1/2 Inch Drive x 1/2 Inch 12-Point Impact Socket
1/2 Inch Drive x 1/2 Inch 12-Point Impact Socket — Precise, Strong, and Built to Last
When your job demands torque, repeatability, and a perfect fit, the 1/2 Inch Drive x 1/2 Inch 12-Point Impact Socket is engineered to deliver. This impact-rated socket combines usability features—like high-visibility laser markings and a detent pin option—with mechanical design choices that extend fastener life and protect tool users.
Key Features at a Glance
- Dual markings: High-visibility laser marking plus a permanent stamped marking so size and specs remain readable even after heavy use.
- 12-point opening: Provides an exact fit on 12-point fasteners for increased contact area and easier alignment in tight spaces.
- Radiused corners: Designed to apply force to the flat sides of fasteners, not the corners—reducing the risk of round-off and extending fastener life.
- ANSI/ASME-rated strength: Meets a minimum of 1.3× the ANSI/ASME proof torque standard for added safety and durability under impact loads.
- Detent pin hole: One-sided detent pin hole gives you the option to lock the socket on a drive pin for secure engagement when needed.
- Size description: Clear size description is printed on the product for fast identification in busy toolboxes.

Why These Features Matter
Small design choices create big differences on the jobsite. The combination of a 12-point profile and radiused corners balances accessibility with protection: the 12-point interface makes it easier to line up on multi-sided fasteners in cramped areas, while the radiused corners distribute torque across the flats to reduce corner stress and round-off. That means fewer stripped bolts and smoother removal under heavy load.
Durability & Safety
Meeting at least 1.3 times the ANSI/ASME proof torque standard signals that the socket has been built and tested to exceed the baseline mechanical strength expected for professional impact tools. In practice, that added margin helps the socket survive repeated shock loads from impact wrenches without deforming or failing.
Usability
The dual marking system—laser for visibility and stamped for permanence—keeps the socket readable even after long exposure to grease and abrasion. The optional detent pin hole lets technicians decide whether to use a locking pin for secure retention on extensions or quick-release setups.
Applications & Compatibility
This socket is ideal for mechanics, heavy equipment technicians, and any tradesperson using impact tools on automotive, agricultural, or industrial fasteners. The 1/2" drive size is a standard for medium to heavy duty applications, making this socket compatible with most half-inch impact wrenches and breaker bars.
Pros & Cons
- Pros: Impact rated, high-visibility markings, reduced fastener damage, ANSI/ASME strength margin, detent pin option.
- Cons: 12-point sockets can have slightly less contact area than 6-point on very rounded fasteners—if you encounter a damaged bolt, switch to a 6-point impact socket.
Care & Maintenance Tips
- Wipe clean after use and store in a dry toolbox to reduce corrosion.
- Inspect radiused corners and markings periodically; replace any socket that shows visible cracking or deformation.
- Use the detent pin only when necessary—over-reliance can increase removal time in some setups.
Where to Buy
Look for sockets sold by reputable tool brands or authorized distributors. Compare warranty terms and manufacturing materials (for example, chrome molybdenum is typical for impact sockets) to ensure you get the combination of performance and longevity you need.
