Impact sockets for commercial vehicle use
The difference between an impact socket and a standard chrome vanadium socket matters in a commercial vehicle workshop. Standard chrome sockets deliver torque smoothly and are manufactured to tight tolerances with a hard, brittle surface finish. Impact wrenches deliver torque through rapid hammer blows — this shock load causes chrome sockets to crack, shatter, or fail in ways that are hazardous to the user.
Impact sockets use a softer, tougher steel alloy that absorbs shock loads without cracking. The finish is typically matte black rather than chrome, and the wall thickness is greater. POWERHAND 1/2-inch and 3/4-inch drive impact sockets cover the sizes used daily in HGV workshops: 1/2-inch drive for general fastener work across the chassis and cab, 3/4-inch drive for wheel nuts and high-torque drivetrain work.
Torx impact sockets are essential as a dedicated set on Euro 5 and Euro 6 vehicles. Torx fasteners are common on cab components, fuel system hardware, and transmission covers. Standard Torx screwdriver bits are not rated for impact use.
Extension bars rated for impact use are a specific product — standard extension bars flex and can fail under impact loads. POWERHAND impact extension bars in 75mm, 200mm, and 250mm lengths cover the access requirements in HGV engine bays and chassis applications.

Frequently asked questions
Can I use standard chrome sockets with an air impact wrench?
No. Standard chrome vanadium sockets are not rated for impact use. The hard surface of a chrome socket can shatter under the shock loads produced by a pneumatic or electric impact wrench, creating a fragment hazard.
What drive size impact socket do I need for HGV wheel nuts?
HGV wheel nuts typically require a 33mm AF socket. For the drive size, 3/4-inch drive provides the torque capacity required for wheel nut work on heavy commercial vehicles.
What is an impact adaptor and when is it needed?
An impact adaptor converts between drive sizes when the available socket does not match the available wrench. The POWERHAND Impact Adaptor Set covers the common drive size conversions used in commercial vehicle workshops.
What Torx socket sizes are needed for HGV work?
The most common Torx sizes in HGV cab and component work are T40, T45, T50, T55, and T70. The POWERHAND 1/2-inch Torx Impact Socket set covering T30 to T80 provides comprehensive coverage.
