A 31mm axle nut socket needs to fit the fastener and your tool’s drive size; the products below use a 1/2-inch drive. EGOFIX is a focused choice for buyers who need one deep socket, while BUYROBUS and DAYUAN offer multiple metric sizes for broader work. ELEAD adds an 11-size range and an adapter, and TEKTON is a single-size option with two forms of size marking.
| Product | Best For | What Stands Out |
|---|---|---|
| EGOFIX 31mm | One-size axle-nut jobs | CR-MO, deep, 6-point design |
| BUYROBUS 9-Piece | Common large metric sizes | 29–38mm range |
| ELEAD 11-Piece | Broader size coverage | 27–38mm selection and adapter |
| DAYUAN 9-Piece | Multi-size axle and hub work | Retaining-ball head holes |
| TEKTON 31mm | Readable size identification | Laser and stamped markings |
EGOFIX 31mm Deep Impact Socket
The EGOFIX is a dedicated 31mm, 1/2-inch-drive deep impact socket. Its six-point opening is designed to contact the fastener’s flats, which can help reduce corner damage when the socket fits properly. The manufacturer lists chrome-molybdenum steel construction, a black phosphoric acid coating, and laser-etched size markings.
Best for: Buyers who have confirmed they need a 31mm socket and do not need a set of neighboring sizes. Its deep profile and impact-socket construction make it a targeted option for axle-nut and garage work.
Consider: It includes only one size. Confirm the required socket depth and tool drive before buying.
BUYROBUS 9-Piece Metric Set
This set contains nine deep, 1/2-inch-drive impact sockets: 29, 30, 31, 32, 33, 34, 35, 36, and 38mm. The sockets are described as heat-treated chrome-molybdenum steel with a black phosphate coating. A six-point radiused interior is intended to improve contact with fastener flats, while dual-sided detent holes and an attachment groove help secure the sockets to compatible tools.
Best for: Home mechanics or shops that need 31mm plus nearby large metric sizes. Choose this set over a single socket if the correct size may vary between jobs.
Consider: It does not include 27mm or 37mm. Check the vehicle’s specified size rather than assuming the 31mm socket will fit.
ELEAD 11-Piece Axle Nut Set
ELEAD’s set includes 27, 29, 30, 31, 32, 33, 34, 35, 36, and 38mm sockets, plus a 3/4-to-1/2-inch adapter. The listed construction is chrome-molybdenum steel with a black phosphate finish. Its six-point openings are designed to grip fastener flats for high-torque tasks, and the size markings are laser-etched.
Best for: Buyers looking for a wider selection than a basic 29–38mm set and who may need the included drive adapter. It covers 31mm along with several other sizes for axle, spindle, or locknut work.
Consider: The listed sizes skip 28mm and 37mm. The adapter does not change the socket’s 1/2-inch drive connection at the tool end without checking the specific setup.
DAYUAN 9-Piece Hub Nut Set
The DAYUAN set includes 29, 30, 31, 32, 33, 34, 35, 36, and 38mm sockets for a 1/2-inch-drive impact tool. The product description specifies heat-treated 40 chrome steel and says each socket has a drilled head to locate a retaining ball on many breaker bars and impact wrenches. That feature may help provide a secure connection where the tool uses a retaining ball.
Best for: Buyers who want several axle-hub sizes and value the drilled-head retention feature described by the manufacturer.
Consider: The set omits 27mm and 37mm. Check that the retaining feature and socket dimensions suit your tool and access needs.
TEKTON 31mm Impact Socket
TEKTON’s single 31mm socket has a 1/2-inch drive and a six-point opening. Its size appears as both a high-visibility laser marking and a permanent stamped marking. The product also has a full-length interior socket well despite its shallow overall length, and it is designed to work with friction-ring or detent-pin anvils.
Best for: Buyers who want one 31mm socket with two types of size marking and a stated shallow exterior profile.
Consider: The shallow overall length may not provide the reach needed for every axle-nut setup. Check clearance and required engagement before choosing it over a deep socket.
Buying Guide: How to Choose a 31mm Axle Nut Socket
Do you need one socket or a set?
Choose a single 31mm socket if you have verified the fastener size and expect to use that size. A set is more practical when working on multiple vehicles or jobs with different nut sizes. Compare the included sizes carefully: the BUYROBUS and DAYUAN sets begin at 29mm, while ELEAD includes 27mm.
Does drive size matter?
All five options described here use a 1/2-inch drive. Match that connection to your impact wrench, breaker bar, or other tool. An adapter can alter the connection between a tool and socket, but it may add length; use one only when the setup is appropriate for the task.
Should you choose deep or shallow?
Deep sockets are commonly selected when the fastener or surrounding hardware requires additional reach. TEKTON describes its socket as shallow overall but with a full-length interior well. Check the actual space around the axle nut and the needed fastener engagement instead of relying on the product name alone.
What socket design and material should you compare?
A six-point opening is intended to engage the flats of a hex fastener. Several options list CR-MO construction and a black coating; DAYUAN lists heat-treated 40 chrome steel. Use impact-rated sockets with impact tools, and seat the socket fully before applying force. Follow the vehicle manufacturer’s service procedure for removal and installation.
Frequently Asked Questions
What size drive do these 31mm axle nut sockets use?
The five products reviewed here are listed with a 1/2-inch drive. Verify the socket and tool connection before use.
Is a 31mm socket the right size for every axle nut?
No. Axle-nut size varies by vehicle and application. Confirm the required size in the vehicle service information or by carefully checking the fastener.
Is a six-point socket suitable for axle nuts?
A six-point socket is designed to contact the flats of a hex fastener. Correct sizing and full engagement are important to reduce the chance of slipping or damaging the nut.
Can I use a regular socket with an impact wrench?
Use a socket specifically identified as impact-rated with an impact wrench. The products in this comparison are described as impact sockets or impact sets.
Which option is best if I only need 31mm?
EGOFIX and TEKTON are single-size choices. EGOFIX is listed as deep, while TEKTON is described as shallow overall; choose based on the reach your job requires.
