Cone point set screws are designed to bite into or permanently indent a mating surface, providing strong resistance to rotational and axial movement. This fastener accepts a 5\/32-inch hex key and conforms to ASME\/ANSI B18.3 and ASTM F912 standards, making it a reliable choice for precision mechanical assemblies. Electricians, millwrights, pipefitters, and HVAC technicians regularly use set screws of this type when securing collars, couplings, pulleys, and shaft-mounted components.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for both residential and light commercial mechanical assemblies where a permanent or semi-permanent locking action against a shaft or bore surface is required. The cone point geometry concentrates clamping force at a single point, making it particularly effective on hardened shafts or in applications where the fastener will not be frequently removed. It is commonly installed in blower wheel hubs, fan blade collars, motor shaft couplings, and similar rotating drive components found in HVAC, plumbing, and general mechanical systems.\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\u003eCone point geometry provides aggressive bite and strong axial holding force\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex socket drive compatible with standard hex keys and L-wrenches\u003c\/li\u003e\n  \u003cli\u003eUNC thread standard (5\/16-18) for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eCompact 1\/2-inch overall length suits confined installation spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC set screw for use in any tapped hole or threaded collar meeting that thread specification.

De-energize and lock out any rotating equipment before installing or removing set screws per applicable lockout\/tagout procedures. Cone point set screws create a permanent indentation in the mating surface and are not intended for frequent removal. Torque to the fastener manufacturer recommendation for the thread size and grade; do not over-drive, as this can damage the hex socket or the mating shaft surface.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5 inches (overall)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cone Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 5\/32 inches (0.1563 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\u003eThread Standard\u003c\/strong\u003e: UNC\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\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: 121145PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699638337842,"sku":"121145PR","price":3923.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/26f947dd114645702f21851a7c647c2c.jpg?v=1788378547","url":"https:\/\/voomisupply.com\/products\/value-collection-121145pr-set-screw-5-16-18-x-1-2-in-cone-point","provider":"Voomi Supply","version":"1.0","type":"link"}
