Impact Wrench: Hog Ring vs Detent Pin

Depending on the design of an impact wrench, you will find that one either has a hog ring or a detent pin. These two are crucial for holding the socket to the driver. However, you would want to know what is the difference between the two before picking a power tool.

A hog ring is designed to work like a snap ring fitted around the square socket drive groove. The work of the hog ring is to hold the adapter or the socket onto the driver.

The detent pin features a spring-loaded ball bearing in the square groove to hold the socket onto the driver. As you can see, both do the same function only through different mechanisms.

Best Impact Wrenches with a Hog Ring or Detent Pin

Now that you know the difference between the two, it is best we looked at some of the common products having the two mechanisms. Below are the two examples.

Best Impact Wrench with Hog Ring:

DeWalt DCF899HB 20V Max XR Impact Wrench with Hog Ring Anvil

DEWALT (DCF899HB) 20V MAX XR Impact Wrench Kit, Brushless, High Torque, Hog Ring Anvil, 1/2-Inch, Tool Only

Being one of the top impact wrenches in the market, the DCF899HB stands out for its brushless motor. The motor design is aimed at making it work better without overheating and requires less to no maintenance to keep the wrench working better. Also, the motor is energy efficient, meaning you will not keep on recharging it all the time to work on a project.

We also have to look at the amount of torque you get with the unit. The maximum torque is 700 feet/pound. The breakaway torque is 1,200 feet/pound. With such amazing figures, it should be easy to see why it would be ideal to own this type of impact wrench.

As for the speed settings, you will get up to 3 modes to choose from when using the wrench. The modes include 400, 1200, and 1900 RPM.

If you accidentally drop it, the unit is tough so it might not break in comparison to other units. With a 6ft drop, you can simply pick it up and continue working.

Best Impact Wrench with Detent Pin:

DeWalt DCF889M2 20V Max Impact Wrench Kit Detent Pin Anvil

DEWALT 20V MAX Impact Wrench Kit, High Torque, Detent Pin Anvil, 1/2-Inch (DCF889M2)

The Detent pin is a different mechanism that you get with the other DeWalt model mentioned above. As a result, you might experience some differences in performance.

Looking at its lithium ion battery, it is able to deliver enough energy for you to work on various projects. The fast charger that comes with the unit allows for quickly recharging the battery to get back to work.

As for the torque, you can expect a maximum of 400 ft-lbs. With such torque, it should be enough to get you the best performance you might need to handle various applications.

To boost the torque, we find the unit using the best batteries. Since the battery has a fuel gauge, you would know how much power is remaining while working on different projects.

The presence of a variable speed trigger makes the unit ideal for many uses. You simply have to choose the speed depending on applications. The electric brake is also a nice feature that helps with improving the overall control of the impact wrench.

We cannot forget to mention the LED lights that come with the unit. Such lights can be great for those who might end up working in poorly lit areas.

The durable magnesium gear case and the metal transmission all ensure there is extended durability with this unit. You should find it versatile for working with different materials without much of a problem.

Impact Wrench Buyers Guide – Everything You Need To Know

The Type of Motor

The motor technology in impact wrenches has improved over the years. As such, it is important to know the type of motor that your impact wrench is using. We would recommend that you go for a brushless motor.

This type of motor is ideal for those who might want a unit that delivers better power output, saves on battery use, and does not need a lot of maintenance to keep the impact wrench working.

Its Torque

The amount of torque varies a lot from one model to another. Some might have a high torque output while others will be average. Each manufacturer proudly displays the torque values.

It is from these values that you can know which model will be ideal for which applications. For someone that works on tough applications, then having a unit with high torque is important.

Someone who only works on DIY applications at home, then a model with average torque should be enough.

High RPM

The speed determines how fast you can accomplish some tasks. The more rotations you get per minute, the easier it will be for you to complete the task. You should never skimp on the amount of speed you get with an impact wrench.

Depending on the unit, most would go over 2500 RPM. This is a good speed to allow for quick fastening and loosening of bolts and screws. Consider opting for an impact wrench containing multiple speed settings.

Such settings allow you to choose the right speed to handle the different tasks. Some tasks might need you to drive the impact wrench at slower speeds and vice versa. It is good to know that you can get such versatility.

High Impacts Per Minute

It is common for people to confuse between impacts per minute and revolutions per minute. The IPM is a crucial measurement of the performance of your impact wrench. The higher this value the better.

Having a high rating of the impacts per minute means that the impact wrench can accommodate a wide range of projects. You cannot afford to skimp on the IPM rating for your new impact wrench.

Type of Drive

The type of drive can be a critical factor to consider when buying an impact wrench. The common types include ¼, 3/8, and 1/2 – inch drives. The bigger the drive, the higher the torque you will get out of the unit.

So, depending on the type of work you do, get the model with the right drive. Heavy-duty applications need the user to have the ½-inch drive.

Weight and Size

The weight and size often determine the comfort of using the impact wrench over extended periods. In most cases, impact wrenches are designed to be lightweight.

This makes it easy for you to work on various projects for longer without straining your wrist and arm. As much as you would want a lightweight and compact model, make sure that it is also functional.

Any Safety Features

When dealing with power tools, it is important that you keep in mind the safety too. Look at what are some of the safety features that the manufacturer offers for you to consider before making up your mind.

Newer impact wrenches will have more safety features such as prevention of overloading, better cooling, no over-discharging, and much more. Any manufacturer would proudly list their safety features to attract more buyers.

Battery Performance

The overall battery performance is important to see how long it would last before you have to recharge it again. The battery performance varies from one brand to another.

Most will however be lithium-ion batteries. Such batteries are good for delivering steady power and can hold more charge.

More manufacturers are now selling their batteries with fast charging capabilities. This allows you to recharge the battery faster and continue with work.

Reading several reviews about the model’s battery performance can help you learn more about what to expect.

LED Lights

It seems like new impact wrenches will have this feature. LED lights are important to illuminate your working area so that you can see better. For those working in poorly lit areas, having the extra light ensures you do not make mistakes.

The LED lights might not be available on all models, but it is a nice feature to have on a new impact wrench.


Both hog rings and detent pins do the same job, however, most would prefer a hog ring rings in cases where they need a tighter fit. Also, depending on how often you replace the sockets, either can be ideal.

Take your time to also look at what the power tool has to offer, whether it uses a hog ring or detent pin. Do not let one part of the impact wrench determine which model you choose.
