It measures 0.5 inches in diameter and 1.75 inches in overall length, with a diameter tolerance held between 0.0001 and 0.0003 inches for tight, repeatable fits. One end is beveled for guided entry and the other end is threaded for pull-out extraction. This pin is suited for fixturing, alignment, and positioning applications where the pin must be removed without full disassembly. Machinists, toolmakers, and maintenance technicians install this type of pin in production and repair environments.\u003c\/p\u003e\n\u003cp\u003eThe Z1256 is used in jigs, fixtures, and assemblies where a precision-ground dowel must be extracted by threaded puller rather than pressed or knocked out. The flat vent feature relieves hydraulic pressure during insertion into blind holes, preventing hydraulic lock. Sold individually, this pin fits applications calling for a 0.5-inch nominal diameter flat vent pull out style dowel in steel construction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlat vent design relieves hydraulic pressure in blind-hole installations\u003c\/li\u003e\n  \u003cli\u003eThreaded end allows puller-based extraction without damage to the bore\u003c\/li\u003e\n  \u003cli\u003eBeveled end guides entry and reduces installation effort\u003c\/li\u003e\n  \u003cli\u003eCase-hardened C1215 steel for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of 0.0001 to 0.0003 inches for precision alignment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 0.5-inch diameter flat vent pull out dowel pin for use in jigs, fixtures, and mechanical assemblies requiring precision alignment and tool-assisted extraction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or maintenance technicians using a press or mallet for seating and a threaded puller for removal. Ensure the receiving bore is clean and within tolerance before insertion. The flat vent channel must be oriented to allow trapped air and fluid to escape during press-in. Never force the pin into an undersized or damaged bore, as this can compromise the mating surface and the pin's extractability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Flat Vent Pull Out\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: 0.0001 to 0.0003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: One beveled, one threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Case-Hardened Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C1215\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: Z1256\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51710181343538,"sku":"Z1256","price":17.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/46f08cca99fb6c56a313c822e4aabb61.jpg?v=1788463976","url":"https:\/\/voomisupply.com\/products\/gibraltar-z1256-flat-vent-pull-out-dowel-pin-c1215","provider":"Voomi Supply","version":"1.0","type":"link"}
