Staples 140/12

Stronghold® 140-12S Type 140 Flat-Wire Staples (12mm / Box of 5,000)

Zinc-coated flat-wire staples manufactured to the industry-standard Type 140 format. Featuring a deep 12mm shank, they are designed to secure thick insulation, multi-ply corrugated board, carpet underlay, and heavy weatherproof sheeting into timber and composite substrates.

Key Features:

• Deep 12mm Leg Length: Provides substantial penetration depth into timber crates, battens, and pallets to hold bulky or compressible materials firmly in place.

• Type 140 Flat-Wire Profile: Wide wire surface area presses flat against materials, resisting tear-through when fixing thin foils, plastic vapour barriers, or shipping documents.

• Corrosion-Resistant Coating: Zinc-galvanised finish protects against surface oxidisation in damp packing areas, site storage, and transit.

• Standard Stick Strips: Glued collation feeds reliably through compatible heavy-duty hand guns and impact hammer tackers.
