When it comes to sockets, one of the most common questions asked is whether you should get a 6 point or 12 point socket set. The choice between 6 point and 12 point sockets depends on a few key factors that are important to consider before deciding which set is right for your needs.

What is the Difference Between 6 Point and 12 Point Sockets?
The main difference between 6 point and 12 point sockets is the number of splines inside the socket. Splines are the protruding ridges that fit into the grooves on bolt heads and nuts:
- 6 point sockets have 6 splines arranged in a hexagonal pattern.
- 12 point sockets have 12 splines arranged in a double hex pattern.
With more splines, 12 point sockets grip bolt heads and nuts more securely than 6 point sockets. However, the tradeoff is that with more contact points, 12 point sockets are more prone to rounding off bolt heads if used improperly.
When to Use 6 Point Sockets
Here are situations when 6 point sockets are recommended over 12 point:
- Damaged fasteners – The hex shaped gripping pattern applies more torque force, making 6 point sockets less likely to round off damaged bolt heads or nuts.
- High torque applications – The 60 degree angle between splines enables 6 point sockets to better handle high torque without slipping or wearing prematurely.
- Precision fittings – The tighter tolerances of 6 point sockets make them preferable for precision applications like automotive fittings.
When to Use 12 Point Sockets
Here are situations where 12 point sockets excel over 6 point:
- Speed – Because you can engage the fastener from more angles, 12 point sockets allow you to remove and install hardware faster.
- Accessibility – The ability to engage from multiple angles makes 12 point sockets ideal for tight spaces and awkward angles.
- Rusty hardware – The greater number of splines provide better grip and torque on rusty or stripped fasteners.

6 Point vs 12 Point Sockets: Drive Size
Socket drive size is another factor to consider when choosing between 6 point and 12 point sockets. The most common drive sizes are 3/8″ and 1/2″. Here are some guidelines on which to use:
- 3/8″ drive sockets are best suited for light duty tasks, smaller fasteners, and home DIY use. They provide adequate torque while being lighter and easier to handle.
- 1/2″ drive sockets are designed for heavy duty tasks, larger fasteners, and professional use. They can handle significantly higher torque levels without damage.
- For a well rounded home toolkit, a mixed set with both 3/8″ and 1/2″ drive sockets can cover all common fastening needs.
Typically, ratchets come with quick release levers that allow switching between 3/8″ and 1/2″ drives. This makes mixed socket sets very convenient for both small and large jobs.
6 vs 12 Point Socket Sets
When purchasing sockets, you can buy them individually or in pre-packaged sets. Here are some things to consider when looking at socket set options:
- Some sets are available in just 6 point, just 12 point, or a mix of both. Choose based on your most common needs.
- Larger sets will provide a wider range of metric and SAE socket sizes for full fastener coverage.
- Buy quality brand name sockets. Cheap sockets are prone to rounding and fracture under high torque.
- Ensure the set has the drive sizes you require. A combined 3/8″ and 1/2″ set offers the most flexibility.
- Look for storage options like a case or rails to keep the sockets organized.
When in doubt, start with a middle size mixed set with both 6 point and 12 point sockets in the most common 3/8″ and 1/2″ drive sizes. This will cover you for most household tasks.
6 Point vs 12 Point Impact Sockets
Impact wrenches and drivers apply extreme torque for tasks like loosening rusted bolts. This requires impact rated sockets designed to withstand the forces.
- For impact use, 6 point sockets are generally preferred for their greater resistance to rounding and fracture.
- 12 point impact sockets also exist, but tend to be alloy reinforced for added durability under impulse torque.
- Avoid using chrome plated sockets with impact tools. The chrome is prone to crack and peel under impact.
When using high torque impact tools, invest in quality 6 point impact sockets made of heat treated alloy steel. These will provide the best grip and longevity under extreme loads.
Conclusions
Deciding between 6 point and 12 point sockets comes down to considering your usage needs:
- For heavy duty tasks and impact use, go with 6 point sockets.
- For speed, accessibility and seized fasteners, choose 12 point sockets.
- For maximum versatility, choose a mixed set with both 6 point and 12 point sockets.
- Match the drive size to the job, with 3/8″ for light duty and 1/2″ for heavy duty tasks.
- Buy quality brand name sockets made of durable chrome vanadium steel.
With the right socket set and matching your sockets to the job, you’ll be equipped to tackle automotive repairs, construction projects, and home DIY tasks. Investing in a versatile mixed 6 point and 12 point socket set will provide you with the right tool for any fastening needs.
