Constructed from steel with a steel rolling ball end, this screw provides consistent, low-friction clamping force against a workpiece or fixture surface. The rolling ball contact point allows slight angular misalignment while maintaining firm, uniform pressure. At 16mm overall length (OAL) and rated to a maximum load capacity of 1,011 pounds, it suits moderate-duty clamping tasks in tooling plates, jigs, and machine fixture assemblies. Machinists, toolmakers, and fixture builders are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis clamping screw is typically used in machine shop and manufacturing environments where positive, adjustable clamping pressure is needed against a workpiece, stop block, or sliding fixture element. The headless design allows the screw to sit flush or recessed within a tapped hole, keeping the fixture profile low and unobstructed. Its compact 16mm OAL makes it well-suited for tight-clearance tooling plates, modular fixturing systems, and precision jig assemblies where a standard hex socket drive is used for adjustment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHeadless design for low-profile, flush or recessed installation in tapped bores\u003c\/li\u003e\n  \u003cli\u003eRolling ball end allows slight angular misalignment while maintaining clamping contact\u003c\/li\u003e\n  \u003cli\u003eSteel screw and steel ball construction for durability in machine shop environments\u003c\/li\u003e\n  \u003cli\u003e1,011 lb maximum load capacity suits moderate-duty fixturing tasks\u003c\/li\u003e\n  \u003cli\u003e16mm overall length fits compact tooling plates and jig assemblies\u003c\/li\u003e\n  \u003cli\u003e3mm ball diameter provides a defined, consistent contact point on clamped surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install component for standard tapped fixture holes accepting headless clamping screws of equivalent thread size and overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolmakers using a hex key or Allen wrench sized to the screw drive. Ensure the mating tapped hole is clean and free of debris before threading the screw in. Do not exceed the rated maximum load capacity of 1,011 pounds to avoid deformation of the ball end or thread damage. Back the screw out fully before removing or repositioning any clamped workpiece to prevent surface marring.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 16mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 3mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Load Capacity\u003c\/strong\u003e: 1,011 lb\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.004 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 22720.0055\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51698871861554,"sku":"22720.0055","price":16.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c7f67be7ebd9eb024219830f1e18ec1b.jpg?v=1788369184","url":"https:\/\/voomisupply.com\/products\/gibraltar-22720-0055-headless-rolling-ball-clamping-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
