Value Collection 12DUP5 12D Duplex Nail 3.25 in Smooth Shank

Product Description

The VALUE COLLECTION 12DUP5 is a 12D duplex nail designed for temporary fastening applications in concrete formwork, scaffolding, and bracing assemblies. At 3.25 inches overall length and manufactured from Grade 2 steel, this nail features a smooth shank and a double-headed (duplex) profile that allows easy extraction after the temporary structure is removed. The 9-gauge wire diameter provides adequate holding strength during use while the raised secondary head makes removal straightforward without damaging surrounding material. Carpenters and concrete form workers are the primary installers of this fastener type.

Duplex nails see the most use on job sites where formwork, shoring, and temporary bracing must be assembled and then disassembled cleanly. The double-head design lets the nail seat fully against the form material while leaving the upper head exposed for claw-hammer or pry-bar removal. This makes them a standard choice on residential foundation pours, commercial concrete deck forms, and temporary support structures across light to heavy construction applications.

Key Features

• Double-head (duplex) profile allows full seating with easy pry-bar extraction
• 12D penny size at 3.25 inches overall length for standard formwork thickness
• 9-gauge smooth shank for consistent drive and controlled pull resistance
• Grade 2 steel construction provides reliable strength for temporary load-bearing assemblies
• Flat primary head seats flush against form surface during use

Compatibility

Designed as a standard 12D duplex nail suitable for use in wood concrete formwork, temporary bracing, and scaffolding applications where removable fastening is required.

Installation Notes

Duplex nails are driven by qualified carpenters or form workers using a standard framing hammer or pneumatic framing nailer compatible with the appropriate nail gauge and length. Always confirm that the nailer tool accepts duplex-style collated or loose nails before use. When stripping forms, use a pry bar against the upper head to back the nail out cleanly and avoid splintering the form lumber for reuse.
