Threaded 3\/8-16 UNC, it features a 0.275-inch stainless steel rolling ball tip that allows smooth, self-centering contact against a workpiece without marring the surface. The screw body is steel with a black oxide finish for corrosion resistance. At 0.75 inches overall length, this compact fastener is suited for tight-clearance setups where a headed screw would interfere. Machinists, toolmakers, and fixture builders use this style of clamping screw in jigs, vises, and precision workholding assemblies.\u003c\/p\u003e\u003cp\u003eThis clamping screw is used in machine shop environments for fixture plates, jig bodies, and modular workholding systems. Its rolling ball tip reduces friction and point loading on the clamped surface, making it appropriate for holding finished or semi-finished parts during secondary operations. The headless profile allows installation flush with or below a tapped surface, keeping the fixture compact and snag-free. Suitable for both production and one-off toolroom applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHeadless design for flush or sub-flush installation in tapped bores\u003c\/li\u003e\n\u003cli\u003eRolling stainless steel ball tip provides self-centering, low-friction contact\u003c\/li\u003e\n\u003cli\u003e3\/8-16 UNC thread for wide compatibility with standard fixture hardware\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish on steel body for added corrosion resistance\u003c\/li\u003e\n\u003cli\u003eCompact 0.75-inch overall length for tight-clearance workholding setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or addition for 3\/8-16 UNC tapped workholding fixtures, jig plates, and modular fixturing systems requiring a headless rolling ball end clamping screw.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a hex key or Allen wrench sized for the headless drive recess; confirm the thread engagement depth is sufficient before applying clamping load. Ensure the mating tapped hole is clean and free of chips before threading in the screw. Do not overtighten, as the rolling ball tip is designed for controlled clamping pressure, not torque-intensive fastening. Deburr tapped holes prior to installation to protect the ball and thread surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.275 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: Rolling Ball\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: 0.032 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: 9534-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51695323775282,"sku":"9534-G","price":17.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/62a06297fd2af2b2ab9b26c57f632c73.jpg?v=1788333897","url":"https:\/\/voomisupply.com\/products\/gibraltar-9534-g-rolling-ball-clamping-screw-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
