How to Install Hi Lok Fasteners

Hi Lok Fasteners are widely used in the aviation and aerospace industries due to their high-quality, strength, and reliability. They are commonly used to join two parts together in an aircraft or other aerospace equipment. In this article, we will be discussing how to install Hi Lok Fasteners in a step-by-step manner.


Before installing Hi Lok Fasteners, it is essential to prepare the materials and follow basic safety precautions. The following are the essential materials you should have:

- Hi-Lok Fasteners

- Hi-Lok Collars

- Bolts

- Torque wrench

- Drill and drill bits

- Rivet gun

- Safety goggles

- Gloves

It is also crucial to follow all the relevant safety standards and regulations in your industry. Wear protective goggles and gloves during the installation process to avoid injuries from flying debris or sharp edges.

Step 1: Drilling

The first step in installing Hi Lok Fasteners is drilling holes in the parts that need to be joined. These holes must be clean, free of burrs, and match the size of the Hi Lok Fasteners.

Start by using a drill bit to drill holes in the parts that are to be fastened. Use a drill bit that matches the size of the Hi Lok fastener to ensure a tight fit.

Step 2: Inserting the Hi Lok Fastener

Insert the Hi Lok Fastener into the hole you drilled. One end of the Hi Lok Fastener must protrude from one side of the two parts that you are joining, while the other end should protrude from the opposite side.

Make sure that the Hi Lok Fastener is positioned correctly before moving to the next step.

Step 3: Installing the Hi Lok Collar

Place the Hi Lok Collar over the protruding end of the Hi Lok Fastener to secure it. The collar should be pushed onto the fastener until it fits firmly.

Make sure that the collar is completely secured and is not loose. A loose collar can cause the Hi Lok Fastener to fail, which can result in a hazardous situation in high-stress applications.

Step 4: Tightening the Hi Lok Collar

Using a Torque wrench, tighten the Hi Lok Collar to the manufacturer's recommended torque value. The collar should be tightened to its recommended value, which is typically provided by the manufacturer.

Be careful not to over-tighten the collar, as this could damage the Hi Lok Fastener or the parts that are being joined.

Step 5: Final touches

Finally, use a rivet gun to install the bolts that will provide additional support to the Hi Lok Fastener joint. Be sure to follow manufacturer guidelines to ensure that you install the bolts correctly.

Check the torque on the Hi Lok Fasteners and bolts to ensure that they are within the recommended values before moving on to the next part of your project.


Installing Hi Lok Fasteners is an essential process that should be done carefully and correctly. Following these steps should help you to install Hi Lok Fasteners correctly and ensure that they are secure, reliable, and long-lasting.

By taking the necessary steps to prepare before installation, drilling and inserting the Hi Lok Fastener correctly, installing and tightening the Hi Lok Collar, and tightening the bolts correctly, you can ensure that your applications are safe and secure.

In summary, follow these steps when installing Hi Lok Fasteners:

- Prepare your materials and follow relevant safety standards.

- Drill clean holes matching the size of the Hi Lok Fasteners.

- Insert the Hi Lok Fastener into the drilled holes.

- Install and secure the Hi Lok Collar.

- Tighten the Hi Lok Collar to the manufacturer's recommended torque value.

- Use a rivet gun to install bolts for additional support.

By following these steps, you can ensure that your Hi Lok Fastener installation is successful, safe, and reliable.
