Customer Reviews

Best source for mil spec hardware. Website is user friendly, inventory is expansive, overnight shipment is a huge plus, and customer support is responsive and very helpful.
Excellent service, parts arrived at my home in UK exactly when you said they would even when you did not have parts in stock when ordered, very prompt reply to my queries before ordering, faster delivery than I would have got from UK.
ABSOLUTELY AWESOME!!!!
Ordering is simple and my parts are always shipped promptly and arrive well packaged. Military Fasteners is always my go-to store when I need something for my homebuilt project.
