About this item

  • Knurled band provides grip for starting or turning loosened fasteners with fingertips
  • Polished, chrome-plated finish easily wipes clean and is highly resistant to corrosion
  • Beveled drive end helps guide extension smoothly onto drive tool
  • Four detent grooves offer a secure connection with the drive tool
  • Radiused corners inside the drive avoid stress concentrations that can cause cracking
  • Spring-loaded retaining ball latches into sockets and holds them securely in place


Adding extra length to get past obstructions or into tight, narrow spaces, Tekton Extensions access hard-to-reach fasteners, allowing you to work faster and avoid extra disassembly steps.

Tekton makes great quality hand tools. I really like these 3/8" extensions. You can tell they are well made as soon as you pick one up. I will be using these extensions primarily for automotive repairs. But they would work well for anything, really. Home repairs, contractor/construction jobs, etc.Excellent value for the money. Better quality than the tool schmuck...err, tool truck brands. Extensions fit well into sockets and wrench. I have no worries about them coming loose while using them.I would recommend these Tekton 3/8" extensions to others.

I have wanted a couple 1 inch extensions for when changing spark plugs on my wife's Subaru. Finding these from Tekton, I ordered them. They appear to be of the quality I would expect from Tekton. The nickel plating is nice, stamping is clear, and the sizing is correct.

Purchased this as I could not find anything more than an 18" extension in any of the local or box stores.Just did some O2 sensor changes on a Jeep and, although not overly difficult without this tool, had I had this extension I wouldn't have had to contort my hands like I did without it.This extension will allow you to get into areas that may have previously required you to remove body and engine parts.Made sturdy and I don't see having any major issues. I bought the 3/8" drive so there has to be torque limits but I believe this extension should hold up well.

Gets the job done. Doesn’t feel cheap, hasn’t broke yet, & gets the job done! Not a bad buy, especially considering the price 10/10

Tekton 3/8 drive long extension set is decent for what they are. I use mine in a medium duty industrial setting and they work great. I don't believe they'll hold up to impact guns and heavy duty use. But that's just my opinion.I like tekton, but they're not the toughest around, but pretty darn good for the price point.

The little bitty 1 inch extension shipped out quick and arrived on time.Shipped in a plastic bag.The socket seems well made and looks great like all Tekton tools.It's a wee bit short for a 1 inch extension but works great for what I needed.I have many different Tekton tools and yet to break or have a problem with one.I would buy again and recommend.

Good quality item with nice knurling. The only issue I had with it was the shaft diameter was wider than I realized so it did not fit the case for the one I was replacing.
