Golf ferrules are the small black pieces, usually made of plastic, that connect the shaft of a golf club to the hosel. They are primarily decorative, but they also provide a smooth transition from the shaft to the hosel, hiding the sharp edges of the hosel where the shaft enters the clubhead. When selecting a ferrule, it is important to consider the length and diameter of the hosel and shaft. The length of the ferrule should be proportional to the length of the hosel, and the outside diameter of the ferrule should not be smaller than the hosel. Additionally, the inside diameter of the ferrule must accommodate the shaft tip.

The ferrule's length should be proportional to the hosel's length
The ferrule is the black piece of plastic located just above the club head's hosel. It is primarily a decorative element, but it also provides a smooth transition from the shaft to the hosel, covering the sharp edges of the hosel where the shaft enters the clubhead.
When selecting the length of the ferrule, it should be proportional to the length of the hosel. A shorter ferrule looks better on a short hosel, and a longer ferrule looks better on a longer hosel. This is because the ferrule is intended to provide a smooth transition from the top of the hosel into the shaft, so its length should match the hosel's length.
The outside diameter of the ferrule is also important. In the past, the outside diameter of the ferrule was typically larger than the average hosel, so clubmakers would have to sand or "turn down" the ferrule to achieve a smooth transition. However, this takes up valuable time, and many clubmakers do not have the right equipment. Therefore, it is now considered best practice to select a ferrule with an appropriate outside diameter that matches the hosel. This ensures a seamless fit without the need for additional sanding or adjustments.
It is worth noting that ferrules are not always required, especially on steel shafts, where they serve a purely cosmetic purpose. However, on graphite shafts, ferrules add structural integrity and are, therefore, necessary. When re-shafting a golf club, the ferrule will likely be destroyed and will need to be replaced.

The outside diameter of the ferrule should not be smaller than the hosel
The ferrule is a small piece of plastic that sits just above the club head's hosel, connecting the shaft of the golf club to the hosel. It is primarily a decorative element, but it also serves a functional purpose by providing a smooth transition from the shaft to the hosel. The outside diameter (OD) of the ferrule is an important consideration when determining ferrule size for golf clubs.
The outside diameter of the ferrule should ideally match the outside diameter of the hosel where the ferrule will sit. This creates a seamless transition with no lip or edge. However, it is not always possible to find a ferrule with a perfect OD match. Therefore, it is recommended to choose a ferrule with an OD that is slightly larger than the hosel's OD. This allows for a custom and professional look after turning down the ferrule by sanding or grinding it to become flush with the hosel metal.
While selecting a ferrule with a slightly larger OD is a common practice, it is important to ensure that the ferrule is not significantly larger than the hosel. In such cases, more extensive sanding or grinding may be required during the installation process. Additionally, it is worth noting that the hosels of clubheads can vary in size, so knowing these dimensions beforehand can save time and effort in finding the right ferrule.
To ensure a precise fit, it is advisable to measure the outside diameter of the hosel using digital calipers. By obtaining accurate measurements, golfers can select a ferrule with an OD that is slightly larger, knowing that it can be adjusted to achieve a perfect fit. This attention to detail can enhance the overall appearance and functionality of the golf club.

The inside diameter of the ferrule should match the shaft tip
The ferrule is the small black piece of plastic that connects the shaft of a golf club to the hosel. Its primary function is decorative, providing a smooth transition from the shaft to the hosel. However, it also serves a practical purpose by covering the sharp edges of the hosel where the shaft enters the clubhead.
When selecting a ferrule, it is important to ensure that its inside diameter matches the shaft tip. Ferrules are manufactured with different inside diameters to accommodate various shaft tips. Therefore, it is crucial to measure the diameter of the shaft at the point where the ferrule will sit. This measurement will help you choose a ferrule with the appropriate inside diameter.
It is worth noting that the outside diameter of the ferrule is also important. While it should not be smaller than the hosel, it is preferable to have a slightly larger outside diameter. This allows for a smooth fit and avoids any unsightly gaps between the ferrule and the hosel.
Additionally, the length of the ferrule should be considered. A shorter ferrule complements a short hosel, while a longer ferrule suits a longer hosel. Re-shafting a golf club will likely damage the ferrule, so it is important to select the right length initially.
By paying attention to the inside and outside diameters, as well as the length of the ferrule, you can ensure a proper fit and enhance the appearance and functionality of your golf club.

The clubhead design may require a specific ferrule
There are two main types of ferrules: standard and repair. Repair ferrules are specialty ferrules for specific clubhead designs, usually from large OEM manufacturers. They can act as hosel reducers to allow a smaller diameter shaft to fit inside a slightly larger hosel diameter. For example, many OEM manufacturers have 0.350" hosels, but there are fewer .350" shafts available. A special ferrule can reduce the hosel opening to 0.335", allowing for more shaft models to be used. This practice will not compromise the shaft if properly installed.
Some clubheads are designed with a beveled or tapered hosel and are not intended to be used with a ferrule. For example, the Ping iron heads have a hosel that tapers slightly at the top. On the other hand, if the top of the hosel of the clubhead is flat or square, it is intended to have a ferrule installed. Almost all clubheads are designed this way today.
When selecting a ferrule, it is important to consider the length and diameter of the ferrule and hosel. The length of the ferrule should be proportional to the length of the hosel. A shorter ferrule looks better on a short hosel, while a longer ferrule suits a longer hosel. Additionally, the outside diameter of the ferrule should not be smaller than the hosel. Knowing the dimensions of the hosel can help ensure the correct size ferrule is ordered, saving time and effort in the club-making process.

Collared ferrules are optional and provide added protection
The ferrule is a small, usually black, plastic piece that connects the shaft of a golf club to the hosel. It is mostly a decorative element, but it also provides a smooth transition from the shaft to the hosel, covering up the sharp edges of the hosel where the shaft enters the clubhead. While ferrules are typically used for cosmetic purposes, there is a special type of ferrule called a "collared ferrule" that provides added protection.
Collared ferrules are a more recent development in the golf world. They have a flange below the ferrule itself that fits into the countersunk portion of the hosel, reducing the stress on the shaft. This type of ferrule is commonly used with graphite shafts, as graphite can be fragile and depend on the strain put on it. Collared ferrules allow for a cushioning layer of epoxy between the shaft and the ferrule, which helps protect the shaft from stress and potential failure.
While collared ferrules provide added protection, they are not required for all golf clubs. In fact, some clubs are made without any ferrules at all. For example, wooden-shafted drivers and other woods typically used "whipping" instead of ferrules, where a strong thread was wrapped around the hosel area. Additionally, some club heads, such as Ping iron heads, have a beveled hosel that is not intended to be used with a ferrule.
When selecting a ferrule, it is important to consider the length and diameter of the hosel. The length of the ferrule should be proportional to the length of the hosel, with shorter ferrules better suited for short hosels and longer ferrules for longer hosels. Additionally, the inside and outside diameters of ferrules can vary, so it is important to ensure that the ferrule will fit properly with the shaft and hosel.
Overall, collared ferrules are optional and can provide added protection for certain types of golf clubs, such as those with graphite shafts. However, it is important to consider the specific design and dimensions of the club head and shaft when determining the appropriate type and size of ferrule.

Frequently asked questions
The golf ferrule is the black piece located just above the club head's hosel. It provides a smooth transition from the top of the hosel into the shaft.
Ferrules can be grouped into two categories: standard and repair ferrules. Collared ferrules are a more recent development and are precision-manufactured pieces. They fit between the clubhead and the shaft with a collar that creates space for a cushion of epoxy. Uncollared ferrules, on the other hand, sit flush on the neck of the club.
The ferrule size depends on the dimensions of the hosel and the shaft. The length of the ferrule should be proportional to the length of the hosel. The outside diameter of the ferrule should not be smaller than the hosel. Additionally, measure the diameter of the shaft at the point where the ferrule will sit.
