Manufactured from Grade 8 alloy steel, this screw delivers high tensile strength suited to demanding industrial and trade applications. It features a 1\/4-28 UNF thread form with an overall length of 1\/4 inches and is driven by a 1\/8-inch hex key. Conforming to ASME\/ANSI B18.3 and ASTM F912 standards, the 101337PR is a precision fastener appropriate for machinists, millwrights, and maintenance technicians working on shafts, collars, pulleys, and similar components.\u003c\/p\u003e\u003cp\u003eThis set screw is used wherever a headless fastener must lock a component onto a shaft or secure a part within a bore. The cup point geometry bites into the mating surface to resist rotational and axial movement, making it common in motor shaft assemblies, conveyor components, and mechanical drive systems. It is sold individually but carries a minimum order quantity of 100 pieces, making it suitable for shop stock, MRO inventory, or production-level fastener needs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCup point tip bites into shaft surface for positive locking without a projecting head\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction for high tensile and torsional strength\u003c\/li\u003e\n\u003cli\u003e1\/4-28 UNF thread form for fine-pitch engagement and precise axial positioning\u003c\/li\u003e\n\u003cli\u003e1\/8-inch hex drive compatible with standard hex keys and Allen wrenches\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and mechanical standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or stock fastener for any mechanical assembly requiring a 1\/4-28 UNF headless cup point set screw with a 1\/8-inch hex drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 1\/8-inch hex key or Allen wrench. De-energize and lock out any equipment before installing or removing set screws on rotating shafts or driven components. Do not over-torque; back the screw out fully before repositioning a shaft collar to avoid thread damage. Follow applicable ASME fastener torque guidelines for the thread size and grade when precise clamping force is required.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1\/4 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\u003eThread Standard\u003c\/strong\u003e: UNF\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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161505\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 101337PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692950323506,"sku":"101337PR","price":2051.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b938c9341550a9102a69119b7750ccf8.jpg?v=1788305333","url":"https:\/\/voomisupply.com\/products\/value-collection-101337pr-set-screw-1-4-28-x-1-4-in-cup-point-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
