How to Choose the Right Sealey Individual Socket
Match the fastener profile, drive size, depth and intended tool before choosing an individual socket or socket bit.
Four details identify most sockets
Start with the fastener, then match the drive and reach you need. Do not choose on nominal size alone.
Match the fastener profile
Choose the correct hex, TRX-Star, spline or specialist profile to minimise fastener damage.
Match the square drive
Use the drive size that suits your ratchet, bar or torque tool and the level of access available.
Choose the depth
Deep sockets reach recessed fasteners or longer studs; standard sockets are often more compact.
Hand or impact use
Only use sockets specifically rated for impact tools when using an impact wrench.
A socket is more than just a size
A correct nominal size is only one part of the choice. The fastener profile, square drive, socket depth and intended use all need to match the job and the tool driving it.
Information to check before ordering
- Fastener size
- Fastener profile
- Square drive size
- Standard or deep reach
- Clearance around the fastener
- Whether the socket will be used by hand or with an impact tool
Avoid the expensive shortcut
Similar-looking products are not automatically interchangeable. Use the product reference and application information together rather than selecting from appearance alone.
Choose by the job, not just the product name
These broad groups explain the main differences to think about before you jump into the product directory.
Socket bits
Combine a socket drive with a shaped bit for internal fasteners such as TRX-Star and other specialist profiles.
Standard sockets
Compact and suitable for many general fasteners where the nut or bolt head is readily accessible.
Deep & specialist sockets
Useful for recessed fasteners, protruding studs or vehicle-specific access where additional reach is required.

Quick answers before you choose
Can I use a 3/8-inch socket on a 1/2-inch ratchet?
Not directly. The square drive must match, unless a suitable adaptor is used and the adaptor is appropriate for the load.
When should I choose a deep socket?
Use a deep socket where a stud protrudes through the nut or the fastener sits too deep for a standard socket.
Why is the fastener profile important?
Using the correct profile improves contact with the fastener and reduces the risk of rounding or damaging it.
