  • Securing beam to beam joints, joists to joists and jacks to TG trusses.

APPLICATION

The Multinail Joist Hanger is available with or without bolt holes, allowing you flexibility in fastening the Joist Hanger to the truss or beam using nails and/or bolts.

Joist Hangers are easy to install. Simply use 5/30mm x 2.8Ø Multinail galvanised nails, through each wing to secure the Joist Hanger to the supporting member. Alternatively, use one M12 bolt, with washer, in each wing to secure to the supporting member.

To secure the joist or truss to the Joist Hanger, use 3/30mm x 2.8Ø Multinail galvanised nails through each wing.

LIMIT STATE DESIGN LOADS

The following table gives the recommended Limit State Design capacities for Multinail Joist Hangers. Design capacities are for use in limit state design procedures to AS1720.1-2010

NOTE: The capacities are derived from AS1720-2010 and are for uplift in houses where failure is unlikely to affect an area greater than 25m2. For primary elements in structures other than houses or elements in a house for which failure would be greater than 25m2 these capacities must be multiplied by 0.94. For primary joints in essential services or post disaster buildings multiply by 0.88.
