These 8mm heavy duty staples (box of 1000) are U‑shaped, smooth wire fasteners with an 8mm leg length designed for use in hand operated heavy‑duty staplers and tackers. Their primary use is to fix thin sheet materials, fabric, insulation, felt, underlay and light joinery components to timber, plywood and engineered board where a short, strong clinch is required without a protruding head.

Each staple is formed from cold‑drawn carbon steel wire and supplied with a bright zinc plate finish to resist surface corrosion in indoor and semi‑exposed environments. The staples are supplied as standard crown width items to suit common heavy‑duty hand staplers (compatible with Draper/DR13955 style workshop staplers); they are smooth‑leg staples without thread, head or drive features, designed to produce a reliable clinch when used with a matching anvil. For applications requiring enhanced corrosion resistance, stainless steel (A2/304) alternatives are available to order.

There is no single DIN/ISO/BS standard that covers all general‑purpose hand staples; these fasteners are manufactured to industry workshop tolerances and to fit the dimensions and feed mechanisms used by mainstream heavy‑duty hand staplers. Material and finish conform to standard practice for fastening consumables used in building and upholstery trades, ensuring consistent leg length and crown geometry for reliable feeding and reduced misfires.

Typical applications include upholstery and furniture assembly, fixing roofing felt and underlay, securing insulation and vapour membranes, temporary fixtures in joinery, and general workshop or packaging tasks. The benefits of these staples include good corrosion resistance from the zinc finish, sufficient shear and clinch strength for light to medium fastening tasks, and compatibility with a wide range of hand tacker models used in workshops, maintenance and site work.

Duchy Fasteners supplies these 8mm heavy duty staples in boxes of 1000 and stocks a range of leg lengths and crown widths to suit different staplers and applications; small trade packs and bulk cartons are available on request.
