Quality parts - good price

Needed some stainless steel fasteners for my gate refresh and the local stores didnt have the correct size and would have been more costly.

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.
