Constructed from low carbon steel with a black oxide coating, this rest button provides a hardened, wear-resistant contact point for locating and supporting workpieces on jigs, fixtures, and tooling plates. Key dimensions include a 31\/32-inch overall length, a 1\/2-inch head height, a 1\/2-inch outside diameter, and a 0.251-inch pin diameter. Installation is achieved via press fit, requiring no additional fasteners. Licensed machinists and toolmakers are the typical installers.\u003c\/p\u003e\u003cp\u003eThis rest button is suited for use in precision manufacturing, tooling, and fixturing setups where consistent and repeatable workpiece support is required. The ground finish ensures tight dimensional tolerances, making it appropriate for close-tolerance fixture plates in both job shop and production environments. The black oxide surface finish provides mild corrosion resistance while maintaining dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGround press fit design for accurate, repeatable installation in fixture plates\u003c\/li\u003e\n\u003cli\u003eLow carbon steel construction for durability in industrial workholding applications\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003cli\u003e0.251-inch pin diameter for consistent press fit retention\u003c\/li\u003e\n\u003cli\u003eCompact 1\/2-inch head height suitable for low-profile fixturing setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use component for standard press fit rest button applications in precision jigs, fixtures, and tooling plates where a 0.251-inch pin diameter press fit rest button is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit rest buttons are installed by machinists and toolmakers using a shop press or arbor press to seat the pin into a precisely reamed bore. Ensure the mating bore is reamed to the correct tolerance before pressing the button into place. Do not hammer the button directly, as this may damage the ground surface or alter dimensional accuracy. Verify fixture plate material and bore depth are compatible with this button before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 31\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Diameter\u003c\/strong\u003e: 0.251 inches\u003c\/li\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\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: 0.03 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: 646425-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51712537755954,"sku":"646425-G","price":17.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b5075ba0aa5f0f85a1242f92e8055b8a.jpg?v=1788486542","url":"https:\/\/voomisupply.com\/products\/gibraltar-646425-g-press-fit-rest-button-low-carbon-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
