I have been doing business with Military Fasteners for a number of years. Every Time I have needed a question answered in finding something for my projects Military Fasteners has always been there. The people I talk to are helpful and knowledgeable concerning all the vintage planes I have called looking for a special item needed. Thank you for being YOU!

Excellent service, parts arrived at my home in UK exactly when you said they would even when you did not have parts in stock when ordered, very prompt reply to my queries before ordering, faster delivery than I would have got from UK.

I love your website. Can hardly believe how fast & accurate the orders come. Am building a kit plane, need a lot of small hardware and electrical the past few months. There has not been a mistake in the last dozen orders.
