Caps for ARG, SS, SD and BVS series strainers have holes for the use of a spanner wrench to loosen the cap before or after maintenance. Hand-tight produces a sufficient 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.
