TIMCO impact sockets in the X6 range are made for the kind of work where a standard chrome socket would either slip, crack, or simply give up. Hardened and tempered steel, a phosphate finish to keep rust at bay, and a 78mm deep profile that gives you reach where you need it. If you’re running an air impact wrench or a cordless impact driver, these are the sockets to pair with them.
The range covers sizes from 8mm through to 24mm, so whether you’re torquing down structural bolts, working on plant machinery, or stripping out automotive fixings on site, there’s a size that fits. The 78mm length is worth noting: it’s not the shortest socket on the market, which is the point. That extra depth means you can seat fully on recessed or proud fixings without wobbling around and rounding edges.
Where TIMCO X6 Impact Sockets Earn Their Keep
Impact sockets are not the same as standard drive sockets. Standard sockets are made to be turned by hand or with a ratchet, where the torque builds gradually. Impact drivers and air wrenches deliver sudden, hard rotational strikes, and a socket that isn’t rated for that kind of load will eventually crack or shatter. The TIMCO X6 sockets are hardened and tempered specifically to absorb that shock loading without failing.
The phosphate finish does two things: it adds a layer of corrosion resistance for sockets left in a van or stored in a site box, and it reduces surface shine, which matters less on a socket than on a display piece but still signals a working finish rather than a decorative one.
Steel Quality and Finish
High grade steel with hardening and tempering throughout means these sockets won’t just hold up on first use. They’re built to be picked up, thrown in a bag, and used again tomorrow. The phosphate coating is a practical trade finish, not a chrome plating that chips off the moment you drop them on concrete.
At under a fiver per socket, TIMCO impact sockets make sense as a working set rather than a Sunday-best tool collection. Stock the sizes you use daily and keep a couple of the larger ones on standby for when the unexpected bolt turns up.
Pro Tip: Always use a ball-retaining pin or a socket retainer ring with impact sockets on air wrenches: the vibration from repeated strikes can work a socket loose mid-fastening, and a flying 19mm socket is nobody's idea of a good day.
These sockets are at home on construction sites, agricultural machinery, plant hire, automotive work, and anywhere that involves high-torque fastening or removal. They work equally well driven by a 1/2 inch cordless impact driver or a pneumatic air wrench. Structural steelwork, heavy plant servicing, scaffold assembly, groundworks equipment, and vehicle maintenance are all typical territory for a set like this.

Suitable for impact use
Not suitable for: Not suitable for use with standard ratchet handles as a long-term substitute, though they will fit. These are rated for impact use, not designed to replace chrome vanadium hand tool sockets for fine torque work.
Select the correct size socket for your fastening and attach firmly to the 1/2 inch drive on your impact wrench or impact driver. Seat the socket fully onto the bolt or nut head before applying power. Use a retainer pin or ring if working overhead or in a position where a dropped socket would be a problem.
For removal of seized or corroded fasteners, a short burst of penetrating fluid applied beforehand will do more for you than extra torque. Let the impact action do the work rather than holding the trigger flat out from the start.
Select the correct socket size for the fastener you are working on
Attach the socket securely to the 1/2 inch square drive on your impact wrench or driver
Fit a retainer pin or ring if working at height or in a confined space
Seat the socket fully and squarely onto the bolt or nut head before activating
Use short controlled bursts rather than sustained full power on stubborn fixings
Apply penetrating fluid to seized fasteners before attempting removal
Can I use these TIMCO impact sockets with a standard ratchet handle?
Technically yes, they will fit a 1/2 inch ratchet. But impact sockets are made from tougher, slightly more brittle steel than chrome vanadium hand tool sockets, so there is no real benefit to using them by hand. Use your chrome vanadium sockets for ratchet work and keep these for the impact driver or air wrench.
What does the phosphate finish actually do on these sockets?
It adds a layer of corrosion resistance, which is useful if the sockets are going to live in a toolbox or van rather than a climate-controlled workshop. It also gives a better grip surface compared to polished chrome, which is a minor but practical point when you are handling them with oily or gloved hands.
TIMCO X6 impact sockets are manufactured from high grade steel that has been hardened and tempered to withstand the shock loading produced by air impact wrenches and cordless impact drivers. The phosphate surface finish provides corrosion resistance in site and workshop conditions. All sizes share a consistent 78mm length and a standard 1/2 inch square drive connection.
