The Simpson MASAZ Mudsill Anchor for Standard Forms is a 16-gauge steel anchor engineered as a time-saving, high-capacity alternative to traditional anchor bolts when connecting mudsills to concrete foundations. Designed for installation on standard concrete forms, it supports 2x, double-2x, and 3x mudsills and serves as a direct alternative for 5/8-in. and 1/2-in. mudsill anchor bolts. The flat, form-mounted design streamlines the framing process from the ground up, while the ZMAX galvanized finish delivers enhanced corrosion resistance that stands up to exterior conditions and contact with treated wood.

Key Features

• Attaches easily to the concrete form for quick installation - reduces time spent on anchor placement compared to setting traditional anchor bolts, keeping your pour schedule on track.
• Lays flat on the form board with no anchor bolt protruding - eliminates the finishing work typically required around bolt heads, resulting in a cleaner slab surface.
• No drilling of plates or aligning of holes required - removes a labor-intensive step from the mudsill attachment process, cutting overall installation costs.
• Flat profile eliminates chances of modification in prefabricated walls - the low-profile design fits seamlessly into prefab wall systems without requiring field adjustments.
• Eliminates the need to notch studs caused by mispositioned anchor bolts - anchors are positioned correctly from the start, preserving stud integrity and structural performance.
• Reduces the chance of retrofitting anchors due to missing or misplaced bolts - the form-attached method keeps anchors exactly where they need to be before the pour, avoiding costly after-the-fact corrections.
• Eliminates the need for 3-in. square plate washers in seismic design - simplifies hardware requirements and reduces material costs on seismic-zone projects.
• Load capacities that can meet or exceed parallel and perpendicular to plate shear capacity of other cast-in-place anchors - delivers structural performance without relying on supplemental hardware.
• Made from 16-gauge steel - provides the rigidity and strength required for reliable mudsill-to-foundation connections in residential and light commercial framing.
• ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications - performs where standard coatings fall short, making it appropriate for chemically treated lumber and moisture-exposed environments.

Why This Product

• A faster, cleaner alternative to anchor bolts - the form-mounted, flat design eliminates bolt protrusion, plate drilling, and hole alignment, replacing several labor-intensive steps with a single streamlined anchor that attaches directly to the form before the pour.
• Built for seismic and high-demand applications - the MASAZ can eliminate the need for 3-in. square plate washers in seismic design and, in some cases, matches or exceeds the shear load capacity of other cast-in-place anchor systems, making it a structurally capable choice for demanding projects.
• ZMAX finish for long-term durability in tough conditions - the ZMAX galvanized coating provides a higher level of corrosion protection than standard finishes, making this mudsill connector well-suited for use with pressure-treated lumber and exterior foundation applications where moisture exposure is a real concern.
• Reduces risk of costly field corrections - because the anchor is secured to the form prior to the concrete pour, it significantly lowers the likelihood of missing or misplaced anchors that would otherwise require expensive retrofitting or stud notching after framing begins.
