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!

Ive been purchasing aircraft parts and hardware from Military Fasteners for over 4 years. That alone should speak volumes. Ive always received excellent customer service and the product quality is unrivaled. When I think of aircraft parts and accessories, Im thinking Military Fasteners. Keep up the excellent work folks! Regards, Ed

Always great with your orders. Ordered 2 tires on a Sunday and they were delivered on Tuesday with free shipping and no tax.

4.0

Amazingly prompt response! I ordered over 1000 items and couldn't believe it when there was an email waiting the following morning saying the items had been dispatched. Easy to track the package online. By comparison I ordered some items from another supplier 3 months ago and I'm still waiting, with no apologies or communication emanating from them to explain the delay.
