- 303 and 304 stainless steel – for use in applications where moisture is present in the atmosphere or where the wedge anchor is submerged in water.
- 316 stainless steel – for use in applications submerged in water or in other chemicals such as chlorine.
- Diameters – 1/4”, 5/16”, 3/8”, 1/2”, 5/8”, 3/4”, 7/8”, 1” and 1-1/4”.
- Lengths – range in length from 1-3/4” to 12” depending on the diameter.
The diameter of the hole to drill in the concrete is equal to the diameter of the wedge anchor being installed.
The bit diameter is equal to the diameter of the stainless steel wedge anchor being installed and must meet ANSI standards.
Type of Drill
A hammer drill must be used in the hammer and rotation mode when drilling the hole in the concrete.
When stainless steel wedge anchors are purchased from www.confast.com, they will be packaged with the correct type, size and quantity of nuts and washers each and every time.
Length of Anchor to Use
Determine the minimum length of the anchor by adding the thickness of the material being fastened plus the minimum embedment for the diameter of the anchor being installed plus the space for the nut and washer.
Diameter to Use
The diameter of wedge anchor to use is determined by the amount of weight required by the particular application. The more weight that is required will mean a larger diameter of stainless steel wedge anchor should be used. The large diameter wedge anchor has better holding values for shear, and the larger the diameter then the deeper the embedment in the concrete will be to provide better pullout values.
Where to Purchase
Concrete Fastening Systems, Inc carries a complete line of 303 and 316 stainless steel wedge anchors with every size in stock and ready to be shipped from the Cleveland, Ohio warehouse the same day the order is received. Each size of stainless steel wedge anchor is packaged with the correct size and type of nut and washer.
Cost of Stainless Steel
As a rule of thumb, the 303/304 stainless steel runs two to two and a half times the cost of standard zinc plated carbon steel. The 316 stainless steel runs about two times the cost of 303/304 stainless steel.
