Continental-Aero's History


Sid Greendorfer recognized the need for significantly better Locknuts and searched for a Source. He found one, in Firth Cleveland, a British Fastener manufacturer of All Metal and Nylon Insert Locknuts. To market these products, he began the Aero Stop Nut Division. He hired Jerry Badner as its first salesman, who would stay for twenty-two years, culminating his career as the Division's Vice-President. Aero grew to become the largest vendor of Nylon Insert Locknuts in the U.S.


Ted Jarman also realized the potential in selling nylon insert locknuts. In 1966, he started Continental Fasteners and was the first to import locknuts with a branded nylon insert from Japan. Much of the original tooling in Japan originated with Continental. When production shifted from Japan to Taiwan, Continental drawings and specs accompanied the tooling. Continental recognized the marketing potential of making the product with a traceable, fully recognizable color for the nylon insert. The ROYAL PURPLE TORK LOK NUT was created.


Fastener City was sold by Sid Greendorfer to HMW Industries and he left the company. Sid's relatives, Bob Greendorfer and Leonard Robinowitz also eventually left.


Continental Fasteners, which had been acquired by a Japanese company, Kobayashi Metals, was sold to Mr. Robinowitz.


Aero Stop Nut, which at that time, was owned by Schaefer Supply, was also purchased by Leonard Robinowitz. The business began to grow by leaps and bounds. Catching a rising market throughout the 1980's and 90's, the company captured a significant market share of the nylon insert market.


Continental Fasteners and Aero Stop Nut were combined and renamed as Continental-Aero. In 1999, Continental-Aero hired Bill Giddins as a consultant. One week after purchasing Continental, Lenny hired Marty Schneider. Marty sunk his teeth into the business and became the president of Continental-Aero.


Bill Giddins became Vice President of Continental-Aero. The Continental-Aero team was in place and expansion of the company continued with the addition of stocking warehouses: Pacific Warehouse in Santa Fe Springs (LA Metro) and Assembly Products Arlington (Dallas Metro). These locations allow Continental-Aero customers to speak with sales people from 7:30 am, East Coast time, to 6:00 PM West Coast Time.


Ms. Kelly Wiechen was hired for operations. She led Continental-Aero's transition from Niles, IL to Alsip, IL in 2008. That year, she was promoted to Head of Operations. In 2004, Continental instituted strict policies on procurement to ensure that its sources of supply comply with its exacting quality requirements. The founders of Continental Fasteners and Aero-Stop Nut and the current management of Continental-Aero are dedicated to satisfying its customers.


Bill Giddins became the Chief Executive Office, and Kelly Wiechen became the Chief Operating Officer.

Continental-Aero was acquired by Tramec, LLC.


Encouraging attendees to take catalogs at trade shows can be challenging, but the allure of free gifts, especially those with intrinsic value, offers a promising solution. To address this, Continental-Aero adopted the strategy of distributing toy trucks as giveaways.

Matchbox has long made branded cars and trucks for companies. These promo designs are never sold retail, but rather given away as a promotion with a proof-of-purchase. Through negotiations, we persuaded Matchbox to create limited runs for us. The inaugural set of four trucks was restricted to 5,000 units each, while Truck #5 and Truck #6 saw an increase to 10,000 pieces each. Surprisingly, the Continental-Aero purple trucks evolved into sought-after collectibles.

Primarily distributed at trade shows and during sales calls to current and potential clients, these trucks are relatively scarce in circulation. The limited availability contributes to an increase in their market value. Moreover, enthusiasts who avidly collect specific truck models, such as the 'Model T' and 'Model A,' further fuel the trucks' collectible status.
