Universal Impact Socket
The Capri Tools 3/8 in. Drive Universal Impact Socket rotates 360 degrees for access to fasteners at difficult angles. It is built from premium Chrome Molybdenum steel with a proprietary heat treatment to withstand high torque from power tools. A manganese phosphate coating provides superior corrosion resistance compared to standard black oxide finishes. The 6-point WaveDrive design grips flats tightly to prevent rounding and increase leverage.
Technicians needing angled access
Mechanics who regularly work in tight engine bays or around obstructions will benefit from the universal joint movement. The socket meets ASME B107.110 standards for professional use. Buyers who only need straight-line access on open fasteners will find a standard impact socket simpler and more rigid. Anyone requiring a different drive size or socket diameter must select another model.
High-torque fastening headroom
The Chrome Molybdenum construction and heat treatment handle repeated high-torque impacts from pneumatic or cordless tools without cracking. The WaveDrive geometry distributes force across fastener flats rather than corners, preserving both the socket and the bolt head. The manganese phosphate finish resists rust in wet or salty environments. The joint mechanism remains the limiting factor; extreme torque at sharp angles can exceed its strength.

Questions about this item
What drive-size ratchet or impact gun is needed to run the 3/8 in Drive Universal Impact Socket?
A 3/8-inch drive ratchet or impact gun is required; the socket's square drive matches that size exactly.
Will the 360-degree swivel on the 5-3351 clear obstacles that a fixed socket cannot reach?
Yes, the universal joint rotates a full 360 degrees, letting you angle the socket around obstructions while keeping the drive engaged.
How can I verify the 6-point WaveDrive profile is gripping the fastener correctly after I seat the socket?
The WaveDrive flats should sit flush on all six fastener corners with no visible rounding; the manganese-phosphate coating will show even contact marks when torque is applied.
