3-Piece Deep Impact Socket Set 17mm 19mm 21mm | 1/2" Drive

3-Piece CR-MO Deep Impact Socket Set – 17mm, 19mm & 21mm Wheel Nut Sockets

Keep your alloy wheels looking their best with this professional-grade 3-piece 1/2" drive deep impact socket set. Crafted from hardened chromium-molybdenum (CR-MO) steel and fitted with Teflon-coated nylon protective sleeves, these sockets are engineered to remove and tighten wheel nuts without scratching or damaging your alloy rims. Perfect for home mechanics, tyre shops, and professional automotive technicians alike.

Key Features

• Wheel-Safe Teflon Sleeve: Hard-wearing nylon sleeves coated with Teflon (not basic plastic) cushion the socket against your alloy wheel, preventing costly scratches and scuffs.
• Premium CR-MO Steel Construction: Made from hardened, tempered, and anodized chromium-molybdenum steel for exceptional strength and long-lasting durability.
• Three Essential Sizes in One Set: Includes 17mm, 19mm, and 21mm sockets — the most common wheel nut sizes for cars, SUVs, and light trucks.
• 1/2" Square Drive: Compatible with all standard 1/2" drive pneumatic air guns, impact wrenches, and breaker bars.
• Colour-Coded for Instant Identification: Gold (17mm), Red (19mm), and Blue (21mm) colour coding lets you grab the right socket at a glance.
• Deep Wall Design: Each socket is 77mm in length, providing deep reach to seat fully onto recessed wheel nuts.
• Convenient Storage Box Included: Comes with a neat storage case to keep your sockets organised and ready for action.

Frequently Asked Questions

Q: Will these deep impact sockets fit a standard pneumatic air wrench?

A: Yes! All three sockets feature a standard 1/2" square drive, making them fully compatible with pneumatic air guns, impact wrenches, torque wrenches, and breaker bars with a 1/2" drive socket.

Q: How do the Teflon sleeves protect my alloy wheels?

A: The Teflon-coated nylon sleeves wrap the outside of each socket, creating a protective barrier between the metal socket body and your alloy wheel rim. This prevents metal-on-alloy contact, keeping your wheels scratch- and scuff-free during tyre changes.

Q: What wheel nut sizes do these sockets cover?

A: The set includes the three most commonly used wheel nut hex sizes: 17mm, 19mm, and 21mm. These sizes cover the vast majority of passenger cars, SUVs, crossovers, and light trucks on the road today.

Q: Are these sockets suitable for regular hand use as well as power tools?

A: Absolutely. While the CR-MO steel construction is rated for high-torque impact use, these sockets work equally well with hand ratchets and breaker bars for controlled tightening.
