Capri Tools 5-3318 3/8 in Drive 18 mm Universal Impact Hand Socket

SKU CH-KASX-DFG0N

An 18 mm universal impact socket with 360-degree rotation for hard-to-reach fasteners

  • ColorTransparent
  • 360-degree rotation reaches tight fasteners easily
  • Chrome Molybdenum steel withstands high impact torque
  • Manganese phosphate coating resists corrosion better than black oxide
  • 6-point WaveDrive design prevents fastener rounding
  • Meets ASME B107.110 professional quality standards

3/8 in Drive Universal Impact Socket

This 3/8 in drive universal impact socket fits 18 mm fasteners and is built for high-torque power-tool use. It is intended for mechanics and technicians who need reliable access to stubborn or awkwardly positioned bolts. The universal joint allows the socket to pivot freely. The manganese phosphate coating resists corrosion in demanding environments.

Practical limits of the universal joint

The socket rotates 360 degrees to reach fasteners at difficult angles. This range of motion is the defining limit of the universal design; beyond it the joint cannot transmit torque effectively. The 6-point WaveDrive profile grips the flats of the fastener to reduce rounding under load. Impact-rated construction handles the shock of repeated hammer blows from powered drivers.

ASME B 107.110 compliance

The socket meets and exceeds ASME B 107.110 standards for dimensional accuracy and strength. This certification is the single specification that confirms the tool is suitable for professional impact applications. Buyers who need a socket without universal articulation should choose a standard impact socket instead. Buyers who require a different drive size or fastener size must select another model.

Questions about this item

Should I choose the 18 mm socket or a different size for my 3/8 in drive set?

Select the 18 mm socket when you need to turn 18 mm fasteners; match the socket size to the fastener size for proper fit.

What does the 360 degree rotation do when the socket is on an impact gun?

The universal joint swivels 360 degrees, letting the socket reach fasteners at angles a straight socket cannot.

Does the ASME B 107.110 standard limit the torque I can apply with this impact socket?

The standard sets performance and dimensional requirements; the socket is built from chrome molybdenum steel with manganese phosphate coating to handle high impact torque.
