Manufactured from steel throughout, this set-screw-style fastener uses an M4 thread and accepts a 2.00 mm hex key for installation and adjustment. The ball end measures 2.50 mm in diameter and provides a self-aligning contact point against the workpiece, reducing marring while maintaining clamping force. Rated for a maximum load capacity of 786 pounds, this screw delivers reliable holding force in compact fixture assemblies where a low-profile, headless design is required.\u003c\/p\u003e\n\u003cp\u003eThis clamping screw is suited for use in modular fixturing systems, tooling plates, vise jaws, and precision machine tool accessories found in manufacturing and metalworking environments. The flat face ball end style is commonly specified where point contact with the workpiece must be maintained at slight angular offsets without damaging the clamped surface. Machinists, toolmakers, and fixture builders will encounter this style in both production and prototype fixturing setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHeadless design sits flush with or below the fixture surface to avoid interference\u003c\/li\u003e\n  \u003cli\u003ePlain flat face ball end provides self-aligning contact and reduces workpiece marring\u003c\/li\u003e\n  \u003cli\u003eM4 thread with 2.00 mm hex key drive for easy installation in tight spaces\u003c\/li\u003e\n  \u003cli\u003e786-pound maximum load capacity for secure clamping in demanding fixturing applications\u003c\/li\u003e\n  \u003cli\u003eAll-steel construction, both screw body and ball, for durability and wear resistance\u003c\/li\u003e\n  \u003cli\u003e15.60 mm overall length suits compact fixture and tooling plate applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-specification component for M4-threaded workholding fixtures, tooling plates, and modular fixturing systems requiring a headless ball end clamping screw.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 2.00 mm hex key; use a calibrated torque wrench or T-handle to avoid overdriving the M4 thread in aluminum or softer fixture bodies. Ensure the mating threaded hole is clean and free of chips before installation. Do not exceed the rated 786-pound load capacity. Machinists and toolmakers performing fixture assembly should verify thread engagement depth meets the fixture manufacturer's specification before applying clamping load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Load Capacity\u003c\/strong\u003e: 786 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 15.60 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 2.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 2.00 mm\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\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: 0.002 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: 22720.0546\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51693434536242,"sku":"22720.0546","price":23.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9abc267fe0896b5213b2fdc8571765e8_db6cf104-0ec9-454f-977b-9f6a0467152d.jpg?v=1788312341","url":"https:\/\/voomisupply.com\/products\/gibraltar-22720-0546-headless-ball-end-clamping-screw-m4","provider":"Voomi Supply","version":"1.0","type":"link"}
