21mm 3/4' Drive 4pt Budd Wheel Impact Socket

Features

• 21 mm socket size — fits standard 21 mm hex fasteners.
• ¾″ 19.05 mm) drive — matches large format impact wrenches used in automotive and industrial settings.
• 4-point Budd-wheel design — provides robust engagement and reduces rounding of fasteners under high torque.
• Impact-rated tool steel construction — built to withstand the stresses of impact-wrench applications.

Benefits

• Durable for high-torque use: The impact-rated build means you can rely on this socket for heavy jobs without premature damage.
• Reduced fastener damage: The 4-point contact design distributes load more evenly than some standard sockets, helping protect bolts and nuts.
• Workshop-ready format: ¾″ drive size and 21 mm socket size are common in heavy equipment, automotive service and industrial maintenance.

Extra Information

• Ensure compatibility of your impact wrench and socket drive size — this socket requires a ¾″ drive machine or adapter.
• Use appropriate safety gear when operating impact tools (eye protection, hearing protection, gloves) due to high torque and vibration.

Specifications

Safety

• Wear eye, ear and hand protection when using impact tools—chips or fastener fragments can be ejected.
• Ensure socket is seated fully on the fastener before applying impact torque to avoid slipping or damage.
• Use correct size socket for the fastener—mismatched size can lead to rounding or socket breakage.
