Constructed from low carbon steel with a black oxide coating, this button provides a hardened, ground seating surface for workpiece support and location. The ground press fit design ensures accurate, repeatable positioning when pressed into a mating bore. It measures 27\/32 inches in overall length with a 5\/8 inch outside diameter, a 3\/8 inch head height, and a pin diameter of 0.3760 inches. Machinists, toolmakers, and fixture builders install this type of component during machine setup and workholding fabrication.\u003c\/p\u003e\u003cp\u003ePress fit rest buttons are used in jigs, fixtures, and workholding assemblies where a stable, precise contact point is required to support or locate a workpiece. The ground surface finish ensures minimal runout and consistent contact. This button is suited for use in both production machining environments and toolroom applications where dimensional repeatability is critical. It installs directly into a pre-bored hole in a fixture plate or body.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGround press fit design for accurate, repeatable seating in fixture bores\u003c\/li\u003e\n\u003cli\u003eLow carbon steel construction for toughness in workholding applications\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating for corrosion resistance and reduced light reflection\u003c\/li\u003e\n\u003cli\u003e0.3760 inch pin diameter for precise bore fit\u003c\/li\u003e\n\u003cli\u003eCompact head profile at 3\/8 inch head height for low-clearance fixture designs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard press fit rest button for use in machinist jigs, fixtures, and workholding plates requiring a ground locating or support surface.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by toolmakers or machinists using a press or arbor press to drive the pin into a precision-bored hole. Ensure the receiving bore is machined to the appropriate tolerance for a press fit before installation. Pressing the button in by hand or hammer is not recommended, as it may damage the ground surface or misalign the button. Follow standard workholding and fixture design practices when specifying bore depth and fit class.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 27\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Diameter\u003c\/strong\u003e: 0.3760 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 Coating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePress Fit Type\u003c\/strong\u003e: Ground\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 646450-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51693392429362,"sku":"646450-G","price":18.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/31fe2842f90c481625668aaee6b154bd.jpg?v=1788311674","url":"https:\/\/voomisupply.com\/products\/gibraltar-646450-g-press-fit-rest-button-ground-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
