Have you ever heard of an Eye Screw? An Eye Screw is a screw with a loop or ring on one end instead of a traditional flat head. These unique screws come in various sizes and materials, making them highly versatile for many applications. Whether you need to secure objects or hang lightweight items, an Eye Screw can provide an easy and efficient solution. In this blog, we will explore the properties, uses, and applications of Eye Screws and how to use them effectively.

What is Eye Screw?

An eye screw, also known as a lag eye screw, is a type of screw with a looped head. Its main purpose is to form an attachment point for ropes and cables, allowing them to be easily secured and removed. The head of an eye screw typically consists of a metal loop with threading coming out from the side or center that allows it to be screwed into wood and other materials.

Properties of Eye Screws

Eye Screws are manufactured from various materials, including stainless steel, brass, and zinc. Some are also coated with black oxide, nickel, or zinc plating for added durability and protection from rust and corrosion. Depending on the intended use, the screw threads are either coarse or fine and are available in lengths ranging from half an inch to over six inches. The threading depth also varies to provide different grip strengths.

Common Uses and Applications

The primary purpose of an Eye Screw is to provide a secure hold for objects or to create a hanging point for lightweight items. Eye Screws can hang curtains, shades, blinds, chandeliers, pictures, and other decorative items. They are also commonly used in the manufacturing, construction, and transportation industries for carrying and securing loads. Eye Screws are especially helpful when working with wood, where they can prevent cracking and splitting.

Choosing the Right Eye Screw

Choosing the right Eye Screw depends on the intended application. The screw must be the right size and material to effectively hold the object’s weight and avoid damage. You will first need to determine the weight of the item being hung or secured and then select the appropriate size screw with adequate threading depth and load-carrying capacity. Eye Screws also come in varying threading patterns – coarse or fine. Coarse threads require less torque and are best suited for soft materials like wood. Fine threads require more torque and are used in hard materials like steel.

How to Use Eye Screws

Using Eye Screws is straightforward. Locate the point where you want to attach the Eye Screw and drill a pilot hole of the appropriate size. Screw the Eye Screw into the hole using your hand or pliers for a firmer grip. The pilot hole will prevent the wood from splitting, and the screw will hold tighter. Ensure to tighten the Eye Screw securely while ensuring it is straight, level, and at the desired depth.


Eye Screws provide a simple and effective solution for securing objects or creating hanging points for lightweight items. They come in various sizes, materials, and threading patterns, making them ideal for numerous applications.
