UMPH Tool Review: Rounded Nut & Bolt Extractors



No prizes for guessing that rounded nuts and bolts really, really piss me off!  Especially when their recalcitrant refusal to budge stands between me and and job-done-let's-have-a-beer-time!!


The example shown two photos above secured the Galant's tow-point and its recently re-sprayed stone-tray to the front chassis rail and had decided to go rounder than a rissole just as the final twist of the socket was applied.  (Insert profanity of your choice here - it's unlikely to be saltier than my rich and spectacular vocabulary was able to furnish at the time!). 


Normal recovery protocol involves vice grips and more un-PC language.  However, the hex was positioned such that getting anything other than a socket or a ring-spanner anywhere near it was impossible, requiring a reciprocal increase in verbiage your mother may not approve of. 

 A visit to the interweb flagged up two apparently achievable options that didn't involve welding a makeshift lever onto the remainder of the hex.  One was the highly recommended Irwin nut and bolt extractor, which received rave reviews but didn't seem to be available locally, and the other a variation on the much the same theme by ProTool.


ProTool's version would appear to be of the same design as all the other not-Irwin ones out there from the likes of Repco, Kinchrome and several other credible tool manufacturers.  As you can see from the photos above, this style has teeth that bite into the rounded periphery of the nut or bolt head and gives sufficient purchase to undo it.  

 The image of the bolt above shows just how badly rounded it was and demonstrates how effectively the tool removed it (two minutes' effort -v- and hour and a half of frustration and failure).  Job done!

 The nut and bolt extractors I bought were 1/2 inch drive.  However, 3/8 drive versions are also available at reasonable prices.  I wouldn't necessarily only recommend ProTool; any of the others in the same style are likely to work just as well.

 Verdict:  10/10 for performance and value.  The ProTools are made from chrome molybdenum, so I can't see them wearing out in a hurry, either.

    I like and suggest you to try LongPathTool program. It is very helpful for copying/deleting or renaming long path files.

EJ or EH Holden? (Up-dated December, 2022)

EJ or the later EH? Several years ago, I posed the question:  Can somebody please explain the difference between an EJ and an EH Holden ute or van?  The response at the time wasn't overwhelming, so I did a bit of Googling and ferreting through my photos and came up with my own rough guide to EJ and EH identification.  Sedans and wagons are easy to tell apart ;  the EH's vertical rectangular tail lights are a dead give-away.  However, the workhorse versions of both models share the rear-end treatment of the earlier EJ, making it harder to identify one from the other.    No super obvious hints here. Or here ...  . It turns out that the main clues are in the placement of the front   H O L D E N   lettering and GMH lion emblems, the style of the radiator grille and the width of the vents in front of the windscreen, with all EJs - sedans, wagons, utes and vans - having one combination and the EH line-up having their own . So what exactly are those diffe

Vick Auto Prima Fiat X1/9 Brakes: An Owner’s Assessment

At the end of 2022, I fitted a set of Vick Autosport Prima front brakes to my mildly worked 1.5 litre Series 1 Fiat X1/9 . I was fortunate, having picked them up at a very, very reasonable price, brand new but surplus to the needs of a fellow X1/9 Australia member who had imported them from the US. The kit included: New single pot callipers , new vented rotors (standard X1/9 front rotors are smaller, non-vented items), DOT approved stainless steel brake hoses, and all the necessary mounting hardware. They are a value proposition, being particularly well priced compared to other manufacturers’ packages - even at RRP - with everyone I’ve spoken to saying they’re made to a high standard, too. Here's a link to a piece that I wrote about them at that time, including some costings: https://uppermiddlepetrolhead.blogspot.com/2022/11/the-x19-gets-prima-brake-upgrade.html . Initial Assessment: I was a little underwhelmed by the brakes' performance, finding that although they had a tiny

Random # 301: Nanna-Spec KE36 Corolla

  Once upon a time - six or seven years ago, actually - there was a lovely pale yellow GC Galant station wagon getting around Hobart.  It was totally nanna-spec; its paint was umarked, the chrome work and hubcaps were immaculate, and its very original interior was pristine. Then someone stuck feathers in its dashboard.  Next, the windows were adorned with Tibetan prayer flags.  And a hubcap went missing.  And the the rear bumper was pushed in, mangling the bodywork behind it.  And a mudguard got dented.  And rust set in.   I fear for this sweet, innocent KE36 Corolla.  Somebody please save it before it's too late.  Nanna needs you to do it.
