Built with an aluminum body measuring 1.5 inches wide by 1 inch long, this spring stop delivers a 3\/16 inch stroke length with a progressive force profile: 2 pounds initial end force, 14 pounds middle end force, and 25.9 pounds final end force. The tang profile and square stop head allow repeatable part location and controlled detent action. Machinists, toolmakers, and assembly technicians install this type of component in jigs, fixtures, and automated assembly equipment where consistent part positioning is required.\u003c\/p\u003e\u003cp\u003eThe SS90A is suited for light-duty to medium-duty fixture and tooling applications. The mounting slot configuration accepts standard fastener hardware, with slot dimensions of 3\/16 inch length by 0.203 inch width. The 1-1\/8 inch distance between mounting hole centers and 0.938 inch distance between mounting hole and edge allow straightforward integration into existing fixture plates or tooling blocks. The stop head measures 0.875 inch wide by 0.875 inch high with a 0.25 inch thickness, providing a defined contact surface for repeatable workpiece registration.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eProgressive spring force: 2 lb initial, 14 lb middle, and 25.9 lb final end force for controlled detent engagement\u003c\/li\u003e\n\u003cli\u003eTang profile provides positive rotational and lateral location of stop head\u003c\/li\u003e\n\u003cli\u003eAluminum body construction for lightweight installation in fixture and tooling applications\u003c\/li\u003e\n\u003cli\u003e3\/16 inch stroke length suitable for short-travel positioning tasks\u003c\/li\u003e\n\u003cli\u003eMounting slots sized at 0.203 inch width for standard fastener compatibility\u003c\/li\u003e\n\u003cli\u003eCompact 1.5 inch body width keeps fixture footprint minimal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for fixture plates, tooling jigs, and mechanical assemblies requiring a tang square spring locating stop with a 1.5 inch body width and 1 inch body length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by toolmakers or mechanical assemblers using standard hand tools and fasteners appropriate to the mounting slot dimensions. Ensure the mating fixture surface is clean and flat before securing the stop to prevent misalignment under load. Follow applicable machine safety lockout and tagout procedures before installing or removing spring stops in powered equipment. Do not exceed the rated final end force when compressing the stop, as overloading can deform the spring mechanism.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Width\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStroke Length\u003c\/strong\u003e: 0.188 inches (3\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStop Head Width\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStop Head Height\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStop Head Thickness\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTang Profile\u003c\/strong\u003e: Tang\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTang Width\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMiddle End Force\u003c\/strong\u003e: 14 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 25.9 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistance Between Mount Hole Centers\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistance Between Mount Hole and Edge\u003c\/strong\u003e: 0.938 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Slot Length\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Slot Width\u003c\/strong\u003e: 0.203 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VLIER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SS90A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51994731544882,"sku":"SS90A","price":19.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e608354792f86987213ba4a33561b05.jpg?v=1789992126","url":"https:\/\/voomisupply.com\/products\/vlier-ss90a-tang-square-spring-locating-stop","provider":"Voomi Supply","version":"1.0","type":"link"}
