Manufactured from low carbon steel with a black oxide coating, this ground button provides a controlled interference fit when installed into a mating bore. It measures 1.375 inches in overall length with a 1 inch outside diameter and a 7\/16 inch head height. The ground finish ensures tight dimensional tolerances, making it suitable for applications where consistent contact surfaces are required. Machinists, tool and die makers, and fixture builders typically install this component during fixture fabrication or maintenance.\u003c\/p\u003e\n\u003cp\u003eThis rest button is used in precision workholding fixtures, drill jigs, and machining plates across metalworking and manufacturing environments. The press fit design allows secure installation without fasteners, and the ground seating surface provides a stable, flat reference point for part location. The black oxide finish offers mild corrosion resistance and reduces light reflection in inspection environments. It is sold individually and is appropriate for both new fixture builds and replacement applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation with ground finish for tight dimensional control\u003c\/li\u003e\n  \u003cli\u003eLow carbon steel construction with black oxide coating for mild corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e1 inch outside diameter with 0.626 inch pin diameter for precise bore engagement\u003c\/li\u003e\n  \u003cli\u003e7\/16 inch head height provides a defined seating surface for workpiece contact\u003c\/li\u003e\n  \u003cli\u003eGround seating face supports repeatable part location in fixtures and jigs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation press fit rest button for precision machining fixtures, drill jigs, and workholding plates requiring a 1 inch outside diameter ground rest button with a 0.626 inch pin diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by tool and die makers or machinist trades using an arbor press or hydraulic press to drive the button into a prepared bore. The mating bore should be finish-reamed to the specified interference fit tolerance before installation. Do not hammer the button in freehand, as this can damage the ground seating face or distort the bore. Follow applicable shop standards and fixture design specifications for hole preparation and press force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eButton Type\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePress Fit Type\u003c\/strong\u003e: Ground\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.4375 inches (7\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Diameter\u003c\/strong\u003e: 0.626 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Low Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 646482-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":67909770805554,"sku":"646482-G","price":30.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/58e6a6e507c12a415ffb8642c9449840.jpg?v=1791191943","url":"https:\/\/voomisupply.com\/products\/gibraltar-646482-g-press-fit-rest-button-1-inch-od","provider":"Voomi Supply","version":"1.0","type":"link"}
