It measures 3\/8 inches in thread length and is driven by a hex (Allen) key. The brass tip protects mating shaft surfaces from damage during tightening, making this screw suitable for applications where marring or scoring of the contact surface must be avoided. Machinists, millwrights, and mechanical assembly technicians commonly install this style of fastener to secure collars, knobs, pulleys, and similar components onto shafts without permanent deformation of the shaft material.\u003c\/p\u003e\n\u003cp\u003eThis set screw is intended for light-duty mechanical assemblies requiring a fine 4-40 thread. The soft brass tip makes it well suited for use against hardened or polished shafts where surface integrity is critical. Grade 18-8 stainless steel construction provides corrosion resistance in moderately humid or washdown environments. Typical installations include precision instruments, HVAC damper assemblies, small motor shaft collars, and general machine shop fabrication where a reusable, non-marring fastener is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSoft brass tip prevents scoring or marring of shaft surfaces during tightening\u003c\/li\u003e\n  \u003cli\u003eGrade 18-8 stainless steel body offers corrosion resistance in humid or light washdown environments\u003c\/li\u003e\n  \u003cli\u003e4-40 UNC thread standard for fine-pitch, light-duty mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003eHex drive (Allen key) for precise torque application in tight or recessed spaces\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch thread length provides adequate engagement depth for standard collar and hub applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 UNC hex-drive soft-tip set screw for general mechanical assembly applications requiring a non-marring fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using the correct size hex (Allen) key to avoid rounding the drive recess. Ensure the shaft and collar are clean and properly aligned before tightening. De-energize any associated equipment completely before servicing shaft-mounted components. Do not overtighten, as the brass tip will deform under excessive load and reduce holding effectiveness.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC \/ UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3\/8 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: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\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: BT-440-375-SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689654812978,"sku":"BT-440-375-SS","price":860.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77fc27a83b94fb80fbe530807b1a44f2.jpg?v=1788262499","url":"https:\/\/voomisupply.com\/products\/value-collection-bt-440-375-ss-set-screw-4-40-x-3-8-in-ss-18-8","provider":"Voomi Supply","version":"1.0","type":"link"}
