A wrench head comprises a working axis, a first jaw, a second jaw, and a third jaw. The first jaw comprises a first-jaw arcuate convex contact surface, a second first-jaw arcuate convex contact surface, a third first-jaw arcuate convex contact surface, and a first-jaw planar contact surface. The second jaw is coupled with and pivotable relative to the first jaw and comprises a second-jaw arcuate convex contact surface and a second-jaw planar contact surface. The third jaw is coupled with and pivotable relative to the second jaw and comprises third-jaw arcuate convex contact surfaces.

A device for removing an oil filter includes a sleeve. The sleeve includes a grip portion and a reservoir portion. The grip portion includes a wall and a plurality of spacer ribs. The wall is disposed about an axis and defines a filter cavity open through a first end of the grip portion to receive the oil filter therein. The spacer ribs extend radially inward from the wall and are configured to engage the filter. The reservoir portion extends from a second end of the grip portion and defines a reservoir cavity open to the filter cavity. The sleeve is movable between an extended position in which the reservoir portion is below the grip portion and a nested position in which the reservoir portion is at least partially nested within the grip portion.

A rod tightening tool includes an elongated member, a clamping assembly and a wrench attachment end. The elongated member has a semi-hollow interior and defines an opening at one end thereof providing access to the semi-hollow interior. The elongated member has a slot formed along a portion thereof that extends to the semi-hollow interior. The clamping assembly has a first member and a second member. The first member is installed for sliding movement along an exterior surface of the elongated member. The second member is installed to the first member such that the first and second members clamp to the elongated member. The wrench attachment end is fixedly attached to the elongated member.
