This is just a note to say how much I appreciate Military Fasteners. Your prices are fair, your shipping is fast and the costs are reasonable. The paper and online catalogs have a huge assortment of products. I also like the fact that there is no minimum order.

5.0

Love working with this company. Customer service is always so kind and helpful.

5.0

I am unable to add any suggestions. Military Fasteners is an on time provider. I have never understood why the orders from you company are shipped and arrive in time given to me. Other companies say same day ship or the following day and it takes much much longer for the product to arrive. All I say, Good Job

5.0

Ordered the plugs on Tuesday and received them Friday morning. Great service. Items arrived as ordered. You run a tight ship.
