Specification Brand : YWNYT BulletPoint1 : Maximum working pressure of 2000 psi, temperature range from -100 to +660 degrees ℉. BulletPoint2 : The concrete anchor is for heavy duty fastening applications where high pull out values in concrete are needed. It is for concrete only, not for block or brick base material. BulletPoint3 : Material: Made from 304 Stainless Steel, can be used in wet, submerged environments and will not rust. BulletPoint4 : Hole Size Is Anchor Size: Drill bit diameter/Hole diameter is the same as anchor diameter. Use a 3/8" drill bit to drill a hole in the base material (Concrete only). BulletPoint5 : The wedge anchor is used in fastening sheet metal, steel and aluminum angles, or wood to concrete.

This anchor is designed for use in Concrete only, and should never be used in block or brick base material. Hole Diameter/Bit Diameter The anchor requires a 1/2" hole to be drilled in the base material (Concrete only). The hole should be drilled with carbide tipped bit that meets ANSI standards and used in a hammer drill. Thread Length The length of the anchor is 4-1/2" Minimum Embedment The minimum anchor embedment into the concrete is 2-1/4". Therefore, the anchor must be installed so that a minimum of 2-1/4" of the anchor is embedded into the concrete. Wrench Size The size of the wrench required to turn the nut to set the anchor is 3/4". Torque Value The maximum torque that can be applied to the anchor once installed is 55 ft./lbs. Spacing between Anchors Each anchor must be spaced a minimum distance of 7-7/8" from each other when measured center to center. Edge Distance It is very important not to install the anchor any closer than 3-15/16" from an unsupported edge of the concrete.
