Engineers, maintenance technicians, and serious DIYers who work with 08B-1 pitch roller chains need a connecting link that installs quickly, holds securely, and resists the corrosive environments that destroy standard carbon steel hardware.\u003c\/p\u003e\n    \u003cp\u003eThis 40# 08B-1 stainless steel roller chain hollow pin connecting link is engineered for standard 08B-1 (ANSI #40) roller chains with a 12.70 mm (1\/2 inch) pitch. The hollow pin design allows the clip or cotter pin to seat firmly, ensuring the link stays locked under load. Constructed from stainless steel for corrosion resistance, the link is compatible with chains conforming to ISO 606 \/ DIN 8187 08B-1 specifications.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases
