stuck bolt! argh!

[dеiтайожни]

The top front bolt of my assist steps mount won't budge! Any suggestions? I've used an 18" ratchet extension, normal ratchet, adjustable wrench and so on and it's not budging, been trying for like an hour and all it's doing is stripping it. and I'm the one that tightend it last!

Heat it up

Impact wrench.

Cut it off and replace bolt.

[Desert Dan]

WD-40 and wait a few minutes.

Are you sure you are turning the correct way?

Don't laugh we have all that before

I've had better luck with liquid wrench,

[deserth3]

Heat the bolt. Carefully

[HummBebe]

Use a box end instead of the socket, you can hammer on it a little.

[wpage]

Liquid Wrench then hot & cold.

Bigger wrench or put a pipe on a ratchet to make it longer, thus more leverage.

thanks, took like 3 hours but I finally got both of them! Had to use all the suggestions.

Now, anybody have the p/n for those bolts?

Just match them up at the hardware store.
Buy the strongest ones they have in stainless,and replace them all
Put a little anti sieze on threads.(used for lug nuts,spark plugs ect)

I agree, anti-seize is good for these bolts, but beware, NEVER use them on lug nuts. Lug nuts are designed to torque to a specific spec DRY. Adding any type of anti-seize to a bolt/stud will cause incorrect torque.

What is the torque spec for the lugs??

103 lb ft (140 N?m)

And I'll even through in the GM fastener notice:
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

I'd stay away from Stainless Steel bolts. They are known for galling. Stainless bolts are good if you plan on not removing them and don't want any rust. But for an aplication that needs to be removed numerous times Stainless doesn't work so well.

Here's a little more information about it.

Galling only occurs when both parts are stainless steel and completely dry. If the other part is steel and the bolt is stainless, galling is not an issue.

Also, if galling is a concern, a little bit of anti-sieze (note: little bit) will prevent galling if both parts are stainless.

I work with stainless steel bolts as a profession.

Besides, stainless steel (Depending on the grade, but most common is 18-8 unless you go to specialty stores) is not the strongest. If you want strong, I'd go with carbon steel bolts.
