Do you need to replace Grade 2 bolts?
Rated hardware will have a lower yield strength than their breaking tensile strength, however, once the metal has been stretched, it is recommended it be replaced, as this stretching reduces its tensile strength under subsequent stresses. Bolts with no head markings at all are referred to as Grade 2.
When do you need to know the size of screws and bolts?
If you have some stray screws and bolts (a.k.a. fasteners) lying around and aren’t quite sure what size they are, or if you need to replace a missing bolt on a piece of machinery and need to know what size to get, here are some methods to easily figure that out.
What kind of nut should I use to replace a lock washer?
When replacing nuts, washers or lock washers, it is essential that you use hardware of the same grade or higher to ensure the bolts can still meet the specified strengths for each grade. A Grade 8 bolt can be compromised when held in place with a grade 5 or nylon-insert style nut.
Can you check the size of nuts and bolts?
So something like this only works with bolts and nuts that you can bring with you to the store, but not all hope is lost! If you plan on using them a lot, it might be worth it to invest in some sizing plates and thread checkers for yourself, some of which you can use on that engine as discussed above.

Can a quarter panel be mounted on a wheelhouse?
A metal panel that serves both as a rear inner fender piece and a structural support member bolted to the vehicle body. A quarter panel wheelhouse can also serve as a mounting point for a rear quarter panel. See our page for OER Wheel Houses .
