Excellent!

I purchased a few 7" SS bolts, nuts and washers for them for my boat. The order total was minimal and it was online and my first time using Fasteners Plus, so I wasn't sure when or if I would get them. However.....there were constant email updates from order acceptance to delivery and everything came well packaged and in good form. If my experience is indicative of their usual service, they are top notch and I run an aerospace fastener business for a living.

Bat House Latch

All of the hardware we use is 316 Marine Grade Stainless Steel. Our bird homes and bat houses are exposed to the elements 24-7 year round. Some are placed on coastal properties where salt air is hard on metals. We bought and have previously bought some of our supplies from these folks. They’ve always been friendly and professional with us.
