Set screws are headless fasteners that thread fully into a tapped hole and bear directly against a mating surface to lock a component — such as a collar, gear, or pulley — onto a shaft. This screw measures 5\/8 inch in length (overall) with a 5\/16-inch hex drive and conforms to ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards. The cup point geometry creates a ring-shaped bite into the shaft surface, providing strong axial and rotational resistance under load. Machinists, millwrights, and maintenance technicians working in general industrial and mechanical assembly applications install this fastener.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for general industrial machinery, power transmission assemblies, and mechanical component retention where a 5\/8-18 fine-thread engagement is required. The fine UNF thread pitch provides higher thread engagement per unit length compared to coarse thread, making it a common choice where vibration resistance or finer torque adjustment is needed. Typical applications include locking shaft collars, sprockets, couplings, and hubs in light to heavy-duty mechanical assemblies. Installation requires a 5\/16-inch hex key.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry bites into shaft surface for strong axial and rotational holding force\u003c\/li\u003e\n  \u003cli\u003e5\/8-18 UNF fine thread for increased thread engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and hardness requirements\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex drive compatible with standard hex keys and L-wrenches\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 and ASTM F912 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stock fastener for any mechanical assembly requiring a 5\/8-18 UNF cup point set screw with a 5\/16-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 5\/16-inch hex key or Allen wrench. Ensure the mating threaded hole is clean and free of debris before installation. De-energize and lock out all rotating equipment before installing or removing set screws in power transmission applications. Do not exceed the torque capacity of the alloy steel fastener by using extension tools on the hex key.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5\/8 inches (overall)\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\u003eDrive Size\u003c\/strong\u003e: 5\/16 inches\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\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM F912\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 101635PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51708981903666,"sku":"101635PR","price":22.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c97bc3daf5e50f6a51ff76c11e013eeb.jpg?v=1788449550","url":"https:\/\/voomisupply.com\/products\/value-collection-101635pr-set-screw-5-8-18-x-5-8-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
