1/2 Inch Drive 5-19mm Hex Impact Bit Socket

When a 17 mm hex fastener needs to come out — or go in — under serious torque, this is the tool that handles it. Designed with a 1/2 inch drive and built from CrMo material, it is purpose-built for the repeated hammering action of pneumatic and cordless impact wrenches.

The hex profile delivers full contact with the internal recess of the fastener, spreading the load evenly to reduce rounding and cam-out. That means fewer damaged bolts and less time chasing stripped heads with extraction tools. For technicians who work with metric hardware every day, dependable engagement is not optional — it is the difference between a clean job and a callback.

CrMo gives this tool the resilience to absorb thousands of impact cycles without cracking. Standard sockets are not designed for that kind of abuse, and using one on an impact wrench is a safety risk as well as a reliability problem. This socket is rated for impact use from the ground up.

The 1/2 inch square drive is the workhorse size for automotive repair, heavy equipment maintenance, and industrial assembly. It pairs with air tools and cordless platforms alike, so there is no need to change your workflow.

Sold individually, this 17 mm socket lets you buy exactly what you need. Replace a lost or worn piece, upgrade a single size to impact-rated quality, or build out your collection one socket at a time. Either way, you get a professional-grade tool without paying for sizes you already own.
