These are not like other terminals made with brass that break or loosen prematurely. These have the highest grade copper cores for maximum conductivity with an electro-tin plating to resist corrosion. The molded vinyl insulation prevents the terminal from pushing out of the other side, which happens with most other terminals out there. These terminals are engineered to hold the strongest crimp.
