M5 Silicone Rubber Plug, or HAMMERHEADS offer the fastest hole masking system available, by virtue of not needing any orientation before insertion into the hole. After any cleaning operations, the M5 Silicone Rubber Plug HAMMERHEADS are simply pushed into the hole to be masked and given a quarter turn clockwise to lock them in place. They remain in place during coating and stoving, being pulled out with a twist, preferably while the component is still warm. Any coating build up can be removed by rubbing between forefinger and thumb, or in a rumbling machine.
M5 Silicone Rubber Plug will resist temperatures up to 315 °C, making all BAKEWELL parts ideal for masking in electro-static powder coating, E-CoaT, wet painting, plating and anodising.
The double ended design will give twice the life of a single ended tapered bung. M5 Silicone Rubber Plugs are colour coded for easy identification.
