Lag Shield Anchor Technical Information
Technical information is important when using and installing lag shield anchors. These anchors meet industry standards and also come in a number of sizes to meet all project needs. Lag shields can be used in concrete weights of up to 6,500 lbs. Hole size and embedment also need to be considered when using concrete lag shield anchors due to the wide range of anchor sizes available.

| Values shown are average ultimate values and are offered only as a guide and are not guaranteed. A safety factor of 4:1 or 25% is generally accepted as a safe working load. Reference should be made to applicable codes for the specific working ratio. Minimum embedment for satisfactory anchor performance is 4-1/2 bolt diameters. Deeper embedments will yield higher tension and shear capacity. | |||
