Airloc fasteners

Airlok fasteners were part of the product line of the Carr fastener Co. of Cambridge Mass.  The company started out making snap fasteners to hold the side curtains of early, “open” automobiles but soon broadened its product line to include fasteners for clothing, automobiles, boats and airplane curtains, as well as radio tube pins, clips and sockets. 

There was a Canadian factory, located in Hamilton. In 1928, this plant became the United-Carr Fastener Company, when its parent company merged with the United States Fastener Company of Boston, Massachusetts.The plant was dramatically expanded. By the late 1930s, over 150 men and women were working here.

After World War II, the company also began producing precision-made parts, such as pen and pencil components, television connectors and screw shells for electric lights and fuses. In the 1960s, production was transferred to a 75,000-square-foot facility in Stoney Creek. Airlok fasteners are still available today.

 The somewhat odd-looking Curtiss Wright AT-9 in the ad was built as an intermediate trainer during WW2. It was a difficult aircraft to fly and after WW2 they were scrapped instead of being released for civilian use. Nearly 800 were built.

 Image below shows the parts that make up an Airloc fastener. The system consists of a receptacle, a stud, and a cross pin. The stud is attached to the access panel and is held in place by the cross pin. The receptacle is riveted to the access panel frame.
