Each package contains two screws designed to restore proper handwheel function on worn or damaged manifolds. Handwheel screws secure the valve handle assembly to the manifold body, allowing technicians to open and close refrigerant ports with consistent torque feel and positive shutoff. This hardware is a direct OEM-style replacement intended for HVAC and refrigeration technicians who service manifold gauge sets in the field or shop.\u003c\/p\u003e\u003cp\u003eThis screw set is suited for use during routine manifold maintenance or when a handwheel becomes loose, stripped, or non-functional. Keeping spare hardware on hand reduces downtime during refrigerant recovery, evacuation, and charging operations. The two-piece pack provides enough hardware to service both the high-side and low-side handwheels in a single job.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReplacement handwheel screws restore proper valve handle function on JB manifold gauge sets\u003c\/li\u003e\n\u003cli\u003ePack of 2 screws covers both high-side and low-side handwheel replacement in one purchase\u003c\/li\u003e\n\u003cli\u003eOEM-style fit eliminates the need to source generic hardware that may not seat correctly\u003c\/li\u003e\n\u003cli\u003eCompact consumable hardware suitable for field tool kits and shop inventory\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with all JB manifold gauge set models per manufacturer specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified HVAC or refrigeration technician. Before replacing handwheel screws, recover any system refrigerant and depressurize the manifold per standard safe-handling procedures. Use the appropriate hand tools and do not overtighten, as overtorquing small manifold hardware can strip threads or crack the handwheel body. Follow applicable EPA Section 608 guidelines when working with refrigerant-side components.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2 screws\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Manifold gauge set handwheel replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: JB INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: mr-503\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JB INDUSTRIES","offers":[{"title":"Default Title","offer_id":51467867881778,"sku":"MR-503","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945379.jpg?v=1783912789","url":"https:\/\/voomisupply.com\/products\/jb-industries-mr-503-handwheel-screws-pack-of-2","provider":"Voomi Supply","version":"1.0","type":"link"}
