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!
