Flared Screwdriver Torque (geeks only)

Recommended Posts

Best small engine screwdriver needs replacing. (there's an exciting topic). Weraltt Kraftform  Vanadin Germany .

Massive amount of torque because of the flare (which doesn't taper back in). Can't find anything like this online. It was originally covered in red insulation which I cut off - so maybe electrical screwdriver? Any doctors of screwdriverology out there? Alternative?

Shaft 125mm, Tip Thickness about1.2mm. Width at flare 5.5mm.

Any good?

 

Cheers Ratman - not sure but closest so far - cheers - the tip is not the same & the shaft seems thicker. (ordered one to try). What is great about mine is that it stores energy like a spring (you can feel shaft twist slightly) then unleashes it. The full width head (once it opens out it doesn't come back in) also seems to deliver more torgue . I read a paper on this years ago & that bit of extra width works wonders :) Had a minor meltdown a couple of yrs ago when I mislaid it :)

I know that feeling! Or when someone “borrows” some thing! [emoji849]
They have the lazer cut tips on em now which is meant to help grip/torque. I have the impact headed ones too that have the 1/4” drive built in so you can use a ratchet with them, helped me out loads on jobs which my hands just cant get enough grip on!
