Clevis and Turnbuckle Assemblies
Clevis and Turnbuckle Assemblies are produced at The Steel Supply Company as part of our Round Bar Threading and Anchor Bolt manufacturing process.
If you were just starting out as a structural steel fabricator, it wouldn’t be long before you saw a tie rod, hanger rod, or cross brace assembly called for on a building plan. Typically, these assemblies are used in conjunction with a clevis, or more commonly two clevises, and a turnbuckle. While we go into depth on tie rods, clevises and turnbuckles in other articles, today we are focusing on a particularly unique clevis rod order that The Steel Supply Company fulfilled.

The Clevis Rod and the Turnbuckle Rod offer the ability to provide tensile strength by increasing their tension as they are tightened. The tightening is done by opposing left hand and right hand threads. In the Clevis Rod drawing shown below rotating the threaded rod overhand towards the installer it will draw the two Clevises closer, creating more tension. Rotate the Rod overhand away from the installer will move the clevises away from each other, relieving tension.

Expanding on the blog post from April 2015, there are two features unique to the Hillside Washer that allow it to function. The Locking Tab and the Spheroid Shape.

Grinnell Standards are a way of limiting the variables when designing a clevis rod or turnbuckle rod. While clevis rods and turnbuckle rods can be manufactured in any diameter and set of specifications, keeping it simple is always desirable for the structural steel fabricator. The main structural concern is tensile strength. Round bar diameter is the primary feature that controls tensile strength and the remaining components are designed around that.

For most fabricated structural and miscellaneous steel, hot dip galvanizing is a fairly basic process. The galvanizers follow the applicable specification, usually ASTM A123 / A123M, or the corresponding AASTHO spec. As most steel members or finished assemblies are stationary, excess zinc is not a problem.
