3/8 in Drive Universal Impact Socket

The Capri Tools 5-3356 is a 3/8 in drive universal impact socket sized at 11/16 in for fastener work. It rotates 360 degrees to reach angled or obstructed bolts in automotive and industrial settings. The socket is built from Chrome Molybdenum steel with a proprietary heat treatment for high-torque durability. It meets ASME B 107.110 standards for professional use.

Manganese phosphate coating

The manganese phosphate coating provides superior corrosion resistance compared to standard black oxide finishes. This military and aerospace preferred coating protects the socket during heavy use with power tools. The 6-point WaveDrive design grips fastener flats tightly to prevent rounding and increases leverage. These features combine to extend service life under repeated impact loads.

11/16 in size constraint

This socket fits only 11/16 in fasteners and requires a 3/8 in drive ratchet or impact gun. It will not work with 1/2 in drive tools or metric fasteners of different sizes. Buyers needing other SAE or metric dimensions must select different sockets. California Proposition 65 warnings apply for chemical exposure risks.

Questions about this item

Will the manganese phosphate coating on the 11/16 in universal impact socket need reapplication after heavy use?

The manganese phosphate coating is a permanent factory finish that does not require reapplication; it provides superior corrosion resistance compared to black oxide.

What is the first limit reached when the 3/8 in drive universal socket is used continuously at high torque?

The 6-point WaveDrive design grips fasteners tightly to prevent rounding, so the practical limit is the fastener or drive tool capacity rather than the socket itself.

How much heat or noise does the universal joint generate during all-day impact wrench work?

The socket rotates 360 degrees for access, and the Chrome Molybdenum steel with proprietary heat treatment handles sustained high torque without excess heat or noise from the joint.
