Props to my saleslady (whose name I have sadly forgotten) for her can do attitude. Fast and efficient yet friendly and thorough. The items arrived nicely padded with brown paper. Im so happy youve stopped using those hard-to-dispose-of styrofoam peanuts. Fast to ship reasonable prices. Just excellent all around!

I routinely use Military Fasteners and have them on our Approved Vendor List. They already understand traceability requirements and their website always seems up to date and accurate. Same day shipping is a big deal for us as well."
