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.

Any time I need anything it is here when I need it without question. I have tried other suppliers and ship dates are not honored sometimes it can take two weeks for item in their stock!! Thanks for being consistent and prompt.
