Manufactured from Grade 8 alloy steel, this screw delivers high tensile strength suitable for demanding industrial and trade applications. The 5\/8-18 UNF thread provides a fine-pitch engagement for precise torque control and vibration resistance. At 1 inch in overall length, it is driven with a 5\/16-inch hex key and conforms to ASME\/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, and maintenance technicians use this fastener for shaft collars, pulleys, gears, and similar components where a headless profile is required.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for use in rotating equipment, shaft-to-hub connections, and mechanical assemblies across industrial, HVAC, and equipment maintenance applications. The cup point tip bites into the mating surface to resist rotation and axial movement under load. It is appropriate for use in both light-duty and heavy-duty mechanical assemblies where a fine-thread alloy steel fastener is specified. Minimum order quantity is 10 units, sold as individual pieces per package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry bites into mating surface for strong axial and rotational holding force\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction provides high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e5\/8-18 UNF fine-pitch thread for precise engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex drive compatible with standard hex keys and L-wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eHeadless profile eliminates snag points in rotating or close-clearance assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-specification fastener for any mechanical assembly requiring a 5\/8-18 UNF cup point set screw in Grade 8 alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or qualified maintenance technicians using a 5\/16-inch hex key or L-wrench. De-energize and lock out all rotating equipment before accessing shaft collars or hubs. Ensure the mating shaft surface is clean and free of debris before seating the cup point. Do not exceed the torque rating specified for Grade 8 fasteners of this thread size as referenced in applicable mechanical standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1 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: 5\/16 inch (0.3125 inch)\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: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM F912\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 101637PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716361584946,"sku":"101637PR","price":25.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f6b568d236207f770027b01015df2d2.jpg?v=1788524894","url":"https:\/\/voomisupply.com\/products\/value-collection-101637pr-set-screw-5-8-18-x-1-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
