The rolling ball end allows the fastener to apply even clamping force against angled or irregular surfaces without marring the workpiece. Manufactured from 18-8 stainless steel throughout, including the ball, this screw resists corrosion in wet or washdown environments. The 3\/8-16 UNC thread and 0.75-inch overall length make it a compact, direct-drive fastener suitable for jig plates, fixture blocks, and machine tool setups installed by machinists, toolmakers, and maintenance technicians.\u003c\/p\u003e\u003cp\u003eThis clamping screw is used in precision machining fixtures, tooling plates, and workholding assemblies where a positive, non-marring contact point is required. The headless design allows the screw to sit flush or below the surface of a tapped hole, keeping the fixture profile low. Typical installations include drill jigs, milling fixtures, and modular fixturing systems in production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRolling ball end provides self-aligning, non-marring contact on workpiece surfaces\u003c\/li\u003e\n\u003cli\u003eHeadless design enables flush or sub-flush installation in tapped holes\u003c\/li\u003e\n\u003cli\u003e18-8 stainless steel screw body and ball for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e3\/8-16 UNC thread for broad compatibility with standard tapped fixturing components\u003c\/li\u003e\n\u003cli\u003e0.275-inch ball diameter delivers focused clamping force at contact point\u003c\/li\u003e\n\u003cli\u003e0.032-pound weight keeps fixture assembly mass low\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any standard 3\/8-16 UNC tapped hole in fixturing plates, jig bodies, or workholding assemblies requiring a rolling ball end clamping screw.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a hex key or spanner sized to the headless drive recess; confirm drive type before installation. Ensure the mating tapped hole is clean and free of chips before threading in the screw. Do not overtighten against hardened surfaces, as the rolling ball is designed for clamping load, not impact. In stainless-to-stainless thread engagements, apply an anti-galling compound to prevent thread seizure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 UNC\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: Stainless Steel, Grade 18-8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Material\u003c\/strong\u003e: Stainless Steel\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: 9534SS-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51692497568050,"sku":"9534SS-G","price":23.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c08cbee171809c1bfdfd4c680e6bd18.jpg?v=1788298447","url":"https:\/\/voomisupply.com\/products\/gibraltar-9534ss-g-rolling-ball-clamping-screw-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
