Manufactured from Grade 8 alloy steel with a brass soft tip, this fastener applies clamping force against a shaft or surface without scoring or damaging the mating part. The hex drive socket accepts a standard hex key for installation and removal. Grade 8 alloy steel construction provides the tensile strength needed for high-load fastening tasks in mechanical assemblies, tooling fixtures, and equipment maintenance work.\u003c\/p\u003e\n\u003cp\u003eThis set screw is used in light mechanical assemblies where a 4-40 UNC or UNF threaded hole is present and shaft or component protection is a priority. The brass soft tip is commonly specified in precision instrument work, motor shaft collars, encoder mounts, and similar applications where a hardened point would damage a polished or soft mating surface. Machinists, maintenance technicians, and mechanical assemblers typically install this fastener in production and repair settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel body for high tensile strength in a small-diameter fastener\u003c\/li\u003e\n  \u003cli\u003eBrass soft tip prevents scoring or marring of shafts and mating surfaces\u003c\/li\u003e\n  \u003cli\u003eHex drive socket accepts standard hex keys for installation in tight clearances\u003c\/li\u003e\n  \u003cli\u003e4-40 UNC\/UNF thread standard for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch thread engagement length measured along the full thread\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension replacement or stock fastener for any mechanical assembly using a 4-40 UNC or UNF tapped hole that requires a soft-tip set screw.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a hex key sized for a 4-40 set screw socket. De-energize or lock out any rotating equipment before installing or adjusting set screws on shaft collars or couplings. Do not exceed the rated torque range for a 4-40 Grade 8 fastener, and ensure the brass tip is properly seated against the mating surface before final tightening. General industrial fastener practice and applicable equipment manufacturer guidelines should be followed during installation.\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\u003eLength\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC \/ UNF\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\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\u003eTip Material\u003c\/strong\u003e: Brass\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-440-250-AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700603945266,"sku":"BT-440-250-AS","price":1054.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97947a319a28f7a6d722d400fd67a239.jpg?v=1788392577","url":"https:\/\/voomisupply.com\/products\/value-collection-bt-440-250-as-set-screw-4-40-x-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
