About Taper Washer
Taper washers are square washers with one sloping face. They sit on the angled inside flange of a steel channel or I-beam so the bolt head or nut bears flat, not at an angle.
- DIN 434 for U channels (ISMC)
- DIN 435 for I-beams (ISMB)
Essential for structural steel, sheds and industrial frames.
Common applications
- Bolting to ISMC channels and ISMB beams
- Structural steel work and sheds
Frequently asked questions
›Why is a taper washer needed on channels?
The inside flange of a channel or I-beam slopes. Without a taper washer the bolt sits at an angle and bends when tightened.
