Our grade 8 threaded rods vary in length from 10 to 52 depending on the diameter of the rod. Grade 8 steel threaded rods are about 25 stronger than medium strength steel rods.

About half the strength of medium strength steel threaded rods use these for light duty hanging mounting and fastening. Both specifications are heat treated and tempered at 800 f which creates a very strong part but increases brittleness more than comparative specifications. Coupler nuts also allow you to connect two threaded rods. Made from grade 8 steel they re about 25 stronger than medium strength steel coupling nuts.
