Whether you're a maintenance technician keeping production lines running, a cyclist replacing a worn chain link, or a DIY builder assembling custom drive systems, you need a connecting link that installs fast and holds under load. These stainless steel roller chain connecting links with full buckle closure are engineered for exactly that job.\u003c\/p\u003e\n    \u003cp\u003eEach connecting link consists of a side plate, roller pin, and spring clip (full buckle) machined to match standard ANSI roller chain dimensions. Available in six chain sizes — #25 (04C-1), #35 (06B-1), #40 (08B-1), #50 (10A-1), #60 (12A-1), and #80 (16A-1) — with inner widths and pin diameters sized to match each standard. Constructed from stainless steel for corrosion resistance in wet, outdoor, and chemically exposed environments. Pitch ranges from approximately 6.35 mm (1\/4 in) for #25 up to 25.4 mm (1 in) for #80.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include replacing connecting links on ANSI roller chain conveyor systems, repairing agricultural equipment drive chains, maintaining go-kart or small engine drive chains (#35\/#40), and building custom power transmission assemblies where corrosion resistance is required. Long-tail use cases: stainless steel roller chain master link replacement, ANSI #40 connecting link for conveyor repair, #50 chain joining link corrosion resistant.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits standard ANSI\/ISO roller chains — #25 (04C-1), #35 (06B-1), #40 (08B-1), #50 (10A-1), #60 (12A-1), #80 (16A-1).
