The BON 91-N40D5LB is a 40D common steel nail measuring 5 inches in length, sold in a 5-pound box. Common nails in the 40-penny (40D) size are standard fasteners used in heavy framing, structural connections, and general construction carpentry. The steel construction provides the shear strength and holding power required for load-bearing applications. Each box contains enough nails for extended job-site use without frequent restocking.
These 5-inch 40D nails are suited for residential and light commercial framing tasks where large common nails are specified. Typical applications include rim joist connections, ledger board fastening, stair stringer installation, and similar structural wood-to-wood assemblies. Carpenters, framers, and general contractors keep this size on hand for heavy timber work where smaller fasteners are not appropriate.
Designed as a standard 40D common nail for use in heavy wood framing and structural carpentry applications where 5-inch common nails are specified.
Installation is performed by carpenters and framers using a framing hammer or pneumatic framing nailer rated for 40D common nails. Always verify that the fastener size and spacing meet local building code requirements and applicable structural specifications before installation. Store nails in a dry location to prevent surface oxidation that could affect performance.
