Deutz BFM1013 TCD2013 Engine parts Big end bolt 0420 0468

As a China-based factory-direct exporter of precision engine fasteners, we supply the Deutz BFM1013 big end bolt (part 0420 0468), a critical connecting rod fastener engineered for 1013-series diesel engines used in stationary generator sets, heavy-duty road trucks, and auxiliary marine propulsion where sustained high RPM and cyclic torque prevail. Manufactured from SCM435 alloy steel and cold-forged to property class 12.9, our bolt delivers minimum tensile strength of 1,220 MPa with consistent clamp load retention under thermal cycling and vibrational stress. Each batch undergoes dimensional gauging, hardness testing (HRC 39–44), and metallographic inspection to verify grain flow integrity, with optional surface coating (Dacromet/Zinc-flake) for corrosion resistance in humid or salt-spray environments. We supply both single-piece overhaul kits and bulk packaging for engine rebuild shops, backed by full torque spec documentation (recommended 120 Nm + 90° angle-tightening) and traceable lot numbers. With stock-holding capacity and flexible shipping via air or sea from major China ports, we ensure rapid response for emergency downtime repairs as well as scheduled maintenance programs, delivering OEM-level safety margins at competitive export pricing.
