The screw features a 20 mm shoulder diameter and a 100 mm shoulder length, providing a reliable pivot or spacer point in mechanical assemblies. Constructed from alloy steel at material grade 12.9, it delivers high tensile and shear strength suitable for demanding industrial use. The hex socket drive allows for high-torque installation in confined spaces. The head diameter ranges from 29.67 to 30 mm with a head height of 13.73 to 14 mm. The finish is uncoated. Maintenance technicians, machine builders, and industrial assemblers are the primary installers of this fastener type.\u003c\/p\u003e\u003cp\u003eThis shoulder screw is used in machine design, jig and fixture building, and mechanical linkage assemblies where a precision-ground cylindrical shoulder acts as a bearing surface, pivot point, or guide pin. It is appropriate for both light industrial and heavy-duty mechanical applications. The M16x2 thread size and 12.9 material grade make it well suited for high-load assemblies where standard fasteners would not provide adequate strength or dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e20 mm shoulder diameter provides a precision bearing and pivot surface\u003c\/li\u003e\n\u003cli\u003e100 mm shoulder length accommodates deep assemblies and linkage stacks\u003c\/li\u003e\n\u003cli\u003eAlloy steel at grade 12.9 for high tensile and proof load capacity\u003c\/li\u003e\n\u003cli\u003eHex socket drive enables high-torque installation in tight clearances\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use with added lubricants or coatings as needed\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3.3.M, BS 4168, ISO 7370, and ISO 7379 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard metric shoulder screw for use in machine frames, fixtures, and mechanical assemblies requiring an M16x2 thread and a 20 mm shoulder diameter per ISO 7379 and ASME\/ANSI B18.3.3.M dimensional standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or mechanical assembler familiar with high-strength metric fasteners. Ensure the mating bore is machined to the appropriate tolerance for the 20 mm shoulder before installation. Use a calibrated hex key sized for the socket drive and apply a suitable thread lubricant or anti-seize compound to the M16x2 threads. Do not exceed the torque capacity of the 12.9 grade material, and never substitute a lower-grade fastener in an application sized for this part.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Shoulder Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 100 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M16x2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 29.67 to 30 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 13.73 to 14 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 12.9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME\/ANSI B18.3.3.M, BS 4168, ISO 7370, ISO 7379\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 537308BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699686375730,"sku":"537308BR","price":78.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4fdb013d332048d12ea5cb6aa9a49042_766a1b60-208c-4ef4-91e1-8aa79546386d.jpg?v=1788379198","url":"https:\/\/voomisupply.com\/products\/value-collection-537308br-shoulder-screw-m16x2-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
