ASTM A449
ASTM A449 covers headed bolts, rods, and anchor bolts in diameters ranging from 1/4″ through 3″ inclusive. It is a medium strength bolt manufactured from a medium carbon or alloy steel that develops its mechanical values through a heat treating process. It is intended for general engineering applications.
ASTM A449 is virtually identical in chemistry and strength to ASTM A325 and SAE J429 grade 5. However, A449 is more flexible in the sense that it covers a larger diameter range and is not restricted by a specific configuration.

Hi, I’m Quinn Gifford and today I’m going to show you how to install the WeatherTech No Drill Mud Flap on this 2010 Chevy Tahoe. The unique feature of WeatherTech No Drill Mud Flaps, is that they fasten securely to your vehicle, without drilling any holes through metal or its protective rust-proof coating. We do this by using pre-existing holes and fasteners that have factory rust-proofing and paint applied. If no holes are available, we use the WeatherTech patented QuickTurn Fastener.
The QuickTurn is made of hardened stainless steel with a specially designed screw that allows a locking arm to rotate inside the fender liner. Then clamped down tightly on the fender lip, holding the flap securely in place. Not all vehicles need a QuickTurn, but
we never drill through metal, because we do not want expose your vehicle to corrosion. In the case to the 2010 Tahoe, existing
fasteners on your vehicle, and 2 1 inch stainless steel bolt will hold your mud flaps securely in place. The tools you’ll need for the Tahoe are: a small socket set, a small Phillips screwdriver, a small flat blade screwdriver and a 7/ 16th box end wrench. So let’s get started. Choose the driver side mud flap indicated by an “LH” stamped on the back. Hold it in position, and you can easily identify the existing fasteners to be removed. In the case to the Tahoe, these two hex head screws and these two plastic rivets need to be removed. Using a 7 millimetre socket, back out the screws.
Keep them handy for reuse installing the mud flaps. With the flat blade screwdriver, carefully remove the center portion of the plastic rivets. Once the center portion is removed, the outer body in the river it can be removed. Keep one on the rivet assemblies handy for installing your mud flap Now fit the WeatherTech Mud Flap tightly into position. Line up the holes in the mud flap with the existing holes and replace the hex head screw you just removed and snug them to hold the flap in position, but do not fully tighten.
Next using one other previously removed plastic rivets, insert the outer body of the rivet through the upper are the two remaining holes in the mud flaps. Insert the inner core the rivet and firmly press it in, until it seats into position. In the last remaining hole, insert the 1 inch stainless steel bolt through the mud flap, the plastic liner and the metal behind it. With the matching nut, reach behind the mud flap, and feel the bolt end and thread the nut onto the ball in hand tighten. Finally, it is important to press the mud flap firmly into position, fitting the contour of the fender. And tighten the two hex head screws and the stainless steel nut and bolt.
And that’s it! Repeat the process on the other side and your WeatherTech Mud Flaps are installed.
I’m Quinn Gifford for WeatherTech.
