It features a knurled cup point, which bites into the mating surface to resist rotation and axial movement without requiring a separate locking element. Turned with a 5\/64 inch hex key, this screw carries an 8-32 UNC thread and measures 1\/2 inch in overall length. It is manufactured from Grade 8 alloy steel, meeting ASME\/ANSI B18.3 and ASTM F912 standards. Electricians, HVAC technicians, and mechanical tradespeople use this fastener type when assembling or servicing equipment with set-screw retained components.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for light-duty mechanical assemblies found in residential and commercial HVAC equipment, electrical enclosures, motors, and general industrial machinery. The 8-32 UNC thread is a common size in small-component assemblies, making this fastener a frequent replacement and maintenance item across multiple trades. It is sold individually, with a minimum order quantity of 100 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKnurled cup point provides positive grip on shaft surfaces to resist rotation and axial slip\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction delivers higher tensile strength than standard steel set screws\u003c\/li\u003e\n  \u003cli\u003e5\/64 inch hex drive accepts standard hex keys and ball-end drivers\u003c\/li\u003e\n  \u003cli\u003e8-32 UNC thread is a widely used size across HVAC, electrical, and mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch overall length suits shallow hub and collar applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 8-32 UNC set screw suitable for any application requiring a knurled cup point headless fastener conforming to ASME\/ANSI B18.3 and ASTM F912 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 5\/64 inch hex key or ball-end driver.
