Each type is designed for a specific application. Among these types are Cast-In-Place, Drilled In, Friction, Clamping, Compression, Undercut and Bonded Anchors.The heavy duty is a sleeve style undercut anchor which is vibration resistant and removable. It uses a regular grade 5 hex head bolt for strength. Available with a finished hex head or flat head with a hex key insert, they can be used in concrete, block, brick, or stone. Stocked in diameters from 1/4" to 3/4" and lengths from 1 3/4" to 8 1/4".Approvals:●Listed by Underwriters Laboratories (UL) Listed, EX2224(N)●NY Board of Standards and Appeals●Meets or exceeds U.S. Government G.S.A. Specifications FF-S-325 Group 11, Type 4, Class 1Applications: Light to heavy-duty into solid concrete. Installation:●Drill a hole in the concrete using a hammer drill and a carbide tipped masonry drill bit conforming to ANSI B94, 12-77, the same diameter as the wedge anchor. If the fixture being fastened is in place and being used as a template to locate the hole for the anchor, the mounting hole in the fixture should afford clearance for the universal wedge clip on the stud.●Clear the hole of all debris, then place the wedge anchor through the hole in the fixture or directly into the concrete, and hammer it in to the drilled hole, ensuring that they are installed to the desired depth.●Turn the nut by hand until the unit is "snugged up". Tighten the nut with a torque wrench to ensure they are tightened to the required torque value.
