The Torq-Lok® 520 Series Anchor for stud backup, features 360 Brass expanders with Type 304 St/Steel shaft and 300 St/Steel hardware. Can be used with metal stud or structural steel.
The Torq-Lok® mechanical anchoring system is an easy to use and cost-effective method to re-connect existing veneers to various substrates. The process eliminates the need to tear down an existing veneer by providing a corrosion-resistant tie assembly. They are torque-activated which provides a method of inspection for both the façade and backup connection.
Once installed, the anchors resist veneer loading in both compression and tension. The design of the system provides two independently activated expanders that do not create tension between wythes. All Torq-Lok® anchors are installed at “T” joint or bed joint locations, concealed with a mortar patch or sealant, and have no exposed hardware.
Use where facades have missing or corroded wall ties or anchors. Can be applied at peripheral areas that are bulging or around areas that are to be removed. Use as a replacement tie for broken or cracked headers in composite walls. Use in high stress areas, which require load resistance greater than provided by typical wall ties. Can also be applied or modified to re-attach thin clad stone to various backup materials.
