## Overview

The TEKTON 3/8 Inch Drive x 21 mm Deep 6-Point Socket (SHD13121) is a durable, chrome-vanadium steel tool designed for professional-grade hex fastener work. Featuring a corrosion-resistant chrome finish, large permanent size markings, and a 6-point socket opening that prevents fastener round-off, it ensures precise, secure engagement with drive tools. Ideal for automotive and industrial use, this socket combines longevity, accuracy, and value in one sleek package.

## Description

Tekton deep sockets have large, stamped markings that are permanently impressed into the material by a roll-stamp die and are as large as possible while still being readable along the socket's curved surface. The exterior of the socket is chrome-plated to resist corrosion and wipe clean to a mirror finish. The interior is protected against corrosion with chrome plating that is supplemented with a clear coat or painted finish where needed for full coverage. The 6-point socket opening provides an exact fit and maximum contact for hex fasteners. Radiused corners prevent fastener round-off by applying force to a fastener's flat sides, rather than its corners. Four detent grooves provide a secure connection with the retaining ball of a drive tool, and beveled inner rims help guide the socket onto other tools.

Review: Good quality at a good price. - Good quality (nice chrome plating, legible lettering). Actually seems closer to spec than the major brand socket set that I am adding this to. I have now used it several times and it fits the bolts well. I used it to remove a slightly rounded bolt that would not come out with other sockets/tools. All in all, good quality at a good price. I recommend it.
Review: Sturdy, precise, and great value - I recently picked up the TEKTON 3/8″ drive, 10 mm deep socket (model SHD13110), and it’s quickly become a favorite in my toolkit. 👍 What I Love: Accurate fit & strong grip: The 6-point design grips fastener flats (not corners), which helps prevent rounding—even on stubborn bolts . Useful deep length: The deep-well design (about 0.75″ recessed depth) reaches nuts on longer bolts—ideal for automotive and bike maintenance . Clear, permanent markings: Size is die-stamped and easy to read; it won’t wear off even after regular use . Quality construction: Chrome-plated finish resists corrosion and wipes clean, plus the interior clear-coating prevents rust . Solid value: Smooth machining, sturdy feel, and at around $5, it’s a great price-point compared to competitors . 🔧 Real-World Performance: It fits snugly on hex bolts and slides onto drive tools seamlessly thanks to four detent grooves and a beveled inner rim . I used it for tightening bike stem bolts and car maintenance—it performed flawlessly, no slipping or rounding. ⚠️ Minor Consideration: This is a handheld socket—not designed for impact tools. Don’t over-torque it, and it’ll last you a long time. --- Final Verdict: A compact, well-built socket that nails the essentials—accuracy, durability, and value. If you’re building or topping off a metric socket set, this TEKTON 10 mm deep socket is a smart pick. Highly recommended!
