Product Information
Full details
The Laser 0817 21mm single hex socket is designed for professional mechanics, automotive technicians, and dedicated DIY enthusiasts who require a robust and precise tool for fastening applications. Its primary benefit is its heavy-duty chrome vanadium construction, which provides exceptional torque resistance and long-term durability in high-pressure workshop environments. A key caveat to keep in mind is that as a standard single hex socket, it is specifically sized for 21mm fasteners and is not intended for use with impact drivers that require specialized impact-rated steel.

FAQs
Can I use this socket with an impact wrench?
No, this socket is designed for hand tools only. Impact tools require impact-rated (usually black oxide/chrome molybdenum) sockets to prevent potential shattering.
What is the material used for this socket?
The Laser 0817 is manufactured from durable chrome vanadium steel.
Is this a 6-point or 12-point socket?
This is a single hex (6-point) socket, providing superior grip and reducing the risk of rounding bolt heads.
Will this fit a 3/8-inch drive ratchet?
No, this socket is specifically designed for 1/2-inch square drives. You would need a 1/2-inch to 3/8-inch adapter to use it with a smaller drive tool.
How do I prevent the socket from rusting?
Keep the socket clean and dry. A light coating of mineral oil or tool oil after wiping it down will help protect the chrome finish from environmental moisture.
Troubleshooting
Socket feels loose on the ratchet head
Ensure the detent ball on your 1/2-inch ratchet is functioning correctly and is fully engaged with the retention hole on the socket.
Socket will not fit over the fastener
Verify the bolt head is exactly 21mm and not damaged or covered in thick layers of rust, paint, or road grime.

Setup, Compatibility & Care
To ensure the longevity of your Laser socket, always ensure that the 1/2-inch drive square on your ratchet is clean and free of debris before attaching the tool. This socket is designed strictly for hand-tool applications; avoid using it with power-driven impact tools to prevent premature fatigue of the metal. For maintenance, wipe the socket with a light machine oil after use to displace any moisture, especially if used in a humid or unheated garage environment. Store the tool in a dry toolbox or on a socket rail to prevent surface oxidation.
