Manufactured from steel throughout — both the screw body and the rolling ball — this fastener provides reliable clamping force with a rated maximum load capacity of 3,272 pounds. The M8 thread size and 17.2mm overall length make it a compact yet high-capacity component suited for use in jigs, fixtures, vises, and tooling plates. Installation requires a 4mm hex key. The 5.5mm rolling ball end allows multi-angle contact with the clamped workpiece, distributing load without marring surfaces. Machinists, toolmakers, and fixture builders are the primary installers of this type of hardware.\u003c\/p\u003e\n\u003cp\u003eThis clamping screw is used in machine shop and manufacturing environments where secure, adjustable workholding is required. It is suited to both light production and precision toolroom work. The headless design keeps the fastener flush or recessed within the fixture body, which is critical in applications where clearance is limited or where protruding hardware would interfere with workpiece positioning or machine travel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHeadless design allows flush or recessed installation in fixture bodies\u003c\/li\u003e\n  \u003cli\u003eRolling ball end enables multi-angle contact and reduces surface marring on clamped parts\u003c\/li\u003e\n  \u003cli\u003eM8 thread size for compatibility with standard metric fixture and tooling plate tapped holes\u003c\/li\u003e\n  \u003cli\u003e3,272 pound maximum load capacity for demanding workholding applications\u003c\/li\u003e\n  \u003cli\u003e5.5mm ball diameter provides controlled contact area\u003c\/li\u003e\n  \u003cli\u003eSteel construction on both screw body and ball for durability in shop environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for metric M8 tapped workholding fixtures, jigs, tooling plates, and vise assemblies requiring a headless rolling ball end clamping screw.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolmakers using a 4mm hex key.
