1. The ultimate tension and shear values are for fasteners only. Steel or wood members connected to the substrate must be investigated for compliance with the applicable code.
2. The values listed above are ultimate load capacities which should be reduced by a factor of safety to determine the allowable working load. For allowable load
capacities, see the allowable load tables.
3. Fasteners must be driven to obtain an embedment equivalent to the nominal steel thickness with the point of the fastener penetrating through the steel base material.
4. Multiple fasteners are recommended for any attachment for increased reliability.

1. The allowable tension and shear values are for fasteners only. Steel or wood members connected to the substrate must be investigated for compliance with the applicable code.
2. The values listed above are allowable load capacities. The values are based on minimum required factors of safety. Consideration of additional safety factors may be necessary depending
on the application, such as life safety or overhead.
3. Fasteners must be driven to obtain an embedment equivalent to the nominal steel thickness with the point of the fastener penetrating through the steel base material.
4. Multiple fasteners are recommended for any attachment for increased reliability.

1. Successful fastening to the face shell of Hollow CMU is typically done with the lightest powder load level.
2. The values listed above are ultimate load capacities which should be reduced by a factor of safety to determine the allowable working load. For allowable load capacities, see the
allowable load tables.
3. Multiple fasteners are recommended for any attachment for increased reliability.
4. Concrete masonry units are typical 8 x 8 x 16 inch units meeting the requirements of ASTM C90, Grade N, lightweight block.
