The screw features a 1\/2-13 UNC thread and measures 1 inch overall length (OAL). The rolling ball end, measuring 0.334 inches in diameter and made from stainless steel, allows the clamping point to self-align against irregular or angled workpiece surfaces without marring. The body is steel with a black oxide finish for corrosion resistance. Drive is via a 1\/4-inch hex key. This fastener is sized for applications where a flush or recessed drive head is required and a standard socket or cap screw head would interfere with the assembly.\u003c\/p\u003e\u003cp\u003eThe 9536-G is used in machine shop fixturing, modular workholding systems, die sets, and precision tooling plates where controlled clamping force and low-profile installation are required. The rolling ball tip accommodates slight angular misalignment between the screw axis and the clamping surface, making it suitable for clamping against angled faces or curved workpieces. Typical installers include machinists, tool and die makers, and mechanical assembly technicians working with production fixtures.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRolling stainless steel ball end self-aligns to angled or irregular clamping surfaces\u003c\/li\u003e\n\u003cli\u003eHeadless design sits flush or below surface level for low-profile fixturing\u003c\/li\u003e\n\u003cli\u003e1\/4-inch hex key drive for controlled torque in tight clearance environments\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides moderate corrosion resistance in shop environments\u003c\/li\u003e\n\u003cli\u003e1\/2-13 UNC thread for broad compatibility with standard tapped fixture components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit clamping screw for standard 1\/2-13 UNC tapped holes in modular fixturing plates, tooling blocks, and workholding components requiring a rolling ball end style.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 1\/4-inch hex key; ensure the tapped hole is clean and free of chips before threading the screw in. De-energize or lock out any powered equipment and secure the workpiece before applying clamping force. Do not exceed the torque rating of the mating tapped component, particularly in aluminum or soft tooling plate. Inspect the rolling ball for free rotation and seating before use to confirm proper self-alignment function.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.334 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Style\u003c\/strong\u003e: Rolling Ball\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Headless\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.094 pounds\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: 9536-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51711538594098,"sku":"9536-G","price":20.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c08cbee171809c1bfdfd4c680e6bd18_e16bc41f-ab53-4b74-be05-b6d57bd37a8f.jpg?v=1788476793","url":"https:\/\/voomisupply.com\/products\/gibraltar-9536-g-rolling-ball-clamping-screw-1-2-13","provider":"Voomi Supply","version":"1.0","type":"link"}
