When this component fails or becomes deformed, fasteners can back out during operation, leading to mechanical loosening, misalignment, or component damage that can sideline a machine mid-job.\u003c\/p\u003e\u003cp\u003ePart number 10637 is a 3\/8\" countersunk lockwasher designed specifically for Bartell Global walk-behind trowel assemblies. The countersunk profile seats flush against recessed fastener surfaces, maintaining a low-profile installation while delivering consistent locking force. During routine maintenance inspections or any disassembly involving countersunk fasteners, this washer should be replaced rather than reused, repeated torque cycles compress and fatigue the locking geometry, reducing its effectiveness over time. Always inspect mating surfaces for wear or scoring when replacing hardware on trowel assemblies, and install new lockwashers any time a fastened joint is broken.\u003c\/p\u003e\u003cp\u003eCompatible with the following Bartell Global walk-behind trowel models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eB436\u003c\/li\u003e\n\u003cli\u003eB446\u003c\/li\u003e\n\u003cli\u003eB446 MEGA-T\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eGenuine Bartell Global OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Bartell","offers":[{"title":"Default Title","offer_id":43412750565424,"sku":"10637","price":47.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/10637.jpg?v=1784313025","url":"https:\/\/cce-industries.com\/products\/bartell-10637-lockwasher-3-8-countersunk-oem-replacement-part","provider":"CCE Industries","version":"1.0","type":"link"}
