Stitch-Tie Stainless Steel Masonry Pinning System - Box of 50 (10mm)

Stitch-Tie Stainless Steel Masonry Pinning System — Fast, Dry-Set Veneer Re-Anchoring and Crack Stitching

The Stitch-Tie is a Type 304 stainless steel helical pinning system engineered for re-anchoring existing masonry veneers to backup structures and for crack-stitching damaged brick walls. Designed for masonry contractors and restoration professionals, it eliminates the need to tear down and replace existing facades, preserving the architectural and historical integrity of the building. The spiral-shaped tie is driven into a pre-drilled pilot hole using a dry-set tool mounted on a rotary hammer SDS drill — no epoxy, adhesive, or hole cleaning required.

Unlike conventional anchor systems that can draw wythes together and introduce unwanted tension, the Stitch-Tie's helical geometry provides a flexible in-plane connection that resists out-of-plane loading in both tension and compression without adding tension forces between wythes. Installed repairs are concealed in small pilot holes that are easily patched, leaving virtually no visible scar on the facade.

Technical Specifications

Key Features & Benefits

Dry-Set Installation — No Epoxy or Adhesive Required

The Stitch-Tie threads itself into the building material using the percussion action of a rotary hammer, eliminating the cost and time associated with adhesives or epoxies. Pilot holes require no cleaning before installation, further reducing labor time on the job site.

No Tension Added Between Wythes

The helical design does not draw masonry wythes together, so no tension forces are introduced between the veneer and backup structure during installation. This is a critical advantage over systems that can stress or crack already-compromised masonry during the anchoring process.

Nearly Invisible Repairs

Stitch-Ties are installed in relatively small pilot holes that are easily patched and concealed, leaving no exposed hardware on the facade. The setting tool automatically recesses the tie into the face of the masonry, so the repair blends into the existing surface.

All-Weather Capability

Because the system is dry-set with no adhesives or epoxies, installation is not dependent on temperature windows or cure times. Crews can work in any weather condition without waiting for favorable conditions or worrying about adhesive failure.

Helical Design Provides Flexible In-Plane Connection

The spiral shape creates a ductile, flexible connection between wythes that accommodates minor movement without cracking the surrounding masonry. It simultaneously maintains a threaded connection that resists out-of-plane loading in both tension and compression.

Broad Material Compatibility and Versatile Sizing

Available in multiple diameters and lengths, with field-trimming capability, the Stitch-Tie adapts to a wide range of wall assemblies and cavity widths. It can be used on brick, stone, CMU, precast concrete, clay tile, wood, metal studs, and more.

Common Applications

Re-Anchoring Existing Masonry Veneers

The Stitch-Tie is specifically engineered to reattach brick, stone, or masonry facades that have missing or corroded original wall ties, restoring structural connection without requiring demolition of the existing veneer.

Crack Stitching in Brick Veneers

Stitch-Ties can repair cracked brick veneers by being driven horizontally in the bed joint, reinforcing the cracked section and preventing further propagation of stairstep or vertical cracks.

Reconnecting Multi-Wythe Brick Walls

In multi-wythe brick construction, the helical tie bridges the cavity between wythes, providing a code-compliant flexible connection that resists differential movement between the inner and outer masonry layers.

Brick Veneer to Concrete Backup

The Stitch-Tie embeds into concrete backup with a minimum 1-1/4" embedment from the face of concrete, providing tension and compression resistance in concrete-backed veneer assemblies.

Brick Veneer to CMU Backup

For hollow or solid CMU backup structures, the tie provides effective embedment through the face shell into the CMU core, with sizing options to accommodate lightweight and normal-weight block configurations.

Brick Veneer to Wood or Metal Stud Backup

The Stitch-Tie can anchor masonry veneers to wood stud or metal stud (16-gauge) backup framing, with minimum embedment depths of 1-1/2" to 3" into the stud member.

Application Instructions

Preparation: Selecting the Right Stitch-Tie

1. Determine the backup structure material and cavity width to select the correct anchor diameter (8mm or 10mm) and length. Anchor length equals total embedment depth including veneer thickness, cavity, and minimum embedment into backup.
2. Consult the drill bit sizing chart to select the correct pilot hole diameter for the facade material and anchor size combination. Pilot hole depth must exceed anchor length by a minimum of 1" (or 1/2" minimum for wood or metal stud backup).
3. Stitch-Ties can be field-trimmed with cutters to achieve optimum length for the specific installation.

Step 1 — Drill the Pilot Hole

1. Using a percussion hammer drill (3-jaw chuck type), drill a pilot hole through the mortar joint of the outer wythe (preferred entry point) or through the brick face if mortar quality is questionable.
2. Drill to the required depth based on anchor length and backup material. No hole cleaning is required.

Step 2 — Load the Setting Tool

1. Insert the Stitch-Tie into the dry-set installation tool (heavy-duty spring-loaded or economy setting tool) mounted on a rotary hammer SDS drill.

Step 3 — Drive the Stitch-Tie

1. Drive the Stitch-Tie into the pilot hole using the rotary hammer. The percussion action threads the helical tie into the building material.
2. Continue driving until the nose of the setting tool is hard against the veneer face.

Step 4 — Recess and Patch

1. The dry-set installation tool automatically recesses the Stitch-Tie into the face of the masonry.
2. Patch the pilot hole with appropriate mortar or patching material to conceal the repair.

Frequently Asked Questions

Q: Does the Stitch-Tie require epoxy or adhesive to install?
A: No. The Stitch-Tie is a dry-set system — no epoxy, adhesive, or hole cleaning is required. The percussion action of the rotary hammer drives the helical tie and threads it directly into the building material.

Q: Will the Stitch-Tie pull masonry wythes together and add stress to the wall?
A: No. The Stitch-Tie does not draw walls together, so tension forces between wythes are not present. This makes it suitable for anchoring existing, potentially compromised masonry without adding new stress.

Q: What drill is required to install the pilot hole?
A: A percussion hammer drill with a 3-jaw chuck is required for drilling the pilot hole. A separate rotary hammer SDS drill is used with the dry-set setting tool to drive the Stitch-Tie.

Q: What is the typical anchor spacing for veneer re-anchoring?
A: Unless otherwise specified, one anchor per 2 square feet of veneer area is the typical starting point. Always refer to local building codes and standards for spacing requirements applicable to your specific project.

Q: Can Stitch-Ties be used for crack stitching as well as re-anchoring?
A: Yes. In addition to re-anchoring veneers to backup structures, Stitch-Ties can repair cracked brick veneers by being driven horizontally in the bed joint to reinforce the cracked section.

Q: Can the Stitch-Tie be trimmed in the field if the standard lengths don't match the required embedment?
A: Yes. Stitch-Ties can be field-trimmed using cutters to achieve the optimum length for a specific installation condition.
