TorkFix

Retrofit mechanical repair anchor

usa_torkfix_picTorkFix mechanical repair anchors are a well proven method of stabilizing masonry veneer walls which have become detached from the inner supporting structure due to wall tie failure or omission at the time of construction. Suitable for tying masonry veneers to inner wythes of brick, concrete block, wood or steel stud, TorkFix retrofit anchors provide structural stability and resist wind pressure forces.

TorkFix anchors are manufactured with a central tie rod, made from austenitic stainless steel Grade 304, approximately 11/64” in diameter to give adequate strength and flexibility. A rubber drip ring prevents water transfer between wythes. The brass expander is made from ASTM G71 brass.

Brick to Brick / Concrete Block / CMU Installation

1. Drill a 7/16” pilot hole through the outer facade, either through the solid brick or mortar joint, and approximately 2 1/2” into the backup material, using a rotary percussion drill (3-jaw-chuck-type).


2. Screw the threaded end of Setting Tool 1 onto the outer end of the anchor and insert fully into the hole in the far wythe.


3. Turn Setting Tool 1 until the inner shell has expanded and is tight. Apply the torque wrench to the end of the Setting Tool 1 (1/4″ square) to check the torque – usually 36lbf-ins for standard brick but may be increased to 54lbf-ins for harder substrates.


4. Fit Setting Tool 2 over the end nut and turn until the outer shell has expanded and is tight (36-54lbf-ins). Fit the torque wrench to the end of Setting Tool 2 (1/4″ square) and check the torque, as before. Make good the hole and seal the surface with color-matched mastic or mortar.

Brick to Wood Installation

1. Drill a 7/16” hole through the outer wythe, either through the solid brick or mortar joint.

2. Screw the threaded end of Setting Tool 1 onto the outer end of the anchor, insert into the hole and screw the anchor into the wood stud to a minimum depth of 11/4“.

3. Fit hexagon of Setting Tool 2 over the end nut and turn until the outer shell has expanded and is tight. Apply the torque wrench to the end of Setting Tool 2 (1/4“ square) to check the torque (36-54lbf-ins). Make good the hole and seal the surface with color-matched mastic or mortar.

4. Fit Setting Tool 2 over the end nut and turn until the outer shell has expanded and is tight (36-54lbf-ins). Fit the torque wrench to the end of Setting Tool 2 (1/4“ square) and check the torque, as before. Make good the hole and seal the surface with color-matched mastic or mortar.

Brick to Steel Installation

1. Drill a 7/16″ diameter pilot hole through the facade, either through the solid brick or mortar joint using a rotary percussion drill (3-jaw-chuck-type)


2. Drill a hole in the steel stud using a 3/16″ drill bit 


3. Screw the threaded end of Setting Tool 1 onto the outer end of the anchor and screw the anchor into the steel stud to a minimum depth of 3/8″


4. Fit hexagon of Setting Tool 2 over the end nut and turn until the outer shell has expanded and is tight. Apply the torque wrench to the end of Setting Tool 2 (1/4″ square) to check the torque (36-54lbf-ins). Make good the hole and seal the surface with color-matched mastic or mortar.

Veneer Panel Anchor Installation

1. Drill a 7/16” pilot hole through the outer panel and approximately 1 1/2” into the backup material, using a rotary percussion drill (3-jaw-chuck-type). The anchor head may be fitted to the outside face of the panel or recessed below the surface. If the head is to be recessed, drill a 3/4″ diameter counter bore into the panel at least 3/16″ deep.


2. Screw the threaded end of Setting Tool 1 onto the outer end of the anchor and insert fully into the hole.


3. Turn the Setting Tool 1 until the inner shell has expanded and is tight. Apply the torque wrench to the end of the Setting Tool 1 (1/4″ square) to check the torque – usually 36lbf-ins for standard brick but may be increased to 54lbf-ins for harder substrates.


4. Fit the nut to the anchor shank and tighten with the 1/4″ Allen key to provide support and seal against water.
