## Description

15 years in the making, NL-19 is Foreverbolt's proprietary lab-tested treatment that modifies the surface of stainless steel products, producing a brighter finish, increased strength, and superior corrosion resistance, all without affecting the fastener’s exterior dimensions. With more than 30 years of engineering and fabrication knowledge, we understand how to make a better fastener. The cost to prevent corrosion can be extensive when you factor in inspections, maintenance, repairs of parts, backup inventory, and refurbishment. The Foreverbolt NL-19 treatment is an advanced corrosion protection that can dramatically reduce future maintenance and repair costs.
