The Simpson MASAZ MASA 16-Gauge ZMAX Galvanized Mudsill Anchor by Simpson is a high-performance mudsill anchor engineered as a time-saving alternative to traditional anchor bolts. Designed specifically for installation on standard concrete forms, the MASA anchor delivers greater load-carrying capacity as an alternative for 5/8-in. and 1/2-in. mudsill anchor bolts on 2x, double-2x, and 3x mudsills. It eliminates the need for 3-in. square plate washers for seismic design and, in some cases, offers load capacities that meet or exceed the parallel and perpendicular to plate shear capacity of other cast-in-place anchors. The ZMAX galvanized finish provides enhanced corrosion resistance, making this anchor well-suited for exterior and treated-wood applications.

Key Features

• Attaches easily to the concrete form for quick installation
• Lays flat on the form board so there is no anchor bolt to finish around
• No labor costs involved in drilling plates and aligning holes
• Flat design eliminates chances of modification in prefabricated walls
• Eliminates the need to notch studs due the anchor bolts being placed where it will interfere
• Reduces the chance of having to retrofit anchors because of missing or misplaced anchor bolts
• Minimum MASA end distance is 4 in. and minimum center-to-center spacing is 8 in. for full load
• Made from 16-gauge steel
• ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications
• Install with 0.148 in. x 1-1/2 in. nails

Frequently Asked Questions

What is the difference between the MASA and the MASAP?

Two versions of the MASA are available - the standard MASA for installation on standard forms and the MASAP for panelized forms. The MASAZ is the ZMAX-finished version designed for use with standard forms.

What nail size should be used to install the MASAZ?

The MASAZ should be installed with 0.148 in. x 1-1/2 in. nails.

What are the minimum spacing and end distance requirements for full load capacity?

The minimum MASA end distance is 4 in. and the minimum center-to-center spacing is 8 in. for full load.

Why is the ZMAX finish recommended for this mudsill anchor?

ZMAX galvanization offers extra corrosion resistance, making the MASAZ well-suited for exterior and treated-wood applications where standard galvanized coatings may not provide adequate protection.
