The 04C-1 single row roller chain is engineered for makers, maintenance technicians, and light-industrial builders who demand consistent pitch accuracy and reliable tensile strength in compact drive systems.\u003c\/p\u003e\n    \u003cp\u003eThis chain conforms to the 04C-1 (ISO\/DIN) standard with a pitch of 6.35 mm (1\/4 in). Each link assembly consists of inner plates, outer plates, rollers, bushings, and pins. Available in carbon steel and 304 stainless steel variants, with roller diameters typically in the 3.3–4.0 mm range and inner width typically 3.18 mm (0.125 in). Cut lengths range from 0.5 m to 5 m (approx. 1.6 ft to 16.4 ft), with a separate connecting link available for easy joining.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include small conveyor systems requiring a compact 1\/4-inch pitch roller chain, DIY automation rigs and CNC axis drives needing a lightweight 04C-1 drive chain, and food-adjacent or corrosion-prone environments where a 304 stainless steel roller chain replacement is required.\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 all standard 04C-1 \/ 25H sprockets with 6.35 mm pitch.
