Choose Dowel Pins by grade and finish, with carbon steel for general work, alloy for strength, and stainless for corrosion resistance, plus zinc and hot-dip galvanized options for the outdoors. Pair them with environmental, fasteners, and Cotter Pins to round out the assembly.

How to Choose

Match the grade to the working load and the finish to the environment after locking in diameter, thread pitch, and length. Harsh or corrosive settings call for alloy or stainless.
