Makers, hobbyists, and repair technicians who need a dependable replacement or upgrade for compact drive systems will find the 03C simplex roller chain a precise, drop-in solution.\u003c\/p\u003e\n    \u003cp\u003eThis listing covers a 03C simplex roller chain in a 1-metre (approx. 39.4 in) cut length, featuring a 4.7625 mm (3\/16 in) pitch — the standard spacing for 03C-series sprockets. The chain is available in three finish options: Silver (natural steel), Black (oxidized or coated), and Gold (zinc or brass-tone plated), each sold individually (1PCS), in pairs (2PCS), or in packs of five (5PCS).\u003c\/p\u003e\n    \u003cp\u003eTypical applications include go-kart and mini-bike final drives, small conveyor indexing systems, RC vehicle scale drivetrains, clock and timing mechanism replacements, and compact power-transmission assemblies where a 03C-pitch sprocket is already installed.\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 03C simplex sprockets with 4.7625 mm (3\/16 in) pitch.

Gold suggests a zinc-plated or brass-tone coating that adds a layer of surface protection and a distinctive appearance. For outdoor or high-humidity environments, consider pairing any finish with a suitable chain lubricant.\u003c\/p\u003e\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eCan I join two 1-metre lengths to make a longer chain?\u003c\/summary\u003e\n      \u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eYes. Standard 03C connecting links (also called master links) allow you to join multiple strands end-to-end. Ensure you use a connecting link rated for 03C pitch.
