Abstract

This product is a washer used to support a sheathing board by attaching it to the threaded rod (bolt) of a concrete formwork fastener and tightening it with a nut, for example, as shown in the reference diagram showing the state of use, thereby pressing a square cross-section thick-end material such as a square pipe against a shallow beam.
