Abstract

A hex wrench assembly includes a tubular body having a reinforcement protrusion extending radially outward from a mediate portion of the body. A plurality of passages are defined in the body and a plurality of recesses are defined radially in an outer periphery of the body. Each recess shares a common axis of respective one of the passages. The head of a hex wrench is inserted in the passage and the handle of the wrench extends out from the recess.

Claims

1. A hex wrench assembly comprising:

a tubular body having a plurality of passages defined therein and a plurality of recesses defined radially in an outer periphery of the body, each recess sharing a common axis of respective one of the passages, the length of each of the passages is equal to the length of each of the recesses, the passages and the recesses defined in each of two ends of the tubular body;

a plurality of hex wrenches each having a head and a handle, the handle removably inserted in one of the passages or recesses, and

a reinforcement protrusion extending radially outward from a mediate portion of an outer periphery of the body.

2. The hex wrench assembly as claimed in claim 1 wherein the passages and the recesses are located alternatively from each other when viewed from either one of the two ends of the tubular body.
