|Simpson H2.5A Hurricane Clip/Tie
The Hurricane Tie series features various configurations of wind and seismic ties for trusses and rafters.
The TSP stud plate tie has now been tested in the top-plate-to-rafter connection.
The H2A features an improved design and higher uplift loads
to replace the H2. The H10A has a similar design as the H10 but offers
higher uplift capacity. The H10S provides a high capacity connection
from truss/rafter to stud.
The H2.5T's truncated design was developed to accommodate trusses
with 2x4 bottom chords. The easy to install, five nail pattern is
stronger and gets better uplift loads than our popular H2.5 hurricane
tie. H1, H10, H10S, H10-2, H11Z and H14 have also been rated for
download to provide additional bearing capacity between the truss and
The pre-sloped 5/12 seat of the H16 provides for a tight fit and
reduced deflection. The H16-2 has a pre-sloped seat of 5/12 for double
trusses. The strap length provides for various truss heights up to a
maximum of 13 1/2". Minimum truss heel height for the H16 series is
The HGA10 attaches to gable trusses and provides good lateral wind
resistance. The HS24 attaches the bottom chord of a truss or rafter at
pitches from 0/12 to 4/12 to double 2x4 top plates. Double shear nailing
allows for higher lateral resistance.
Galvanized. H7Z and H11Z—ZMAX coating. Some models available in stainless steel or ZMAX coating; See Corrosion Information.
- Use all specified fasteners. See General Notes.
- H1 can be installed with flanges facing inwards (reverse of H1 drawing).
- H2.5, H2.5T, H3, H4, H5 and H6 ties are only shipped in equal quantities of rights and lefts. (Rights shown.)
- HGA10KT: sold as a kit with (10) HGA10 connectors. SDS screws are included.
- HS24 requires slant nailing only when bottom chord of truss or rafter has no slope
- Hurricane Ties do not replace solid blocking.
- Do not drive nails through the truss plate on the opposite
side of single-ply trusses, which could force the plate off the truss.
These products are available with additional corrosion protection. Additional products on this page may also be available with this option, check with Simpson Strong-Tie for details.
These models are approved for installation with the Strong-Drive SD Structural-Connector screw
See footnote 13 for correct substitution. .
- Loads have been increased 60% for wind or earthquake loading with no further increase allowed; reduce where other loads govern.
- Allowable loads are for one anchor. A minimum rafter
thickness of 2 1/2" must be used when framing anchors are installed on
each side of the joist and on the same side of the plate (exception:
connectors installed such that nails on opposite sides don’t interfere).
- Allowable DF/SP uplift load for stud to bottom plate installation (see detail 15) is 400 lbs. (H2.5); 390 lbs. (H2.5A); 360 lbs. (H4) and 310 lbs. (H8). For SPF/HF values multiply these values by 0.86.
- Allowable loads in the F1 direction are not
intended to replace diaphragm boundary members or prevent cross grain
bending of the truss or rafter members.
- When cross-grain bending or cross-grain tension cannot be
avoided in the members, mechanical reinforcement to resist such forces
may be considered.
- Hurricane Ties are shown installed on the outside of the
wall for clarity and assume a minimum overhang of 3 1/2" installation on
the inside of the wall is acceptable (see General Instructions for the Installer notes u).
For uplift Continuous Load Path, connections in the same area (i.e.
truss to plate connector and plate to stud connector) must be on same
side of the wall.
- Southern Pine allowable uplift loads for H10A = 1340 lbs. and for H14 = 1465 lbs.
- Refer to technical bulletin T-HTIEBEARING for selected hurricane ties allowable bearing enhancement loads.
- H10S can have the stud offset a maximum of 1" from rafter
(center to center) for a reduced uplift of 890 lbs. (DF/SP), and 765
- H10S nails to plates are optional for uplift but required for lateral loads.
- Some load values for the stainless-steel connectors shown
here are lower than those for the carbon-steel versions. Ongoing test
programs have shown this to also be the case with other stainless-steel
connectors in the product line that are installed with nails. Visit www.strongtie.com/corrosion for updated information.
