DYWIDAG-Systems - Nuts and Couplers
Flanged Wing Nut
The Flanged Wing Nut, which is available in five different diameters, differs from the Wing Nut by a larger pedestal allowing a direct bearing on walings. It can be screwed on or loosened using a hexagon wrench, threadbar or hammer.

Cast, galvanized
Slope Plate
Like the Combination Plate, the Slope Plate also features a wing nut that is undetachable from the plate. In the case of the Slope Plate, both the plate and the nut are cast. The articulation of the wing nut is approx. 15° for square plates and 5° for round plates.

Combination Plate
Combination Plates consist of a waler plate and a forged wing nut that are articulated (max. 5°) but undetachable. The load capacity for wood and steel walings corresponds to the values of the base plates.

Pressed Waler Plate
Pressed Waler Plates are used for timber or steel walings in conjunction with a winged nut or a hex nut for load transfer. The embossing of the plate increases its rigidity. Load capacity depends on the contact area, the admissible bearing pressure and the threadbar that is used.

Wing Nut
With different Waler Plates, Wing Nuts can be used as anchor nuts both for timber and steel walings. They can be fixed and loosened using a hexagon wrench or a threadbar. If necessary, a clamping effect can be attained or overcome by applying hammer strokes to the wings.

Counter Nut/Square Nut
Hex Nuts with low heights are used as counter nuts in order to achieve a slip-free bar connection despite the coarse thread. They are only designed for transferring the counter moment and cannot be used as anchor nuts.

Couplers
We offer different couplers for the force-fit connection of two threadbars. A stop pin in the middle of the coupler ensures an equal screwing-in length of both bars. Two fixed threadbars can be connected and tensioned using a turnbuckle splice.
