What You'll Learn
Identify the type of rivet
Before you tighten a rivet on a pan, it is important to identify the type of rivet you are working with. There are four basic types of rivets: tubular, blind, solid, and split.
Solid rivets are the most common type of rivet. They consist of a solid shaft with a head on one side and are deformed using a rivet gun or hammer. The head can be rounded, conical, countersunk, flat, or oval. To install a solid rivet, it is placed into a pre-drilled hole, and then a hammer or rivet gun is used to deform the straight end into the required head shape. Solid rivets are used in critical applications such as vehicle bodies or structural members.
Tubular rivets are similar to solid rivets but have a hole on the straight side that travels a short distance into the shaft. They are designed to be easier to install as less force is required to deform them. Tubular rivets are used in low-risk applications such as HVAC ducting.
Blind rivets, also known as "pop rivets", are used when there is no access to the rear of the two parts being fastened. They are available in standard, structural, and closed-end styles, among others. A drive rivet is a type of blind rivet that is installed by driving the center pin into the body of the rivet using a hammer, causing the other end to flare out and fasten the materials together.
Identifying the type of rivet on your pan will help you determine the best approach to tightening it.

Use a block of metal or hard plastic to hammer the rivet
To tighten rivets on a pan, you can use a block of metal or hard plastic to hammer the rivet. This method is more secure and safer than simply hammering the rivet, which can cause the rivet to mushroom and push more material between the handle and the pan, or cause the rivet to crack.
Firstly, find a block of metal or hard plastic that fits inside the pan and is relatively close to the radius of the interior of the pan's diameter. If the interior of the pan is newly tinned or has a stainless or silver interior lining, put a cloth over the metal or plastic before placing the pan on it to protect the lining. If the pan has been stripped and cleaned and does not have a new tin lining, you can skip the cloth.
Hold the pan steady, with the rivet area you will be hammering directly in the centre of the interior fixture, and the rivet on the handle will be hammered from the inside. Make sure that only the rivet touches the metal or plastic block when you hammer the outside end of the rivet. If the pan touches the block during the hammering, it could dent. Hammer once firmly and check to see if the rivet has tightened. This will indicate whether you need to hammer again and with how much force. Repeat this process for all rivets.
The key is to ensure that there is a good backstop holding the interior rivet and a piece to hold over the rivet itself on the handle before hammering. This method will ensure that there is no direct pressure on the rivet itself but on the surface of the handle and the sides of the pot surrounding the rivet.

Ensure there's no direct pressure on the rivet
To tighten rivets on a pan, it is important to ensure that there is no direct pressure on the rivet. Here are some steps to achieve this:
Firstly, find a piece of metal or wood that can enclose the rivet on the handle. This will help distribute the pressure around the rivet and prevent direct impact on it. Make sure the piece of metal or wood is hollow enough to fit over the rivet securely. This method is much safer than directly hammering the rivet, which can cause further issues such as cracking or mushrooming of the rivet.
Next, you will need to prepare the pan for hammering. Find a block of metal or hard plastic that fits inside the pot and is close to the radius of the interior diameter. If the pot has a new tin lining or a stainless/silver interior, place a cloth over the metal or plastic to protect the lining from any potential damage. If the pot has been stripped and cleaned without a new lining, the protective cloth is not necessary. Ensure that the pan is held steady, with the rivet area you will be hammering directly in the centre.
Now, place the piece of wood or metal over the rivet on the handle. This will act as a protective layer and prevent direct contact with the rivet. Hold the pan in a stable position, ensuring that only the rivet will touch the hammer. If the pan comes into contact with the hammer during the process, it may result in dents or other damage.
Finally, hammer firmly on the outside rivet head. Start with a single firm strike and then assess if additional hammering is required. Repeat this process for any other loose rivets on the pan. Remember, the key is to distribute the pressure around the rivet and avoid direct impact, as this can cause further damage to the rivet or the pan itself.

Apply anti-seize lubricant
While tightening rivets on a pan, it is important to apply anti-seize lubricants with caution and precision. Anti-seize products are applied to bolts, fasteners, and other interfaces to prevent galling, seizing, and corrosion, as well as to ease disassembly. Here are some detailed instructions to effectively apply anti-seize lubricants:
First, ensure that the surfaces are clean and free from oil, grease, or any other contaminants. This step is crucial, especially if the components are supplied oiled. A dirty or contaminated surface can hinder the effectiveness of the anti-seize lubricant and may even cause damage.
Second, when applying the anti-seize lubricant, aim for a thin and uniform layer. A brush is typically the most effective tool to achieve this. Using a brush will result in a more even layer than using a gloved hand or finger, especially when applying the lubricant to threads. Make sure to use a dedicated brush for each type of anti-seize compound to avoid cross-contamination, as this can also impact performance.
Third, pay close attention to the amount of anti-seize lubricant you apply. A thin layer is generally sufficient. For a typical fastener assembly, a film approximately 0.1mm thick is recommended. Avoid over-applying the lubricant, as excess amounts can be wasteful and may even attract debris and contaminants, leading to thread damage and making it difficult to remove the fastener cleanly.
Fourth, be mindful of the torque specifications when using anti-seize lubricants. The lubricating properties of the compound can significantly decrease the required torque to achieve the desired clamping force. Consult the manufacturer's specifications to determine the exact torque reduction value, as it can vary depending on the materials involved.
Lastly, it is important to note that anti-seize lubricants should not be used in certain applications. For example, do not use them on damaged or cross-threaded fasteners, caliper slide pins, threads for a bushing press, or any mechanical assembly that requires a lubricant. Additionally, avoid using anti-seize lubricants on exposed threads, as they can attract contaminants that may contribute to thread damage during fastener removal.

Secure the rivet with adequate pressure
To secure a rivet with adequate pressure, you must first determine the type of rivet you are working with. There are three main types: pop rivets, blind rivets, and solid rivets. Pop rivets have a stem that breaks off, while blind rivets are inserted from one side of the material and remain hidden. Solid rivets require a hole to be drilled into both materials being joined. Once you've identified the type of rivet, you can proceed with the appropriate repair method.
If you are dealing with pop rivets, you will need to drill out the old rivet and replace it with a new one. Use an electric drill with a bit that is slightly larger than the diameter of the rivet stem. After drilling, insert the new pop rivet into the hole and use a hammer or another tool to flatten the stem. For blind rivets, you can insert a new rivet from one side of the material without needing to drill. As for solid rivets, you will need to drill holes into both materials and then insert the new rivet.
When installing a new rivet, it is crucial to apply adequate pressure to secure it in place. One method is to use a hammer to apply firm and controlled strikes directly on the rivet head. It is recommended to place a piece of metal or wood over the rivet to distribute the force evenly and prevent direct pressure on the rivet itself. This helps avoid damage to the rivet and ensures that the force is transferred to the surrounding material, creating a secure hold.
Additionally, when securing the rivet, it is important to consider the surrounding material. If the material around the rivet is damaged or weakened, you may need to cut or drill out a larger hole to accommodate a new and larger fastener. This ensures that the rivet has a strong and stable foundation to provide an effective hold.
