Set screws are headless fasteners used to secure a component — such as a collar, pulley, or gear — onto a shaft by applying direct pressure at the point of contact. The cup point design bites into the mating surface to resist rotation and axial movement. Driven with a 1\/8-inch hex key, this fastener meets ASME\/ANSI B18.3 and ASTM F912 standards. It is appropriate for mechanical assemblies requiring reliable holding force in a compact, flush-mount form factor. Sold individually; minimum order quantity is 100 pieces.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for light industrial, mechanical maintenance, and OEM assembly applications where a flush or below-surface fastener is required. The 1\/4-28 thread is a fine-pitch unified thread (UNF), offering higher thread engagement and resistance to loosening compared to coarse-pitch alternatives. Typical applications include shaft collars, set-screw hubs, couplings, and similar mechanical drive components across HVAC equipment, pumps, and general machinery.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry bites into shaft surface to resist axial and rotational movement\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction provides high tensile strength and durability\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 fine-pitch UNF thread for improved holding force and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch internal hex drive for use with standard hex keys or Allen wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush or below surface for clearance-sensitive assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any mechanical assembly requiring a 1\/4-28 threaded set screw with a cup point. Verify thread size, length, and point type against the existing hardware specification before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist, millwright, or mechanical technician using a 1\/8-inch hex key. De-energize and lock out any rotating equipment before servicing components secured by set screws. Apply appropriate thread-locking compound if vibration is a concern, and torque to the value specified by the equipment manufacturer or applicable engineering specification — do not over-tighten, as cup point set screws can deform the mating shaft surface. Inspect the seating surface for burrs or contamination before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28\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: 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: 1\/8 inches (0.1250 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: 0.00305 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161505\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 101341P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699003064626,"sku":"101341P","price":2628.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0cb30951ed2279db75a365fb4c0c2e7a.jpg?v=1788371026","url":"https:\/\/voomisupply.com\/products\/value-collection-101341p-set-screw-1-4-28-x-3-8-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
