Manufactured from low carbon steel with a black oxide finish, this button provides a durable seating surface for precision workpiece positioning. The ground press fit design allows for secure installation into a bored hole without additional fasteners. At 3\/4 inch overall length with a 3\/8 inch head height and 3\/8 inch outside diameter, it suits compact tooling layouts. The pin diameter of 0.1885 inches enables a controlled press fit into standard receiving bores.\u003c\/p\u003e\n\u003cp\u003eThis rest button is used in machine shop and manufacturing environments where repeatable workpiece location is critical. Typical applications include drill jigs, milling fixtures, welding positioners, and assembly fixtures. The black oxide coating provides mild corrosion resistance during storage and use in shop environments. Machinists, tool and die makers, and fixture builders install this type of component as part of a precision locating system alongside other rest buttons, locating pins, and clamps.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGround press fit seating surface for accurate workpiece location\u003c\/li\u003e\n  \u003cli\u003eLow carbon steel construction for reliable structural integrity\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e0.1885 inch pin diameter for controlled press fit installation\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch head height and 3\/8 inch outside diameter for compact footprint\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch overall length suits standard jig and fixture plate thicknesses\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use component for press fit rest button applications in standard machine shop fixture and jig assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePress fit rest buttons are installed by tool and die makers or machinists using an arbor press or similar controlled-force equipment. The receiving bore should be sized to match the pin diameter within specified tolerance before installation to ensure proper fit and prevent damage to the button or plate. Always verify the bore is clean and free of burrs prior to pressing the button in place. Do not strike the button directly with a hammer, as this can damage the ground seating surface.\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\u003eOverall Length\u003c\/strong\u003e: 3\/4 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: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Diameter\u003c\/strong\u003e: 0.1885 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePress Fit Type\u003c\/strong\u003e: Ground\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: 0.02 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: 646405-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51716948164914,"sku":"646405-G","price":17.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/55a71237c941bb413a24da845dd78c77.jpg?v=1788533839","url":"https:\/\/voomisupply.com\/products\/gibraltar-646405-g-press-fit-rest-button-3-4-in-oal","provider":"Voomi Supply","version":"1.0","type":"link"}
