Set screws of this type are used to secure a component — such as a collar, gear, or pulley — against a shaft without a protruding head. The nylon tip protects the mating surface from marring while still providing positive clamping force. The 3\/16-inch thread length suits compact assemblies where space is constrained. This fastener is installed by maintenance technicians, millwrights, and mechanical assemblers working across HVAC equipment, motors, and general industrial machinery.\u003c\/p\u003e\u003cp\u003eThis set screw is suited for light-duty mechanical assemblies requiring a non-marring clamping point. Typical applications include shaft collars on small motors, setscrew-style shaft couplings, and precision instrument components where surface protection on the mating shaft is required. The 4-40 thread size is common in miniature and instrumentation-grade assemblies. The UNC and UNF dual-standard thread designation provides flexibility across both coarse and fine-thread tapped holes of the same nominal diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSoft nylon tip protects mating shaft surfaces from damage during clamping\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel body delivers high tensile and torsional strength for the 4-40 thread class\u003c\/li\u003e\n\u003cli\u003eHex drive socket allows installation with a standard hex key or Allen wrench\u003c\/li\u003e\n\u003cli\u003eUNC and UNF thread standard compatibility broadens fitment across tapped hole types\u003c\/li\u003e\n\u003cli\u003e3\/16-inch thread length suits compact, space-constrained mechanical assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 4-40 hex-drive soft-tip set screw for use in any tapped 4-40 UNC or UNF threaded hole requiring a non-marring nylon tip point.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed using a correctly sized hex key; use of an undersized key risks rounding the drive socket. De-energize and lock out any motor or rotating equipment before installing or adjusting set screws. Apply only enough torque to achieve positive clamping without stripping the small 4-40 thread. Inspect the nylon tip for wear or deformation periodically, particularly in high-vibration environments.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Soft Tip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Nylon\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\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: NT-440-187-AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51708266676530,"sku":"NT-440-187-AS","price":1022.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/527b17b72bd373a0dbee50f543028ec7.jpg?v=1788445165","url":"https:\/\/voomisupply.com\/products\/value-collection-nt-440-187-as-set-screw-4-40-soft-tip","provider":"Voomi Supply","version":"1.0","type":"link"}
