## Overview

The TEKTON 3/8 Inch Drive x 21 mm Deep 6-Point Socket is engineered for professionals who demand precision and durability. Its 6-point geometry grips hex fasteners securely to prevent rounding, while the deep socket design reaches recessed bolts with ease. Finished in polished, corrosion-resistant chrome, it features large, permanent size markings and a secure connection system, making it an essential tool for any serious toolkit.

## Description

Tekton 6-point sockets are ideal for working with hex-shaped fasteners. They're designed to grip the sides and not the corners of the fastener heads, which prevents round-off. Their extended length allows the deep socket to fit over long fasteners and reach into recessed areas. The large, die-stamped markings are permanently impressed into the material and optimized for readability.

## Features

- 6-point socket opening provides an ideal, exact fit for hex-shaped fastener heads
- Socket geometry is designed to apply force to flat sides of fasteners and not the corners, preventing round-off
- Deep-length sockets reach into wells and accommodate the excess threads of longer shafts
- Extra-large die-stamped size markings are easy to read and can’t wear off
- Polished, chrome-plated finish easily wipes clean and is highly resistant to corrosion
- Four detent grooves provide a secure connection with the drive tool
- Beveled inner rim of the socket opening helps guide it smoothly onto fasteners

I bought this to replace the one I lost from my set. It is a perfect fit for the case. Great socket especially for the price. I use it almost daily and it has outlasted my dads Gearwrench set.
