Zoro Tools has a simple mission—
We help small business stay competitive!

We do this by offering more than 375,000 great products at super low prices. Small businesses have historically been at a disadvantage to larger companies who can buy stuff at lower prices because of their size. We want to change that!

Zoro Tools has most of the products that the “big guys” have and we offer every single one of them at an everyday low price. There are no complex discount structures to understand and no hidden costs. Every customer pays the same low price for an item—whether you want to buy one or one thousand!

Like you, we believe that the key to success is to always put our customers first.

meet the staff

We live for the moments that we can make
you happy—that’s the truth!

Most of our business occurs through the internet. However, we know that there are times when you need to communicate with a person. Our customer service staff is here to help you. You can contact us in the way that works best for you.

Our customer service hours are Monday thru Friday from 7AM to 7PM (CST).

Using Our Site

Zoro Tools has designed a unique and intuitive product search feature.

All you need to do is select the product attribute values you are looking for within your search results (size, color, material, etc.) by clicking on the value you want, and the products that meet the criteria you have chosen are immediately shown in a table right below where you made your selections.

The more specific you are in your attribute selections—the narrower the search results will become in your very own “custom made” product table!

If you prefer to search using manufacturer model #, a competitor’s part number or a Zoro Tools part number, just enter that number into the “search bar” at the top of the page, you will immediately be taken to a page that contains the item.
