With a 27\/32 inch inside diameter, a 1-3\/8 inch body outside diameter, and a 1 inch length under the head, this bushing installs directly into a drill jig plate without the need for a liner bushing. The head sits flush on top of the jig plate to prevent the bushing from being pushed through during operation. Inside diameter tolerance is held to +0.0002 to +0.0006 inches, ensuring consistent, repeatable hole location accuracy. Machinists, toolmakers, and production drilling personnel are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe H8816NR is suited for use in drill jigs across general metalworking, fabrication, and light manufacturing environments. It is intended for permanent or long-run installations where the jig setup does not require frequent bushing changes. The headed design prevents pull-through on through-plate jig applications. The steel construction withstands the abrasion and heat generated during repeated drilling cycles. This bushing is not counterbored and is not classified as a renewable bushing, making it appropriate for fixed jig tooling rather than interchangeable tooling systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType H press fit installation — no liner bushing required\u003c\/li\u003e\n  \u003cli\u003e27\/32 inch inside diameter with a tight tolerance of +0.0002 to +0.0006 inches for accurate hole guidance\u003c\/li\u003e\n  \u003cli\u003e1-3\/8 inch body outside diameter and 1 inch length under head for secure seating in jig plates\u003c\/li\u003e\n  \u003cli\u003eHead outside diameter of 1-39\/64 inches and head height of 3\/8 inch prevent pull-through during drilling\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability under repeated drilling cycles\u003c\/li\u003e\n  \u003cli\u003eNon-renewable, non-counterbored design suited for permanent jig tooling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style fixed drill jig bushing conforming to Type H headed press fit bushing standards, suitable for drill jig plates requiring a permanent, non-renewable bushing installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolmakers or machining personnel using a press or arbor press to drive the bushing into the jig plate bore. The jig plate bore must be machined to the appropriate interference fit tolerance before installation. Once pressed in, the bushing is not intended for removal or reuse. Ensure the jig plate is clean and free of burrs before pressing to avoid damage to the bushing or plate.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 27\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0002 to +0.0006 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 1-39\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Configuration\u003c\/strong\u003e: Headed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable Bushing\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171603\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: BONEHAM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H8816NR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51727225422130,"sku":"H8816NR","price":31.71,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/15cc7145ff715231e9092eb0cfc5e6d1.jpg?v=1788674977","url":"https:\/\/voomisupply.com\/products\/boneham-h8816nr-press-fit-headed-drill-bushing-type-h","provider":"Voomi Supply","version":"1.0","type":"link"}
