A joist hanger is a piece of hardware that makes joist installation simpler. The joist hanger also adds reinforcement to the joist. A joist is a sort of cross beam that reinforces the weight capacity of a deck. To properly install a joist and joist hanger, you must use precise nails. Driving the nails exactly is necessary in both the hanger and joist assemblies to maximize the pair's weight capacity.
Things You'll Need
- 10d galvanized nails
- 16d galvanized nails
- 1.5-inch galvanized joist hanger nails
Toenail the joist to the wall ledger using 10d to 16d galvanized nails. Toenailing is when you hammer the nail in at a 45-degree angle, so that the nail attaches to both the joist and the wall ledger at the same time.
Slip the joist hanger onto the joist from the bottom, so that the joist sits in the inside part of the U shape of the hanger. The two face flanges of the joist hanger should be flush with the wall ledge. The face flange on a hanger flares out away from the U-shaped center.
Nail the joist hanger onto the wall ledger by hammering in a 16d galvanized nail at the top and bottom of each of the face flanges. The nail must go into the joist hanger face flange and the wall ledge straight.
Nail the joist hanger onto the joist by toenailing a 10d galvanized nail at the top and bottom of each of the joist flanges. The joist flanges are the part of the U-shaped hanger that hugs the joist. If you don't have a double-shear joist hanger, then skip this step.
Hammer in a 1.5-inch galvanized joist hanger nail at the top and bottom of each of the joist flanges to attach the hanger to the joist. If you don't have a standard hanger, then skip this step.
