It features a 1\/4-20 UNC\/UNF thread and measures 5\/16 inches in length. The brass tip contacts the mating surface, reducing the risk of surface damage on shafts, rods, or other precision components. Drive engagement is via hex socket. This fastener is installed by machinists, maintenance technicians, and trade professionals working on motors, couplings, pulleys, collars, and similar mechanical hardware requiring positive axial or radial locking without permanent surface deformation.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for residential and light commercial mechanical applications where a soft-tip point is required to grip a shaft or component without gouging the surface. Typical installations include motor shaft collars, shaft couplings, handwheels, fan pulleys, and similar rotating or sliding assemblies across HVAC equipment, pump drives, and general mechanical systems. The 1\/4-20 thread size is one of the most common inch-series thread standards, making this screw broadly applicable across a wide range of equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction provides high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003eBrass soft tip reduces surface marring on shafts and precision components\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC\/UNF thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eHex socket drive for use with standard hex keys or Allen wrenches\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch thread length suits shallow to mid-depth tapped hole applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-thread replacement or stock set screw for any 1\/4-20 tapped hole application requiring a soft-tip, hex-drive fastener in Grade 8 alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fastener is typically installed by machinists or maintenance technicians using a hex key or Allen wrench sized for the hex socket. Ensure the mating tapped hole is clean and free of debris before installation. Do not exceed the rated torque range for 1\/4-20 Grade 8 fasteners, and verify thread engagement depth is adequate for the load being applied. Avoid overtightening, which can damage the brass tip or strip the tapped hole.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC \/ UNF\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\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\u003eTip Material\u003c\/strong\u003e: Brass\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BT-1420-312-AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51713598751026,"sku":"BT-1420-312-AS","price":1281.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/753eff7328683dd040753c3069fb033b.jpg?v=1788494534","url":"https:\/\/voomisupply.com\/products\/value-collection-bt-1420-312-as-set-screw-1-4-20-x-5-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
