Why No Appliance Fastener Torque Specs?

[lothian.mcadam]

I'm reassembling my washer after a minor major repair. It's surprising how few fasteners are used in these things.

What's more surprising though is there are ZERO fastener torque specs printed in the service manual. A quick perusal of various brand's service manuals reveals the same. Why is this? What, 'frinstance, is the torque spec for the damper fasteners into the frame and the tub. And the tub fasteners. And the counterweight fasteners. And the motor bolt. And the head bolts, the CV axel bolt, and lastly, the washer's onerous crank pulley bolt?

Merely spinning fasteners to "that feels tight" snuglyness seems like the sort of hack approach typical of a professional appliance tech. I want to a value to dial in to a torque wrench, just like the Mexican factory  worker used when assembling my washer at the first.

Lol, yeah good luck.

You must be a brilliant engineer or something.

Oh to answer your question. Because they simply are not needed.

Several products i service use 

FT , fucking tight 

Its fantastic on those chinesium screws they use 

there would be a spec in manufacture but lets face it its not really life and death in majority of cases like in say a motor vehicle

They're terrible screws being driven into thin steel and aluminum and plastic and either the screw or the material will strip with very little torque.

The other reason is who would spend money on a inch pound or inch once torgue wrench.

FWIW, my screw gun has a torque limiter although it's not calibrated to any particular standard. 

#1 setting is low enough that I can hold it back with my fingers and #20 will strip most of the screws, I usually use #5. I's some particular value but I have no idea what.

Once upon a time i had a little bosch like that which was 7.2v 

i bought it cheap and it was awesome 

Small lmlight weight and did everything i needed it to cheap , perfect fit in the toolbox 

The torque settings were perfect for plastic panel screws 

sadly ive never been able to find another 

The 12v drill i have now is pretty good and i have found good success with using the torque settings for undoing the chinesium screws , you can get a good pressure into them and by starting low on the torque setting it works a little like a rattle gun and gives some shocks to the screws breaking them free from the paint 

the vessel impacta screwdriver is an absolute lifesaver on these screws too

Amazon has the Bosch. Best tool I own. I'd probably have to stop doing service calls if I had to turn everything by hand.
