Sized for a 1-inch thread, it features an outer diameter of 1.5354 inches and an inner diameter of 1.1063 inches. The zinc flake finish provides corrosion protection in demanding environments. Manufactured to Grade 2 material standards and conforming to ISO 9001 and ISO 14001 quality and environmental management certifications, this washer is a dependable choice for industrial, mechanical, and structural fastening applications. Each package contains 10 washers.\u003c\/p\u003e\n\u003cp\u003eWedge lock washers are used wherever bolt loosening due to vibration or dynamic loads is a concern. Common applications include machinery assembly, structural steel connections, automotive fixtures, and equipment mounting in industrial facilities. The interlocking wedge geometry creates a mechanical locking action as the fastener is tightened, resisting back-rotation under cyclic loading. Licensed mechanics, millwrights, and maintenance technicians regularly specify this style of washer in assemblies subject to continuous vibration or thermal cycling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWedge-profile geometry provides mechanical vibration resistance without adhesives or thread-locking compounds\u003c\/li\u003e\n  \u003cli\u003e1-inch thread size with 1.5354-inch OD and 1.1063-inch ID for precise fastener fit\u003c\/li\u003e\n  \u003cli\u003eSteel construction, Grade 2, for strength in general industrial use\u003c\/li\u003e\n  \u003cli\u003eZinc flake finish delivers corrosion protection in moderate-exposure environments\u003c\/li\u003e\n  \u003cli\u003eManufactured under ISO 9001 and ISO 14001 certified quality systems\u003c\/li\u003e\n  \u003cli\u003eSold in a 10-piece package to support standard fastener quantities\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation washer for 1-inch threaded fastener assemblies requiring a wedge lock style washer in steel with zinc-plated finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanics, millwrights, or maintenance technicians using standard hand or power tools appropriate for the fastener assembly.
