Single Expansion Anchor Technical Information
There are technical requirements that need to be considered when installing single expansion anchors. Anchor size, anchor length, as well as hole size and bolt diameter need to be considered when using concrete expansion anchors. Anchors can be used in concrete ranging from 800lbs. to 2400lbs. A single expansion anchor uses a standard machine threaded bolt or screw.
| Anchor Size | Anchor Length | Hole Size | Bolt Diameter | Concrete |
| 1/4" | 1-5/8" | 1/2" | 1/4" | 800 lb. |
| 5/16" | 2-1/8" | 5/8" | 5/16" | 1100 lb. |
| 3/8" | 2-1/8" | 5/8" | 3/8" | 1460 lb. |
| 1/2" | 2-5/8" | 7/8" | 1/2" | 1860 lb. |
| 5/8" | 3-1/8" | 1" | 5/8" | 2400 lb. |
| 3/4" | 2-3/4" | 1-1/4" | 3/4" | 4400 lb. |
| 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 embedment will yield higher tension and shear capacity. | ||||
