It is driven by a 5\/32-inch hex key and conforms to ASME\/ANSI B18.3 and ASTM F912 standards. Cup point set screws bite into a shaft or workpiece surface to resist rotation and axial movement, making them a standard fastener in mechanical assemblies, rotating equipment, and fixture work. Machinists, millwrights, and maintenance technicians install these fasteners when securing collars, pulleys, gears, and hubs to shafts where a headless profile is required to keep the fastener below the surface.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for general industrial and mechanical assembly applications where a fully threaded, headless fastener is needed. The 5\/16-18 UNC thread pitch is a common coarse-thread designation found across a wide range of mechanical components. The cup point geometry concentrates clamping force on a small contact area, providing strong holding power against shaft surfaces without requiring a through-hole. These fasteners are sold in multiples of 100 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003eCup point geometry bites into shaft material to resist rotation and axial movement\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex drive compatible with standard hex keys and Allen drivers\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread conforms to ASME\/ANSI B18.3 and ASTM F912\u003c\/li\u003e\n  \u003cli\u003eHeadless profile sits flush or below the surface of the mating component\u003c\/li\u003e\n  \u003cli\u003eFractional inch measurement type for straightforward sizing in standard applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stock fastener for mechanical assemblies requiring a 5\/16-18 UNC headless cup point set screw with a 5\/32-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\/32-inch hex key or Allen driver. De-energize or lock out rotating equipment before installing or removing set screws per applicable LOTO procedures. Ensure the mating shaft and threaded bore are clean and free of debris before threading the fastener. Do not exceed the torque rating of the alloy steel material or the thread engagement capacity of the receiving component.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 3\/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\u003eHex Key Size\u003c\/strong\u003e: 5\/32 inches (0.1563 inches decimal)\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  \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: 0.00457 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161505\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: 101383P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721403203890,"sku":"101383P","price":2953.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/42a5702d75ae82051a03eb629bb413c8.jpg?v=1788577101","url":"https:\/\/voomisupply.com\/products\/value-collection-101383p-set-screw-5-16-18-x-3-8-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
