I've been buying from Military Fasteners for about 2 years. In that time, I don't ever recall having a bad experience. Please keep up the great work and continue offering the fair prices, fast shipping and excellent customer service.

Small order but all was in stock, sales rep was very friendly and made it a pleasure. Shipped and received quicker than expected.

I have only ordered from Military Fasteners once so far, but I can't even express how happy I was with our order. As a purchasing manager who deals with government contracts (and the strict requirements that come with them), I was beyond thrilled with the flawless paperwork that was provided (free of charge) with the products we ordered. Lindsey was a peach to interact with, and we received our order next day; one of the perks of having a warehouse close by. I am very much so looking forward to to ordering from them again! Response from the owner3 years ago Thank you so much Holly for the kind words. We constantly try and think of new ways to improve the experience for our customers. We strive to make the package presentation upon arrival how we would want as a customer. It truly is an honor to service our customers that support our government and military branches.
