Bourke hole plug kit, comes with flat black screws and neoprene washers .
* some holes will need to be widened with a 13/64 drill bit or similar .
** we also recommend adding a little bit of silicone in the hole prior to securing the screws .
*** you may want to add a little loctite to the screws so they don’t back out and don’t over tighten the screws to the point that the washers bulges out .
