Description of Performance Tool W32139 Extension 3 Piece
Extended length long for hard to reach nuts and bolts. Heavy duty alloy steel for strength and durability. Chrome plated finish with knurled grip. Sizes: 18", 24" and 30".
I got these primarily for tightening our basement wall braces and they work well for that. Little torque (45 ft-lbs) but I didn't notice much flexibility in them for this purpose. They seem pretty straight for what they are and are a decent weight so I'm not really worried about them.
For my current project I needed a 24" extension but after comparing the prices of other two piece single extensions I decided I "need" this one because I never know when I might need a 36". 24" used in my project, checked two other nuts for loosening and re-tightening - these things are solid. I would buy again anytime (if I lose them or they get stolen). I doubt I'll ever bend or break them.

High tensile alloy steel for strength and durability
I bought this extension set at a hardware store. I was preparing for a timing belt job and chose this kit to help me get to the engine bay to remove the engine side mounting bolts and harmonic balancer. Some flex in overtime is inevitable, but that was just ridiculous. The engine mounting bolts are torqued to approximately 40 ft-lbs. This machine is from 2007, so the screws were still tightened at the factory. The 18" extension had so many kinks that when the nut snapped, a massive shock wave…
