The screw features a 1\/4-20 UNC\/UNF thread and measures 1\/2 inch in threaded length. Drive engagement is through a hex socket. Grade 8 alloy steel construction provides high tensile and torsional strength, while the brass tip compresses slightly under load to protect softer shaft materials from damage. This type of fastener is installed by licensed trades and skilled technicians across mechanical, HVAC, and industrial equipment assemblies.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for use in mechanical power transmission components such as collars, pulleys, sprockets, and hubs where a non-damaging clamping point is required. The soft brass tip is particularly appropriate when the mating shaft is made of aluminum, brass, or a finished steel surface that must not be scored. Typical applications include HVAC blower wheel hubs, fan blade collars, and light-duty shaft retention in residential and commercial equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel body for high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003eSoft brass tip prevents marring or scoring of mating shaft surfaces\u003c\/li\u003e\n  \u003cli\u003eHex socket drive for standard hex key installation and removal\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 thread compatible with UNC and UNF standards\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch threaded length suits shallow hub and collar applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fastener for mechanical assemblies requiring a 1\/4-20 x 1\/2 inch soft-tip set screw with hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a hex key of the appropriate inch size for the socket. De-energize and lock out all equipment before accessing rotating components. Do not overtighten, as the brass tip can deform and lose holding force if excessive torque is applied. Follow the equipment manufacturer's torque guidelines where available, and confirm shaft cleanliness before seating the screw.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\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: 0.5 inches (threaded length)\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\u003eDrive Type\u003c\/strong\u003e: Hex Socket\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\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-1420-500-AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699940458802,"sku":"BT-1420-500-AS","price":1335.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9196ec4d2d76b46ef2671bb5be4c6097.jpg?v=1788383730","url":"https:\/\/voomisupply.com\/products\/value-collection-bt-1420-500-as-set-screw-1-4-20-x-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
