## Overview

The TEKTON 1/2 Inch Drive x 21 mm Deep 6-Point Impact Socket (SID23121) combines dual laser and stamped size markings with a deep interior well for enhanced fastener engagement. Crafted from high-grade 50BV30 Chromium-Vanadium steel and finished with a corrosion-resistant manganese phosphate coating, it prevents fastener round-off with radiused corners and fits both friction ring and detent pin anvils, making it a versatile, durable choice for professional-grade toolkits.

## Description

Tekton deep impact sockets have two size markings—both a high-visibility laser marking and a permanent stamped marking. The interior well of the socket extends fully into the socket, which allows for better fastener engagement in more situations. Each socket works with both friction ring and detent pin anvils. Smooth walls without grooves support friction ring engagement, and a detent pin hole on one side allows you to decide whether to engage the pin. Radiused corners on the socket prevent fastener round-off by applying force to a fastener's flat sides, rather than its corners. Part by part, we choose the best combination of steel alloys, heat treating specifications, and forming processes to meet the highest performance requirements. This socket has a corrosion-resistant manganese phosphate coating.

Review: Top Quality Tools From Tekton.. - I purchased this because another brand socket set I purchased didn't come with a 16mm. So now my set is complete. I have use this socket and its heavy duty and fits perfectly. Tekton is high quality. I have alot of Tekton tools and none have failed.
Review: Great product - Fits right, easy to use. Good thickness. More importantly it helps me fix my things with out any hassle.

## Features

- Works with Friction Ring or Detent Pin Anvils – Smooth walls inside the drive end and a detent pin hole make the sockets compatible with both drive tool anvil types
- Prevents Fastener Round-Off – Radiused corners prevent fastener round-off by applying force to a fastener's flat sides, rather than its corners
