M3 Black Plastic Spacer Washers Male / Female Thread Hex Spacers Standoffs
Plastic hex spacer with female and male threads for electrical panel applications , generally , male threads length is same as the female threads length , chamfered end for male threads section and chamfered opening for female threads section , male threads can be screwed into female threads of another plastic hex spacer for connection .
Hex spacers are made from plastic material with fire resistant UL94V-2 so that they are can be used to electric parts for insulation .
Plastic hex spacers show good performances on electricity and thermology and physics , and perfect mechanical property as well .
