ASTM A320
Scope Originally approved in 1948, the ASTM A320 specification covers alloy steel and stainless steel bolting materials for low temperature service. This standard covers rolled, forged, or strain hardened bars, bolts, screws, studs, and stud bolts used for pressure vessels, valves, flanges, and fittings. Like the ASTM A193 specification, unless otherwise specified, the 8UN thread series is specified on fastener larger than 1” in diameter. Below is a basic summary of a few of the common grades within the ASTM A320 specification. A number of other less common grades of ASTM A320 exist, but not covered in the description below.| L7 Alloy steel | AISI 4140/4142 Quenched and tempered |
| L43 Alloy steel | AISI 4340 Quenched and tempered |
| B8 Class 1 Stainless steel | AISI 304, carbide solution treated |
| B8M Class 1 Stainless steel | AISI 316, carbide solution treated |
| B8 Class 2 Stainless steel | AISI 304, carbide solution treated, strain hardened |
| B8M Class 2 Stainless steel | AISI 316, carbide solution treated, strain hardened |

Today on this 2002 Honda Civic, we are going to be installing part number 24706 from Draw-Tite. And this also applies to Hidden Hitch part number 60867. OK, the first thing that I am going to do is go ahead and show you the mounting locations for our hitch. It is going to be the existing hole right here and it is going to be the same on both sides. We are also going to mount here to the tow loop. Now, in order to put our hitch up, we are actually going to have to fish wire our carriage bolt and block through this existing hole here. But, it is not wide enough so we are actually going to have to make it a little wider so our parts can fit through. We are just going to use a hammer and a chisel. We are just going to check and see if our block fits through. And it seems like it does so that is a good sign. 0:41
Now, in order to take our carriage bolt and block and put it into position, we are actually going to have to use what we call a bolt leader. And we actually sell those. And it is part number 80101-1. Now all we are going to do is we are going to go ahead and stick it through the hole that we are putting our bolt and carriage block into. We are going to pull it through like that. Then we are going to go ahead and put our block on there and then thread our carriage bolt on there. It is just going to come out, pull it out of the hole just like that. We are also going to do that for the remaining hole on the passenger side. 1:18
Alright, now that we have our carriage bolts and blocks into position, we are going to go ahead and put our hitch up and tighten down our hitch using a conical tooth washer and nut for the passenger and driver sides. And then for the center attachment, we are going to go ahead and use this U-bolt. And then we are going to tighten it down with the lock washers and nuts that were provided in the kit. When tightening these down, you want to make sure you kind of keep the threads even on both sides. Then we are just going to tighten down the nuts on the outsides. And then we are going to torque them as specified in the instructions. OK, so we are going to take a couple measurements for you now. From the center of the hitch pin hole to the edge of the bumper is going to be approximately 3-1/4 inches. And then from the ground to the top of the receiver tube opening is going to be approximately 12-1/4 inches. That will conclude the installation for part number 24706 on this 2002 Honda Civic.
