pliers are a type of slip-joint pliers. They are also known as water pump pliers, adjustable pliers, slippy pliers, groove-joint pliers, arc-joint pliers, Multi-Grips, tap or pipe spanners, gland pliers and Channellocks (i.e., Channellock brand pliers).
They have serrated jaws generally set 45 to 60 degrees from the handles. The lower jaw can be moved to a number of positions by sliding along a tracking section under the upper jaw. An advantage of this design is that the pliers can adjust to a number of sizes without the distance in the handle growing wider. These pliers often have long handles—commonly 9.5 to 12 inches long—for increased leverage. The weight of the tool can also vary, depending on the material used.
Description:
- Easy, convenient engagement in 5 different positions due to milled tongue
- Self-locking on pipes and nuts: no slipping on the workpiece and low handforce required
- Non-slip joint
- Jaw profile designed to fit screws and nuts
- Joint design reduces strain of the centre bolt, hence no wear on pivot
- Guard prevents operators’ fingers being pinched
- Gripping surfaces with special hardened teeth, teeth hardness approx. 61 HRC for tool length 250 mm: high wear resistance and stable gripping
- Chrome vanadium electric steel, forged, multi stage oil-hardened
Atramentizing is a corrosion protection process in which steel is coated with phosphate using a zinc phosphate solution at 90° C (194° F).
