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.
Review: Just the job! - A tad cheap and cheerful but just what I needed to reach the spark plugs in the bowels of my car engine. Very reasonably priced and quick delivery.

## Questions & Answers

**Q: Would this work with a universal socket? 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.

### ⭐⭐⭐⭐ Decent quality, decent price
*by Y***S on 21 July 2023*

Really handy set of extension bars. Quality is fine, but not top-notch. Great for someone like me who uses them occasionally, but if you're going to use them every day you may want to look elsewhere.
