Anyone have an idea where to get some more TPS mounting screws?
The dealer wants $21 for them! Checked several hardware stores and can't find a screw with the same threads, 10-32 is close but not quite it. I'd prefer the ones with a hex slotted top so I don't strip the torx head again.

 

The TPS mounting screws are 4.5mm x .75mm pitch. These shoud be easy to find at a fastener supply house. They should have several different styles of screws available.

 

Thanks for the size info alloy. Its probably the only screw on the car thats metric thread!

 

...never had any luck locating those odd ball screws. Nobody had the right size...Grainger, Mc Master, Fastenal, Neill Lavielle, nobody. The only place that could get them was the dealership. I got tired of looking anymore so I drilled and tapped them out to the closest standard thread. I believe it was 10-32....been a while since I did it.

 

There's a few junkyards a few miles down the highway, guess I'll go make the rounds down there looking for a few spares.

 

Boy, are you in for a surprise.

Of note, the stock TPS screws are made of alumnium and strip very easily.

 

$21 is list price for a fastener kit which includes the TPS screws, washers & ID plate screws. Try here: http://www.gmpartsdirect.com
the part# is 17110848

 

Aubichon Hardware should have plenty. Mine did. Other hardware stores should be well stocked too. If all else fails, try fastenal.com.
