You folks have always treated me well and supplied the product I needed, and the product I ordered and in a timely manner. I am working to build a Wag Aero Sport Trainer.

5.0

Have placed many orders in the past months with sales representative Brittany Cornish and couldn't be more pleased ! She is always a joy to speak with, and she always makes sure that my orders are delivered on time. She's a great asset to your team but I'm sure you already know that.

Military Fasteners is one of my top hardware suppliers. If you can't find a mil-spec part, they will find it for you. Shipping is always fast and reliable. Kristen is phenomenal to work with. Highly recommend.
