Set screws of this type are used to secure a component — such as a collar, pulley, gear, or sprocket — onto a shaft without a protruding head. The hex drive socket accepts a standard hex key for installation and removal. The brass soft tip protects the mating shaft surface from marring or galling, making this screw a common choice where shaft integrity must be preserved during adjustment or service. This fastener suits mechanical assembly and maintenance work across HVAC, industrial, and general trade applications.\u003c\/p\u003e\u003cp\u003eThis set screw is suited for residential and commercial mechanical assemblies where a flush, low-profile fastener is required and shaft-surface protection is a priority. Typical install scenarios include securing drive pulleys on blower assemblies, positioning collars on motor shafts, and locking hubs or couplings in place. The UNC thread standard ensures compatibility with standard inch-series tapped holes sized 5\/16-18. Sold individually with a minimum order quantity of 10 units per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSoft brass tip minimizes surface damage and galling on mating shafts\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction provides high tensile and torsional strength\u003c\/li\u003e\n\u003cli\u003eHex socket drive accepts standard hex keys for installation in tight clearances\u003c\/li\u003e\n\u003cli\u003e5\/16-18 UNC thread fits standard inch-series tapped holes\u003c\/li\u003e\n\u003cli\u003eHeadless design sits flush with or below the surface of the workpiece\u003c\/li\u003e\n\u003cli\u003eThread length measured as full fastener length: 5\/16 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard inch-series 5\/16-18 UNC tapped holes where a soft-tip set screw is required to secure components to a shaft without marring the shaft surface.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSet screws of this type are installed by licensed millwrights, HVAC technicians, and maintenance mechanics using a properly sized hex key or hex bit driver. De-energize all equipment and lock out power before disassembling shaft-mounted components. Avoid over-tightening, which can deform the brass tip and reduce its shaft-protection benefit. Ensure the tapped hole is clean and free of debris before threading the screw in to prevent cross-threading.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Soft Tip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Brass\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: Grade 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC \/ UNF\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: BT-51618-312-AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701073609010,"sku":"BT-51618-312-AS","price":1381.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3d1ab607cb7bf1a1f2e344a2fc05b0b7.jpg?v=1788397856","url":"https:\/\/voomisupply.com\/products\/value-collection-bt-51618-312-as-set-screw-5-16-18-x-5-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
