I sent in my online order then within a minute I realized I left off an item. I sent a message that requested an item be added to avoid a second shipping cost. I received a reply the next morning that the item I wanted had been added successfully and my order would be delivered as promised. Thanks to your staff for the flexibility and the help with my online order.

My company works directly with Military Fasteners, and we have had nothing but positive experiences. Trisha Hawkins, in particular, has been our primary contact. She always responds quickly and works to make sure the order is correct and shipped on time. Military Fasteners is a trusted vendor of ours and we look forward to working with them again in the future!
