Manufactured from case-hardened C1215 steel, this pin delivers a hard exterior surface with a tough core, making it well suited for applications where wear resistance and shear strength matter. The pin measures 5\/16 inches in diameter with an overall length of 3\/4 inches (0.7500 decimal inches). Diameter tolerance is held to 0.0001 to 0.0003 inches, which is appropriate for close-fit and press-fit bore applications. One end is beveled for guided insertion; the opposite end is threaded to allow mechanical pull-out without damage to the bore. Machinists, maintenance technicians, and assembly mechanics are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis dowel pin is used wherever a removable, precision-locating fastener is needed in light mechanical, industrial, or trade equipment assemblies. The flat vent groove running the length of the pin allows air and lubricant to escape during insertion, preventing hydraulic lock in blind holes. This design is standard in tooling plates, jigs, fixtures, and mechanical assemblies found in HVAC equipment frames, pump housings, and similar trade hardware. The single-piece, individual-quantity packaging makes it a practical replacement or repair unit for field and shop use alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlat vent groove prevents hydraulic lock during insertion into blind holes\u003c\/li\u003e\n  \u003cli\u003eCase-hardened C1215 steel construction for wear resistance and core toughness\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of 0.0001 to 0.0003 inches supports close-fit and press-fit applications\u003c\/li\u003e\n  \u003cli\u003eOne beveled end for guided entry; one threaded end for mechanical extraction\u003c\/li\u003e\n  \u003cli\u003eCompact 5\/16 x 3\/4 inch size suits tight-clearance assembly locations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service pin for mechanical assemblies requiring a 5\/16-inch diameter flat vent pull out dowel in C1215 case-hardened steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or mechanical technicians using a pin press or dead-blow mallet. Ensure the receiving bore is clean, properly sized, and free of burrs before insertion. The threaded end is intended for use with a pull-out tool or slide hammer extractor — do not attempt extraction by driving from the threaded end. Follow applicable machinery safety lockout and tagout procedures before servicing any assembly containing this pin.\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: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3\/4 inches (0.7500 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\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\u003eEnd Type\u003c\/strong\u003e: One beveled, one threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: Z1250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51699442516274,"sku":"Z1250","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fea2145f53de41a955de59b0facd345c.jpg?v=1788375735","url":"https:\/\/voomisupply.com\/products\/gibraltar-z1250-flat-vent-pull-out-dowel-pin-5-16x3-4-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
