WHAT IT IS

Formwork tie rod with wing nut and cone is a through-wall tensioning assembly that prevents wall and column forms from blowing out under the hydrostatic pressure of wet concrete. The threaded DW-type steel rod passes through opposing formwork panels; plastic cone spacers set the wall thickness and leave a conical void in the hardened concrete face for patching after striking; wing nuts on each face tension the assembly. Diameter options DW15 (15 mm), DW17, DW20; typical breaking load 80–100 kN for DW15. Steel grade S235 or S355 to BS EN 10025. Used in wall, retaining structure, and basement formwork across Malaysia.
