Since 1938, Zephyr has established a reputation as a leading designer and manufacturer of assembly tools and tooling systems for the aerospace industry.

Today, Zephyr offers the industry a wide selection of screwdriver bits and specialized tools for assembly. Many offer innovative design features that add quality to a product's fit and finish and increase productivity.

Zephyr has consistently met and exceeded the exacting specifications of the aerospace industry, general assembly industry, and U.S. Government with standard and specialized assembly tools.

Zephyr began its operations at its present site in Inglewood, California. At that time, its original founder, Mr. Don Dotson who was then a Regional Sales Manager for Chicago Pneumatic Tool, saw the need for a specialized tool manufacturer to support the growing west coast aircraft industry. Original customers included Boeing, Douglas Aircraft, North American Aviation, Rohr, Ryan Aviation, Northrop and Lockheed, to name a few. Mr. Dotson successfully built the company in its early years to become the premier specialty tool supplier in this growing aircraft industry. It was this birth that gave rise to Zephyr becoming a household word at aviation customers. Today, Zephyr is known for its outstanding quality, and in many circles, considered to offer the best available tools on the market.

Mr. Dotson continued to build the company through the early 40's, providing a significant effort in supporting the War effort. In 1945, to further help in the operation of the company, Mr. Dotson took on an equal partner, Mr. Jay Harkey. Together, Dotson and Harkey ran the company until 1969, when Mr. Dotson passed away. At that time, Mr. Harkey took control of the company and ran it until 1978, when he sold the company to a St. Louis investor, Mr. Lunsford. Lunsford owned the company until the end of 1980, when it was sold to Standun Inc., its now parent company.

The current management team at Zephyr has worked together for more than 15 years and there has been little turnover in key positions.
