In an ordinary buttress thread, the weight-bearing flank has a 70-degree slant, while the trailing flank features a 45-degree slant.
Following the concrete hardens, holes are drilled into the Wooden sill plates to match the configuration with the bolts, and then nuts are utilized to firmly protected the plates to the very best from the concrete wall.
