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

Trisha Hawkins has been very helpful and easy to deal with. Any rush orders or just orders in general, she makes sure I get it within the time requested.

I recently had the pleasure of working with Military Fasteners and I couldn't be more satisfied with the experience. Trisha Hawkins provided exceptional customer service and went above and beyond to ensure I found exactly what I needed. The quality of the fasteners is top-notch and the delivery was prompt. I highly recommend Military Fasteners for their outstanding products and excellent service. Thank you, Trisha, for making the process so smooth and efficient!

Products are military grade MIL-SPEC as advertised. I was able to locate #10 locking counter-sunk nutplates when ALL other locations, including Aircraft-Spruce, could not supply.
