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.

This video is to bring you a closer look at the ASI 0755-SS18 18″ Towel Bar.
This item consists of three components, first you’ll have your steel tube (18″).
There is a link below this video to the cut sheet with everything important.
This is stainless steel.
You will also have two wall flanges (these are not the same).
One flange has a set screw and that is intended for holding the bar on (alan wrench style set screw).
Heavy duty stainless steel, type 818-304, 1″ diameter, 20 gauge.
You’ll have your two counter-sunk flanges.
This is really a substantial item.
This is something you would see in a nursing home, hospital, commercial sort of hotel application.
The bar is 1″ diameter.
The flanges have a projection of 2-1/2″ to the center line which would put the overall at about 3-1/16″.
The mounting plate diameter is 2-5/8″.
Center line is 2-1/2″.
The bar is 18″ (measured from center to center).
Screws are NOT included, you’re going to have to provide fasteners for your three counter sunk holes (round head style screw).
There is a guide to the installation on the cut sheet (link below this video).
54″ maximum above the finished floor for your unit.
If you’re buying multiple bars at once be careful not to use all your mounting brackets with the set screws, you only get one per each bar.
If you have any questions on the ASI 0755-SS18 18″ Towel Bar or any other product by ASI please feel free to reach out to us.
