Some days ago, I went to the market with my friends to buy a broadhead for hunting purposes. I asked the boy in the shop to give me a broadhead.
He asked me what the size of your arrow shaft is and what thread size of broadhead you want. Please tell me. As beginners, first, we wondered about and asked what the need of thread size of broadhead.
Broadhead Thread Size
The thread size of the broadhead is very crucial for hunting in archery. It ensures compatibility with your arrow shaft and inserts. As a result, it provides a secure attachment and reduces wobble during flight. Therefore, it offers an improved accuracy shot during hunting.
Wait, there is more to share! If you are interested in knowing about the thread size of broadhead in detail and how to determine it, Follow along then!

Key Point
What’s The Need Of Thread Size Of Broadhead?
Well, thread size of broadheads plays a crucial role in hunting archery. Because it determines how the arrow shaft is attached to the broadhead. Here is the importance of the thread size of the broadhead:
Integrity
In archery, different broadheads, and arrow shafts have varying thread sizes. The arrow shafts and broadhead need to be fit together correctly.
For this reason, The arrow shaft and broadhead require matching thread sizes. If the thread size is a mismatch, the arrow shaft will not screw properly with the broadhead. This leads to loose fittings and potential detachment. So, ensure that the thread size matches every type of broadhead.
Safety
A proper size thread ensures the proper attachment between the arrow shaft and broadhead. This is very important for safety when shooting or hunting activities are done. A loose attachment can affect accuracy and arrow flight. These can lead to accidents. So, you should be careful about the proper attachment of the broadhead and arrow shaft.
Damage prevention
The correct thread size of the broadhead helps to prevent damage to both the arrow shaft and broadhead. The incorrect thread size of the broadhead causes cross-threading or stripping. This leads to permanent damage to the equipment. Mismatched thread sizes can cause damage to both the broadhead and the arrow shaft.
Consistency
The correct thread size across your arrow shaft and broadhead will improve consistency in shooting. Consistency is the most important in hunting and archery. A properly fitted broadhead promotes consistent arrow flight and accuracy. Using the correct thread size helps to maintain the integrity. As a result, shooting performance may improve.
Installation
When the thread size matches the broadhead and arrow shaft, it is easy to install. It saves time and hassle. But when it does not match with the broadhead and arrow shaft, then it is very difficult to install. It kills time. So, You should select the correct broadhead thread size to save time and for easy installation.
Are All Broadhead Threads Size The Same?
All broadhead thread sizes are not the same. Broadhead threads can differ based on the manufacturer and design. For intense The industry standard broadhead thread size is 8/32. This can be applied to all arrow broadheads except deep six thread size broadheads. This thread size can easily screw in various broadheads.
In general, the 8/32 thread size is the standard for inserts’ inside diameter. And the sevr broadhead comes in two sizes such as 8 to 32 and deep-six.
Therefore,
When buying arrow components, you should pay more attention to the insert’s outside diameter to match the various shaft sizes available on the market rather than worrying about thread sizes. Kudu broadheads are also commonly used with two sizes.
Things That Influence The Thread Size Of Broadhead
Many things greatly influence the size of the broadhead. Here are several things that affect the thread size of the broadhead are described below:
- Arrow shaft Diameter: Different arrow shafts have different diameters. The thread size of the broadhead must match the arrow shafts. The common diameter shafts are 5/16, 11/32, and 9/32 inch.
- Arrow Weight and Spine: Broadhead performance is influenced by the weight and stiffness of your arrow. Arrows with a minimum spine of 400 should fall between 8.5 and 10.5-grain weights per inch when hunting big game. This gives broadhead drag enough force to effectively pierce.
- Arrow insert type: The insert used in the arrow shaft affects the thread size of broadheads. There are various types of inserts with different sizes and thread configurations, including hit insert, screw-in insert, etc. So, you have to select the correct insert for a broadhead with the proper thread size.
- Broadhead Design: There are various broadhead opinion designs, including mechanical, fixed blade, and hybrid broadhead. Different broadheads need different thread sizes to accommodate their specific mechanisms and construction.
- Compatibility with Arrow Components: The thread size should match the overall configuration of the arrow and its components. Broadheads must be compatible with the arrow shaft and with nocks, fletchings, and arrow rests.
- Industrial standards: The most common thread size is the industry standard 8-32 thread dimensions for broadheads. Trends can evolve.
Because of new technologies and manufacturing processes, there can be changes in thread size to optimize performance.
Thread Size Of Broadhead
Here is a table which is about the thread size of different types of extra broadheads:
Broadhead type | Thread size (in inches) |
2-Blade Fixed | 8-32, 10-32 |
3-Blade Fixed broadhead | 8-32, 10-32 |
Mechanical/Expandable | 8-32, 10-32, 11/32, 5/16 |
standard muzzy 3-blade broadhead’s thread size | 8-32 |
Traditional | 11/32, 5/16 |
Deep six broadheads | Deep six |
What If I Use The Wrong Size Thread In A Broadhead?
If you use the wrong size thread in a broadhead, you have to face different types of problems. Like,
- Incompatibility: If the broadhead does not attach perfectly to the arrow shaft, it will lead to instability during flight. It will also lead to detachment upon release. This results in inaccurate shots.
- Equipment damage: The incorrect thread size of the broadhead causes cross-threading or stripping. This leads to permanent damage to the equipment.
- Safety risks: If the broadhead is not attached to the arrow shaft due to the mismatch of thread size. Broadhead may lose during shooting for this reason. A loose attachment can affect accuracy and arrow flight. These can lead to accidents.
- Ineffectiveness: If the broadhead is attached with the incorrect thread size, it might function differently when it hits something.
The alignment and cutting power of a broadhead can be impacted by improper attachment, which could result in less penetration and efficacy when used on game animals.
Advantages Or Disadvantages Of Using Broadheads With Larger Or Smaller Thread Sizes
Advantages of using broadheads with larger or smaller thread sizes:
Larger Thread Size | Smaller Thread Size |
Increased Cutting Surface | Reduced Drag |
Deeper Penetration | Less Risk of Over-Penetration |
Disadvantages of using broadheads with larger or smaller thread sizes:
Larger Thread Size | Smaller Thread Size |
Potential for Over-Penetration | Reduced Cutting Surface |
Increased Drag | Limited Cutting Power |
How To Determine The Right Size Of Thread For Broadhead?
I know all those sizing charts may have confused you. So, here are some steps to determine the right size thread for your broadhead:
Isn’t it clear? Let’s see an example:
Imagine you are using a broadhead with a threaded portion that is 8 to 32. So, your insert must be the same size, such as 8 to 32, so that the arrow shaft fits with the broadhead securely.
Now, it is time to install it. If you are a beginner, seek guidance from a skilled archer to install it properly. With the right size thread broadhead, you can hunt any types of game.
Frequently Asked Questions (FAQ’s)
What Is The Smallest Thread Size?
The smallest thread size is known as a miniature screw thread and it starts from 0.3mm in diameter.
What Size Thread Is A Bow Sight?
Bow sights typically use a standard thread size of 10-24, which refers to the diameter and threads per inch of the screw. This size is common across many archery accessories, allowing for compatibility and easy installation on most bows.
What Is The Normal Thread Size?
0.3, 0.4, 0.5, 0.6, 0.8, 1.0, and 1.2 mm are the preferred sizes; more chosen sizes fall in between. The standard thread pitch is about 14 of the main diameter.
Final Thoughts
In the end, what’s the need for the thread size of broadhead? It is very crucial to know about the thread size of the broadhead. A right-sized thread helps to attach securely to the arrow shafts.
It helps to provide you with an increased cutting surface and deep penetration of the target. If it is not compatible with your arrow shaft and inserts, it may cause abnormal behavior of the arrow during flight. I think you have a clear vision of it, and that’s all for today!
