HeadLok Fasteners are the standard for structural header connections in a Post Frame Precision Pole building. Many companies will use only nails to fasten headers to posts in their buildings. This connection is particularly important to supporting the buildings truss system and roof. Though smaller in size, HeadLok's have higher engineering design values for shear strength and pullout than a 3/8" lag screw. When there is a few feet of snow on your roof you won't have to wonder if just nails were enough. Check out the information below on HeadLoks!
