Fasteners Plus Washers

I ordered galvanized washers, anchor bolts, and nuts from Fasteners Plus. All of the order arrived in a very timely manner and as ordered. I highly recommend ordering from Fasteners Plus.

These guys always come through.

Had a critical deadline. Erecting a 100 year old bridge and realized we were short the bolt quantity needed. Called to verify shipment. Customer service was friendly and helpful. Got the fasteners on time and kept the crew working.

prompt delivery and great customer service

I've ordered several times from fasteners plus and they have consistently delivered my orders quickly and correctly. Their customer service has also been great when I have communicated with them. Should the need arise in the future I will definitely order from them again.
