Manufactured from steel with a bright uncoated finish, it provides mechanical resistance to fastener loosening caused by vibration and dynamic loads. The washer features an inside diameter range of 0.318 to 0.338 inches and a maximum outside diameter of 0.46 inches, with a thickness of 0.093 inches. This style of lock washer is widely used in mechanical assembly, HVAC equipment mounting, electrical enclosures, and general industrial fastening applications. The box contains 100 washers.\u003c\/p\u003e\n\u003cp\u003eHigh collar split lock washers are suited for applications where standard-height lock washers may not provide adequate bite or bearing surface. The high collar design increases contact area against the fastener head or mating surface, making it a common choice in equipment assembly, panel fabrication, and structural fastening in both commercial and industrial settings. Licensed tradespeople and assembly technicians working on HVAC units, electrical panels, and mechanical equipment regularly specify this washer type when code or equipment standards call for vibration-resistant fastening.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh collar design increases bearing surface contact compared to standard split lock washers\u003c\/li\u003e\n  \u003cli\u003eInside diameter range of 0.318 to 0.338 inches fits 5\/16 inch fasteners\u003c\/li\u003e\n  \u003cli\u003eMaximum outside diameter of 0.46 inches for compact footprint in tight clearance applications\u003c\/li\u003e\n  \u003cli\u003eSteel construction with bright uncoated finish for general-purpose indoor mechanical use\u003c\/li\u003e\n  \u003cli\u003eThickness of 0.093 inches provides consistent spring tension under load\u003c\/li\u003e\n  \u003cli\u003eSold in a box of 100 for production, service, or shop stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 5\/16 inch screws and bolts in standard inch-measurement fastening applications.
