Description

The HILLMAN FASTENERS 461397 is a 16D bright duplex nail designed for temporary fastening applications in construction and formwork. Measuring 3 inches in length, this nail features a double-head design that allows for easy removal after concrete forms, scaffolding, or other temporary structures are no longer needed. The bright finish indicates an uncoated steel construction suited for dry, interior, or short-term exterior applications. Sold in a 5-pound box, this is a standard trade-quantity format familiar to framing crews and concrete contractors.

Duplex nails are a common consumable on commercial and residential job sites wherever temporary wood formwork is assembled and later stripped. The double-head design is the defining feature: the lower head seats flush against the work surface while the upper head remains exposed for quick extraction with a cat’s paw or hammer. This makes them a go-to fastener for concrete form panels, temporary shoring, and bracing applications where repeated assembly and disassembly is part of the workflow.

Compatibility

Designed as a standard 16D duplex nail for use with temporary wood formwork, scaffolding, and bracing applications using dimensional lumber.

Installation Notes

Duplex nails are driven by a framing hammer or pneumatic nailer capable of accepting duplex-style fasteners. Drive until the lower head is seated against the work surface, leaving the upper head exposed for later removal. When stripping forms, use a cat’s paw, flat bar, or hammer to pull from the exposed upper head. Always follow applicable safety and fall-protection codes when working on elevated formwork or scaffolding.
