Ingco 40mm 18-Gauge Narrow Crown Staples - 2500-Piece Heavy-Duty Galvanized Steel Fastener Set for Pneumatic and Cordless Staplers (AST18401)

Securing heavy furniture backing, subfloor plywood sheets, wooden crates, or tongue-and-groove wall panels with weak finishing nails or low-grade fasteners results in loose joints, structural warping, and material splitting under tension. Standard wide-crown staples split delicate wooden moldings, while flimsy pins lack the holding power to clamp dense woods together permanently. The Ingco AST18401 40mm 18-Gauge Narrow Crown Staple Set is an industrial-strength fastening solution engineered to deliver deep structural penetration, maximum shear resistance, and a highly discreet finish. Outfitted with an optimized 5.7mm narrow crown profile, this premium hardware pack allows carpentry contractors, cabinetry fabricators, and upholstery specialists to lock multi-layered wood and composite joints together with absolute speed and efficiency.

The exceptional clamping power and fracture resistance of these crown staples stem from their premium galvanized steel core configuration. Built to handle intense, high-velocity drives from pneumatic and electric tools, each staple strip features precise alignment to ensure smooth feeding without jamming or double-firing inside tool magazines. The 18-gauge thin wire design (1.25mm × 1.0mm) slices cleanly through dense wood fibers without splitting the substrate, while the massive 40mm leg length provides maximum deep-set holding power. Finished with a high-grade zinc galvanized treatment, these staples heavily resist corrosion and humidity, making them perfect for internal framing and covered outdoor assemblies. Supplied as a massive 2500-piece bulk pack, this kit keeps your stockroom fully supplied for continuous high-volume assembly lines.

Key Features

• Deep 40mm Leg Length – Long, heavy-duty structural legs provide exceptional deep-set holding power and superior pull-out resistance in dense materials.

• 5.7mm Narrow Crown Profile – Compact crown width blends cleanly into wood surfaces for a neat, low-profile aesthetic while preventing material split-outs.

• Industrial 18-Gauge Wire – Precision-engineered 1.25mm × 1.0mm dimensions deliver the ultimate trade balance between maximum holding strength and minimal entry visibility.

• Rust-Resistant Galvanized Finish – Treated with an advanced zinc coating to defend the raw steel against oxidation, workshop moisture, and environmental degradation.

• Jam-Free Collation Strips – Tightly bonded, uniform staple rows guarantee flawless mechanical feeding and zero tool cylinder jamming at high operational speeds.

• Bulk 2500-Piece Color Box – Securely packed in a rugged, signature color cardboard box layout for easy stock tracking, clean warehouse inventorying, and safe transit.
