Review: The Best Tools Ever Made!! - These are the best 1/4" extention bars ever made. I paid over £100 for 3 well known branded ones and they are complete garbage compared to these. My friend and co-worker had put me on to these. He's had his for 12yrs and they're still like new work wise. Am Tech are in my opinion the best tools on the market and their prices can't be beat. I just keep adding more Am Tech tools to my collection and none have ever let me down. They are so well engineered and work so well I can barely believe the price is so low.

Thanks** A: HI these are a 1/4" square end, as long as your universal socket is that size then yes. or even with a reducer this would work ( if your universal socket was 1/2") **Q: Not clear about the sizes. Is the drive 1/4 inch and the bit that goes into the socket 3/8 inch?** A: 3/8 drive.. **Q: Is the drive 1/4 inch (the hole that fits on the ratchet)?** A: YES THEY ARE 1/4" SQUARE MALE ONE END & 1/4" SQUARE FEMALE THE OTHER END & THEY PUSH TOGETHER TO MAKE UP DIFFERENT LENGTH COMBINATIONS BUCKO COVENTRY **Q: Can this be used to extend a standard wrench to create leverage in order to unscrew something very tight? (a bike cassette)** A: They won’t create leverage they will just give you extra length , like if you have a nut down a tight hole , so they extend your reach. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The Best Tools Ever Made!! *by M***M on 11 August 2019* These are the best 1/4" extention bars ever made. I paid over £100 for 3 well known branded ones and they are complete garbage compared to these. My friend and co-worker had put me on to these. He's had his for 12yrs and they're still like new work wise. Am Tech are in my opinion the best tools on the market and their prices can't be beat.

I only needed this as a spark plug extractor on the car, to fit my thin wall 16mm spark plug socket by Sealey, which is 3/8ths socket fitting. So it will be used rarely and it doesn’t matter too much how it is, as long as it does the job! Note lengths are22.5cm, 14.5cm, 7cm (not 15 and 7.5cm for latter two). (Length will change when in socket etc!) - Two of them should still reach into my engine block down a 10.5cm hole. Some may care, but I do not, because it just needs to do the job! The chrome colour looks like it may simply flake off at some point. The ball and spring on the long bar is weak and doesn’t hold the socket if I apply a small amount of pressure to pull them apart - the others are perfect. The middle bar at wider flange had some sharp edges on the flange, but easily filed/scraped off - be careful when you first handle them. So all in all - great price - does the job - only need them for spark plugs. ## Frequently Bought Together - Amtech I3700 3 Piece 6mm (1/4'') Short Extension bar Set - OriGlam 1/4-Inch Drive Ratchet, Quick-Release Ratchet, Drive Quick Release Ratchet, Drive Flex Quick-Release Ratchet, Drive Torque Wrench for Repair Tools - NEILSEN TOOLS CT0753 11 Piece Drive Deep Socket Set on Holder,1/4" --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/50704085-i3700-3-piece-6mm-1-4-short-extension-bar-set](https://www.desertcart.com.ar/products/50704085-i3700-3-piece-6mm-1-4-short-extension-bar-set) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-16*
