## Overview

The TEKTON 1/2 Inch Drive x 21 mm Deep 6-Point Socket is engineered for exact hex fastener fit, preventing round-off with its 6-point geometry. Its deep socket design reaches recessed bolts and long shafts, while the polished chrome-vanadium steel finish ensures corrosion resistance and easy cleaning. Large, permanent size markings enhance usability, making it a reliable, long-lasting tool for professional and DIY use.

## Description

Tekton deep 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.

Review: Super high quality! - Perfect! A high-quality item from Tecton. I've bought many items from Tecton and they all have been head and shoulders above Craftsman. You can't go wrong with this brand.
Review: Works great for Model 3 - Bought this to use on a Model 3. Works great for tightening the lug nuts. This is the only reason I bought this size. Quality seems just as good as name brands out there.
