Torque spec comes into play after a fastener has been chosen. Bolt torquing is very important. When you thread and tighten a bolt the melt stretches a little, but the metal doesn?t want to be stretched so it resists the stretches and this is where you get the holding power from. This is why when you over tighten it can?t hold the load because it can?t return to its normal shape. Further to this in time the bolt continues to stretch and will end up snapping.

Torque-to-Yield Bolts

A torque to yield fastener is a one-time use that is based on this torque principal we just talked about. The torque spec usually have a 25% safety feature giving you a 25 per cent over tightening leniency. The torque to yield bolts don?t have this safety buffer. They are not meant to stretch the metal. This may sound like a disadvantage but it?s not really. They are extremely strong as they afford the whole 100% of their strength whereas the basic bolt only gives you about 75%.The one disadvantage they do have though is they can only be used once. So if you remove them you have to replace them with a TTY (torque to yield) bold. You are going to end up with 25% less strength with the basic fastener.

The TTY are used in many cases so it?s important for the technician to be aware of this during the estimation process of the procedure.

Tightening Sequence A tightening sequence can also be specified in conjunction with torque specs. A crises cross pattern is use to install wheels and now some installation patterns are being suggested for body panel fasteners. There is a certain amount of expanding and contracting during temperature fluctuations with composite panels. This means the fasteners have to adjust to these changes and must be designed to allow for this.

Shop Tips Whenever possible replace the fastener with the same type as the one your remove. Check the manual however to ensure it is the correct part and you are doing the proper procedure. Every part is specific because there is a reason for it.

Keeping track of what you are removing is important and time saving so tossing them in a pile is not the answer. Just use some small plastic bags, put them in and then mark what they are on the outside of the bag.

If you do not have a manual, you can ask a dealership to show you their service manual.

Use all the parts that come with your replacement parts.

If you are not sure about the label, compare height, thread pitch and diameter to the new piece and this will help you choose the right replacement fastener.

Make sure to use coated materials to prevent corrosion. A classic example of making this mistake is using a non-coated steel boat with an aluminum panel. If the coated items you require are not available then use a plastic or fiber gasket, a washer or even a layer of paint to produce a barrier between the materials.

Vandalism of property is a costly endeavor not only for the recipient in damage repairs but also for the one being so destructive when they land in jail. Throwing eggs at cars may seem like a harmless prank. In fact, though it is not harmless as it leaves stains on some car paint finishes. If there is a great deal of staining it could mean having to the have, the car repainted. Now that harmless prank has turned into hundreds of dollars worth of damage.

There are some individuals that have said that Vaseline Intensive Care Lotion rubbed into the egg stain and left for five minutes then removed works well. I haven?t seen this in action so it?s hard to say how valid it is.

There are two solutions you may want to try before taking it to the auto repair shop.

Method One

Step One Most often what happens is if the egg happens to hit the car the wrong way if will chip the paint. So first, you need to assess the damage very carefully. If the paint is not chipped you can try this method, otherwise you need to go to method 2.

Step Two Purchase some very high grit sandpaper and soak a strip of it in water overnight. The paper must be saturated with water.

Step Three Sand very lightly the stained area with the sandpaper you had soaking in water overnight. Do not apply too much pressure and make sure you keep the sandpaper wet.

Step Four Rinse the area well and dry it. You now need to use a rotary polisher. This should remove any marks that the sanding may have made. The technique you have utilized here is a smooth service that has had a clear coat melted into it.

Step Five Now you are going to want to eliminate the swirl marks and you do this by applying a pure polish and buffing it in.

If the egg stain mark is not gone then you will have to resort to step two.

Method Two Fold an extra strength paper towel into a square and place it over the egg stain. Then spray the paper towel with brake cleaner being sure to keep it confined to the area of the stain. The brake fluid may removed some of the car paint so be absolutely sure not to get it anywhere except on the stain itself.

If the car is badly chipped you will need to sand it down, and then touch it up with some car paint.

Removing permanent stains from cars can be very difficult. In order not to end up having to do a full paint job you would be much further ahead to take it into a paint repair shop and have it professionally done. All too often do it yourselfers have ended up costing themselves a great deal of money thinking they could repair a problem themselves.

Ideally if there is vandalism in your area you would be wise to keep your vehicle in a shelter location if possible.

Let it dry for about 1 hour then you could apply the clear coat. Let dry fifteen minutes then re apply. You'll in all likelihood need about 3 coats of the clear to get a nice finish.
