It features a 5\/16-18 UNC thread with a 0.750 inch overall length and a 0.147 inch diameter stainless steel ball at its tip. The headless design allows flush or below-surface installation, while the flat face ball end provides a smooth, low-friction contact point against workpiece surfaces. A 5\/32 inch hex key drives the screw for precise, controlled clamping force. The steel body carries a black oxide finish for corrosion resistance in shop environments. Typically installed by machinists, toolmakers, and fixture builders.\u003c\/p\u003e\n\u003cp\u003eThis clamping screw is suited for use in jigs, fixtures, clamps, and toolholding components where a compact, headless fastener is required to apply localized clamping pressure. The plain flat face ball end reduces marring on workpiece contact surfaces. Its UNC thread form is compatible with standard tapped holes in fixture plates, vise jaws, and modular tooling systems. The short 0.750 inch overall length makes it appropriate for low-profile fixture blocks and tight-clearance assemblies common in both manual and CNC machine shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHeadless design allows flush or recessed installation in fixture components\u003c\/li\u003e\n  \u003cli\u003ePlain flat face stainless steel ball end minimizes marring on clamped surfaces\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread for compatibility with standard tapped fixture plates\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance in shop environments\u003c\/li\u003e\n  \u003cli\u003e5\/32 inch hex key drive for controlled torque application\u003c\/li\u003e\n  \u003cli\u003eCompact 0.750 inch overall length suits low-profile and tight-clearance fixtures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stock clamping screw for jigs, fixtures, clamps, and modular tooling components using 5\/16-18 UNC tapped holes.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolmakers using a 5\/32 inch hex key. Ensure the receiving threaded hole is clean and free of debris before installation. Do not overtighten, as excess force can damage the ball end or deform softer fixture materials. De-energize or lock out any associated machine before adjusting or replacing clamping screws in active fixtures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.147 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Headless\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Style\u003c\/strong\u003e: Plain Flat Face\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 5\/32 inches\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: 0.01875 pounds\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: 9512-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51704987615538,"sku":"9512-G","price":20.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b1506aa263203f2b3a5ecb16d66c03bf.jpg?v=1788426189","url":"https:\/\/voomisupply.com\/products\/gibraltar-9512-g-headless-clamping-screw-5-16-18-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
