The Simpson HM9KT HM9 Hurricane Tie Kit from Simpson is an 18-gauge galvanized connector kit engineered to resist high winds and seismic forces by positively connecting trusses and rafters to the top of wall structures. Designed specifically to retrofit roof truss and rafter assemblies for block construction, the HM9 delivers high uplift and lateral capacity using Titen Turbo concrete and masonry screws. Compatible with both solid-sawn and engineered lumber across a wide range of structural applications, this kit arrives with all necessary fasteners included - so installation can begin without sourcing hardware separately.

Key Features

• Complete, ready-to-install kit - includes (20) HM9 connectors, (80) 1/4 in. x 1-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws, and (100) 1/4 in. x 2-1/4 in. Titen Turbo screws, eliminating the need to purchase fasteners separately and keeping your crew productive on site.
• 18-gauge steel construction - provides the structural rigidity needed to maintain secure roof-to-wall connections under high uplift and lateral load conditions.
• G90 zinc galvanized finish - delivers extra corrosion resistance, making these hurricane ties well suited for demanding environments where long-term durability matters.
• Broad lumber compatibility - works with both solid-sawn and engineered lumber, giving installers flexibility across a wide range of framing applications without needing different connector types.
• Titen Turbo screw compatibility - engineered to anchor directly into concrete and masonry substrates, making these ties a practical solution for block construction retrofit projects requiring reliable uplift resistance.

Why This Product

• Everything in one box - the HM9KT bundles connectors and all required fasteners together, so contractors working on wind or seismic retrofit projects can go straight from delivery to installation without a separate trip to source hardware.
• Built for block construction retrofits - the HM9 is specifically designed to retrofit roof truss and rafter assemblies in block construction, addressing a common challenge where standard ties may not offer the uplift and lateral capacity that masonry-anchored connections demand.
• Trusted engineering for high-load applications - Simpson hurricane ties are purpose-built to resist the forces of high winds and seismic events, providing positive rafter-to-wall connections where structural performance is critical.
• Corrosion-resistant for long service life - the G90 galvanized coating protects the steel connectors against corrosion, helping maintain structural integrity over time in applications where moisture exposure is a concern.
