No special precautions are necessary when using bolt caps. Reasonable care should be taken when installing to avoid contact with the internal clips. Bolt caps are manufactured from a specially formulated compound which is stable and inert under normal atmospheric conditions. When subject to prolonged exposure above 1,200 degrees C the Cap will very gradually harden leaving a grey product form. Bolt Caps may be disposed of as normal household waste where permitted by the Local Authority. Click Here for H&S data PDF download
