For the construction trade, plastic shims are an essential tool but care must be taken to assure they are rugged enough for the intended use. Before even considering the compressive strength of a plastic shim you must first ensure that is it should be solid with uniform plastic throughout. Lower cost hollow plastic shims are manufactured but do not deliver the strength or durability required for most construction projects.

Hillside Washers are used when connecting braces that pass through structural members at any angle other than 90°. Unlike inside connections requiring Clevis Rod Assemblies (Fig.1), when the brace passes through the structural member it eliminates the need for Clevises and Clevis Pins.

Stainless Steel Turnbuckle Rods and Clevis Rods have some variations in material that will affect the design and production. The first point to note is the difference in material between the round bar and the hardware. Stainless steel round bar comes in a wide variety of grades. For Structural and Miscellaneous steel fabricating the fundament grade is 303 or 304. Often Clevis Rod and Turnbuckle Rod assemblies are specified leaving the fabricator the option of using either.

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.

The steel wedge is an extremely important aspect of any construction process. Another way to understand the power of the steel wedge is by understanding the structural bolt. At first, it might seem as though that the two products have nothing in common, but in reality they are the same thing.

The charts below show the results of tests that were performed on our wedge inserts on October 23, 2007. As a note, these results are for reference only. This is not a test of wedge inserts currently in stock and should not be considered as an accurate representation of the current wedge inserts in stock.

Slide bearings are a very important aspect of the construction process, but the jargon involved can often be very confusing. There are some basic terms that need to be understood when discussing the methods of constructing a Slide Bearing or Teflon® Bearing Pad. The many different terms associated with slide bearing surface are listed below, while next week’s article will cover backing plate options.
Steel Wedges are among the most basic and yet unique products our steel fabricating customers use. They are used for almost everything, from separating heavy plates in the shop, to with an erector lift for extremely heavy objects, to shimming stair stringers.

In the case of relieving angles, the typical shim requirements used are almost always require a single slotted. The stock version of this is 3” wide.
