The size of the thread on a beer tap handle can vary depending on the specific requirements of the beer faucet. In the beer tap handle industry, there are generally two different sizes of hanger bolts that are commonly used – the 3/8″-16 size and the smaller 5/16″-18 size.
The larger size, 3/8″-16, is often used for displaying tap handles. This is because it matches the thread of a standard American beer faucet. These faucets typically have a 3/8″ diameter and 16 threads per inch. The 3/8″-16 hanger bolt is threaded on one end to match the faucet and has a wood screw on the other end for attaching the tap handle to the hanger bolt.
On the other hand, the smaller size, 5/16″-18, is less common but still used in some cases. This size is slightly smaller in diameter and has 18 threads per inch. While less standard than the 3/8″-16 size, some beer faucets may have this thread size, especially in older or specialty systems.
When it comes to choosing the right size of hanger bolt for a tap handle, it is essential to consider the specific beer faucet being used. If you are unsure of the thread size, it is recommended to consult with the manufacturer of the faucet or seek advice from a knowledgeable supplier in the industry.
In my personal experience as a sommelier and brewer, I have encountered both thread sizes while working with different beer taps and tap handles. It is always crucial to ensure a proper fit between the tap handle and faucet to prevent any loosening or instability.
To summarize, the size of the thread on a beer tap handle can vary, but the two most common sizes are 3/8″-16 and 5/16″-18. The larger 3/8″-16 size is typically used for displaying tap handles, matching the thread of a standard American beer faucet. The smaller 5/16″-18 size is less common but still found in some faucets. When selecting a hanger bolt for a tap handle, it is important to consider the specific thread size of the beer faucet being used to ensure a proper fit.
