Stainless Steel Eye Lag Screws for Use in Wood - 3"

  • RoHS Compliant

W300CSS 316 Stainless Steel I-Lag™™ screw is designed to fasten ceiling wire or jack chain to wood surfaces to facilitate the installation of drop ceilings in corrosive or marine environments.
The W300CSS is an excellent choice for MRI room applications due to it's austenitic, non-magnetic properties.
Chlorinated environments have been observed to cause stress corrosion cracks in 316 stainless steel. Check with your local AHJ (Authority Having Jurisdiction) before using the W300CSS in indoor pool applications.

Finding the right cable management solution for interior applications can be daunting. However, cable management tools for outdoor applications present a whole different set of challenges – the greatest of which is corrosion.  

Corrosion and metals do not work well together. Therefore, you should choose the right tools for your outdoor cable management needs to ensure that they perform their functions effectively.

At, our stainless steel eye lag screws offer the perfect solution for ceiling, wire and cable support.

What Are Stainless Steel Eye Lag Screws?

Stainless steel eye lag screws, as their name suggests, are cabling tools composed mainly of stainless steel. Stainless steel is a carbon steel alloy infused with a minimum of 10.5% chromium by weight. This material may also contain small amounts of other elements, such as nickel, manganese, copper, and molybdenum.

One of the most significant benefits of stainless steel is its resistance to corrosion. This makes our stainless steel eye lag screws ideal for damp indoor or harsh outdoor environments.

Why Is Stainless Steel Corrosion Resistant?

The chromium content in the steel alloy gives the bridle rings their corrosion resistance by allowing a thin protective layer to form on the ring's surface. As the stainless steel ring is exposed to water and oxygen in the atmosphere, a protective chromium oxide layer is formed. This layer, also known as a passive layer, prevents corrosion from forming at the surface.

What Are Some of the Advantages of Using Stainless Steel Eye Lag Screws?

In addition to improved corrosion resistance, stainless steel eye lag screws also offer several other benefits. These include:

Increased Longevity

Corrosion can cause metal thinning, which can drastically reduce the load-carrying capacity of your eye lag screw. This can ultimately lead to failures, such as cracking, bending, and breakage. The durability of stainless steel screws allows them to be used for a long time in harsh outdoor environments, so you won't have to think about replacing them any time soon.


Adding extra alloying elements to the steel increases the initial cost of the material. However, since they are highly resistant to corrosion, stainless steel eye screws last longer and perform better in outdoor environments. These characteristics make them more cost-effective in the long term as they can remain in service for decades without needing to be replaced.

Low Maintenance

Not only does the thin passive layer prevent air and moisture from contacting the screw substrate, but the layer also has self-healing properties. If the ring has a scratch, dent, or any other physical distortion, the bare alloy gets exposed. When this happens, the exposed chromium reacts with air and moisture to form another chromium oxide layer, which protects the ring from further corrosion. As a result, you won't have to worry about repairing or replacing eye screws for light defects.

Stainless steel eye lag screws are something you definitely want to consider in your next outdoor or indoor cable management project. They are also ideal for indoor applications near marine or industrial environments where corrosion rates can be accelerated.
