Among the features of ARG, SS, SD and BVS series strainers are provisions on the strainer cap for the use of a spanner wrench to loosen the cap before or after maintenance. Hand-tight is sufficient for a good seal for GROCO strainers with threaded caps, but some boaters may prefer to "snug" the cover beyond hand-tight.
NOTE: Do not use SW-2531 to tighten non-metallic caps.

Here’s a great purpose built tool that will save you time and aggravation. It is specifically designed for use on the wing nuts of intake and raw water strainers. No more boogering the soft bronze wing nuts with pliers or fighting for an angle to get a proper bite. Small and compact, it works in the tightest installations. No more rinsing the pliers in fresh water to keep them from rusting after the gush of raw water. The Key is made from 304 Stainless Steel and then electro polished for years of trouble free use. It comes with a small lanyard so you can hang one on each strainer, so the tool is right there when you need it. Also works great on marine batteries (with wing nuts) and portholes. It’s the perfect pocket tool for engineers.
