It consists of a matched male and female washer pair that compensates for angular misalignment between a bolt and its mating surface. The female washer measures 9\/16 inches inside diameter with a 1-1\/8 inch outside diameter. The male washer measures 17\/32 inches inside diameter with a matching 1-1\/8 inch outside diameter. Both components are manufactured from 12L14 grade case hardened steel with a black oxide finish, providing corrosion resistance and a hardened wear surface. Total assembly thickness is 5\/16 inches with a 1-1\/2 inch spherical radius. Machinists, millwrights, and maintenance mechanics install these assemblies in structural bolted connections where surface parallelism cannot be guaranteed.\u003c\/p\u003e\n\u003cp\u003eThis spherical washer assembly is suited for industrial machinery, structural steel connections, and mechanical assemblies where bolt load must be evenly distributed across non-parallel surfaces. The self-aligning geometry reduces bending stress on the bolt shank, extending fastener service life in high-load or vibrating applications. It is commonly used in manufacturing facilities, heavy equipment maintenance, and general industrial construction where precise bolt alignment is difficult to achieve through surface preparation alone.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMatches 1\/2 inch bolt diameter for direct OEM-style fitment\u003c\/li\u003e\n  \u003cli\u003eSpherical geometry compensates for angular surface misalignment\u003c\/li\u003e\n  \u003cli\u003e12L14 grade case hardened steel construction for strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces surface galling\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch spherical radius distributes load evenly under off-angle bolt seating\u003c\/li\u003e\n  \u003cli\u003eSold as a complete male and female washer set, ready to install\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation spherical washer assembly for use with standard 1\/2 inch bolts in industrial and structural bolted connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance mechanics using standard hand and torque tools. The female washer seats against the fixed surface and the male washer seats against the bolt head or nut bearing face. Ensure the mating surfaces are clean and free of debris before assembly.
