Simpson Strong-Tie© introduces MASA Mudsill Anchors with a new and improved design that provides one-to-one replacement of 1/2-in. and 5/8-in. anchor bolts. The load capacity of the new MASA mudsill anchor meets or exceeds that of other cast-in-place anchors.

Key areas of the anchor have been reinforced and fasteners have been added. In addition, since the MASA can be installed as wide as 6 ft on center, the same load capacity can be achieved with fewer mudsill anchors.

MASA mudsill anchors attach easily to concrete forms and lay flat on top of the form board, eliminating the need to finish around anchor bolts. There is no plate drilling required and the flat design helps avoid time-consuming modifications to prefabricated walls or rim joists that often have to be adjusted to remedy off-center bolt installations. The MASA also eliminates the need for 3-in. square plate washers, which is now required for use with all sill bolts.
