A quality product and an even better quality of people at Military Fasteners! Thank you Military Fasteners!

5.0

Nice online shop, with very fast operation and high quality service. A bit expensive and without quantity discounts but worth the money in general.

4.0

As a race car owner and builder I find your pricing and selection of AN hardware and composite materials more than meet my needs and expectations.

Props to my saleslady (whose name I have sadly forgotten) for her can do attitude. Fast and efficient yet friendly and thorough. The items arrived nicely padded with brown paper. Im so happy youve stopped using those hard-to-dispose-of styrofoam peanuts. Fast to ship reasonable prices. Just excellent all around!
