It measures 1\/16 inch in overall length and uses a hex drive requiring a 0.035-inch hex key. The 1-72 thread designation follows UNF (Unified National Fine) standards. Set screws of this type are used to lock rotating components onto shafts or to fix two mating parts in position without a protruding head. The 18-8 stainless steel construction provides corrosion resistance suitable for general industrial, HVAC, plumbing, and light mechanical assembly applications. Installation is performed by trade mechanics and maintenance technicians using standard hex key tooling.\u003c\/p\u003e\u003cp\u003eThis set screw is suited for fine-thread applications where a flush, headless fastener is required. The cup point geometry bites into the mating surface to resist rotation and axial movement. Common install scenarios include securing collars, pulleys, and small mechanical components in HVAC equipment, pumps, and motors. The small No. 1-72 thread size makes it appropriate for compact assemblies where standard coarse-thread fasteners are too large. This SKU is sold individually but carries a minimum order quantity of 100 pieces per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCup point geometry bites into mating surfaces for positive holding force\u003c\/li\u003e\n\u003cli\u003e18-8 stainless steel provides corrosion resistance in damp or chemically exposed environments\u003c\/li\u003e\n\u003cli\u003eUNF No. 1-72 fine thread for precise engagement in compact assemblies\u003c\/li\u003e\n\u003cli\u003eHex drive socket accepts a 0.035-inch hex key for installation in tight spaces\u003c\/li\u003e\n\u003cli\u003eHeadless design sits flush or below the surface of the mating component\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNF No. 1-72 headless cup point set screw suitable for use in any threaded bore of matching pitch and diameter in mechanical, HVAC, or light industrial assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 0.035-inch hex key. Ensure the mating threaded bore is clean and free of debris before driving the screw. De-energize or lock out any equipment before accessing internal mechanical components. Do not overtighten, as the small thread size is susceptible to galling in stainless-to-stainless applications; applying an anti-seize compound is common practice.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: No. 1-72\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cup\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 0.035 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.001 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: R40311449\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702792323378,"sku":"R40311449","price":7200.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8c58ee4ef81001160b74edbb398dc7e9.jpg?v=1788413340","url":"https:\/\/voomisupply.com\/products\/value-collection-r40311449-set-screw-1-72-cup-point-18-8","provider":"Voomi Supply","version":"1.0","type":"link"}
