Abstract

A nested locknut wrench system includes a first wrench and a second wrench. Each wrench has a base portion having a flat portion including at least one magnet. Each wrench has a first extension portion extending perpendicularly from a first end of the base portion. Each wrench has a first arc-shaped finger extending perpendicularly from the first extension portion and having a first hook member extending radially inward from the first arc-shaped finger. Each wrench has a second extension portion extending perpendicularly from a second end of the base portion opposite the first end. Each wrench has a second arc-shaped finger extending perpendicularly from the second extension portion and having a second hook member extending radially inward from the second arc-shaped finger.

First claim

What is claimed is:

1. A nested locknut wrench system comprising:
a first wrench and a second wrench, each having:
an elongated base portion having a first magnet at a first end and a second magnet at a second end opposite the first end;
a first end portion extending from the base portion, the first end portion including a first arc-shaped finger offset from the base portion and having a first hook member extending radially inward from the first arc-shaped finger; and
a second end portion extending from the base portion, opposite the first end portion, the second end portion including a second arc-shaped finger offset from the base portion and having a second hook member extending radially inward from the second arc-shaped finger
wherein when the elongated base portion of the first wrench is stacked on the elongated base of the second wrench, the first magnet and the second magnet of the first wrench or the first magnet and the second magnet of the second wrench retains the first wrench to the second wrench; and
wherein when the first wrench is retained to the second wrench, the first magnet of the first wrench is offset from the first magnet of the second wrench.

2. The nested locknut wrench system of claim 1 , wherein, when first wrench is retained to the second wrench, the second magnet of the first wrench is offset from the second magnet of the second wrench.

3. The nested locknut wrench system of claim 1 , wherein:
the first end portion includes a first extension portion extending perpendicularly and between the base portion and the first hook member; and
the second end portion includes a second extension portion extending perpendicularly and between the base portion and the second hook member.

4. The nested locknut wrench system of claim 3 , wherein the first end portion and the second end portion extend in opposite directions from the base portion.

5. The nested locknut wrench system of claim 1 , further comprising a third wrench having:
a second extended base portion having a third magnet at a third end and a fourth magnet at a fourth end opposite the third end;
a third end portion extending from the base portion, the third end portion including a third arc-shaped finger offset from the second base portion and having a third hook member extending radially inward from the third arc-shaped finger; and
a fourth end portion extending from the base portion, opposite the third end portion, the fourth end portion including a fourth arc-shaped finger offset from the second base portion and having a fourth hook member extending radially inward from the fourth arc-shaped finger.
