Joist hangers are designed to provide support underneath the joist, rafter or beam to provide a strong a connection. Simpson Strong-Tie offers a diverse line of hangers to handle almost any application with top flange, concealed flange and field-skewable and slopeable options. All hangers in this series have double-shear nailing — an innovation that distributes the load through two points on each joist nail for greater strength. This allows for fewer nails, faster installation, and the use of all common nails for the same connection. MUS Galvanized Face-Mount Joist Hanger for 2×6 (Pack of 1500).
