WHats the difference?

Lets start by saying that both brands of concrete screws get the job done.. and done well.  As we continue to expand our product inventory to best serve our customers and their customers needs, we are making sure to facilitate other industries such as Windows & Doors the fasteners their installation crews need at the job. 

Both the MILLFAST and ELCO brands carry carbon steel Phillips head and TrimFit screws in different sizes for many applications.

MILLFAST concrete screws are ASTM-B117 salt spray tested and cerami-coated.

 Elco Ultracon offers a stainless steel line along with a Miami-Dade county product approval.
