ST Foundation Anchors
ST1-TZ – For installation into concrete slab or poured stemwalls.
The ST1-TZ features a prebent base ange to assure proper anchoring
into concrete. For concrete/masonry installations, refer to the FA & ST Foundation
Anchors Technical Bulletin.
ST2-TZ – For installation into concrete slab, poured stemwalls or concrete/masonry.
The ST2-TZ features a prebent base ange to assure proper anchoring into concrete.
Materials: 18 gauge
Finish: G-185 galvanizing
Codes: See page 11 for Code Reference Key Chart
Installation:
• Use all specied fasteners. See Product Notes, page 17.
• Use a minimum of two anchors per mudsill. An anchor should always be within 12"
of the end of each mudsill section. Follow spacing guidelines in chart.
• Do not rely on these anchors to secure concrete sections together between cold joints.
• Spread sill anges to mudsill width prior to insertion into wet concrete (minimum
strength of 2,500 psi). Alternate installation is possible by inserting unbent anges
through 3/4" center hole pre-drilled in mudsill. Foundation anchors may also be
attached to mudsill and then inserted into wet concrete. When installing ST2-TZ into
concrete block, ll cells with grout with a minimum strength of 2,500 psi. Concrete
block edges may need to be beveled to facilitate installation.
• For additional installation details and information on mudsill anchors refer to
ST Foundation Anchors Technical Bulletin.
• ST2-TZ in masonry construction shall be installed in the core of the block and grouted
with concrete grout designed for that purpose. In no case, shall they be installed in a
mortar joint.
• Do not use in red clay brick.
