PreTect™ Threaded Masking Plugs

PEM PreTect™ Threaded Masking Plugs are designed to protect threads from paint and powder-coating processes on standard-type self-clinching nuts. The masking plugs are available in a variety of thread sizes and materials, including heat-treated carbon steel. The PEM PreTect Threaded Masking Plugs withstand temperatures up to 250°C, which reduces user labor and increases production throughput. The PreTect fasteners are shipped with the plugs in place, though they are easily removed with a fine tip tool.
