Customer Reviews

I called the customer service line just before Air Venture at Oshkosh to find out if they would have the parts I needed at their booth. The service rep on the phone was very helpful and was able to check the inventory that was taken to Oshkosh.I was told that the parts would not be available but could be shipped from the warehouse without delay. I ordered a full set of intake seals for a Continental 085 on the spot and they arrived in a few days. I am very happy with the service provided, and will be ordering more parts soon! Thank you Larry
QUICK AND EASY
Hello, I am an Estimator for CAMCO Mfg. Inc. We work with many Prime companies that require Military Fasteners. Kristen Belmont is always the first to respond and gives me great service! She guides me with her knowledge and treats me w/much respect (even when I don't know what I'm talking about) Out of all the outside sources I have to work with, I enjoy working with her best!
