Configurations
There are two types of rods which are commonly used in the lighting industry: thread-each-end rods and fully threaded rods. Anchor rods are embedded into the concrete with large templates to provide pullout resistance and proper spacing for the anchor bolts to match the base of the light pole or traffic signal. Depending on the style of the pole, the base plate for the pole will have a bolt pattern which the anchor rods must align with for a perfect fit. This is why many anchor rod assemblies for the lighting industry are sold with bolt templates or template straps to match the configuration of the base plate on the pole.
If the pole base has a triangular bolt pattern, the rods will commonly have 6 nuts, 2 washers and 2 template straps per rod. For circular and square bolt patterns, anchor rods commonly have 6 nuts and 6 washers per rod with 2 templates per set of anchor bolts (1 set = 4 anchor rods).
Grades
Anchor rods for the lighting industry are most commonly manufactured in two grades of the F1554 specification, Grade 55 and Grade 105. However, they are also manufactured in Grade 36 and A449, as well as other grades depending on the situation. Portland Bolt keeps a variety of WSDOT and ODOT standard anchor rods in stock and these sizes can be found below.
Common Sizes
The following tables show the available stock parts at Portland Bolt. These tables give an idea of what sizes and configurations of light pole anchor bolts are readily available. Nonstandard light pole anchor bolts in virtually any ASTM grade, size, and configuration can be manufactured with very short lead times.
