## Overview

The Sunex 3351 is a 51-piece 3/8” drive impact socket set crafted from durable Chrome Molybdenum steel. Featuring metric sizes from 7mm to 22mm, it includes standard, deep, and universal sockets, plus a universal joint and 3” extension for hard-to-reach fasteners. Its radius corner design enhances torque and reduces wear, while dual laser and roll-stamped markings ensure permanent size identification. Packaged in a heavy-duty storage case and meeting ANSI standards, this set delivers professional-grade performance backed by a lifetime warranty.

## Description

The Sunex 3351 3/8” Drive Impact Socket Set includes metric sizes from 7mm to 22mm in standard, deep, and universal lengths. This set includes a universal joint, a 3” impact extension, and a ¼” bit holder socket. Each socket has been forged from high grade Cr-Mo steel, designed with radius corners, made with chamfered openings, and marked by both laser etching and roll stamping to ensure permanent socket identification. All of this ensures our sockets’ professional-level performance--conveniently stored in one heavy duty storage case. Meets ANSI Standards.

Review: This set has been amazing for working on my car. Fits extremely well to all heads, very well organized, and great value for an entire set of metric 3/8" sockets. Having both a universal 3/8" swivel head as well as a set of sized socket swivel heads has been super clutch on some buried screws. I'll probably never need to use their warranty since I'm not using them everyday, but for an enthusiast they have held up well (no fading of numbers yet).
Review: Very good build quality and finish. Durable and strong feel with positive ball lock on to driver or wrench. Used under high torque loads already.
