The mandrel serves as the threaded drive component that engages the rivet nut or threaded insert during the setting process, allowing the tool to pull and deform the fastener body into the base material. This is a hand tool accessory used in metal fabrication, assembly, and maintenance work where threaded fasteners must be installed into thin-gauge sheet metal or panels without access to the back side. Technicians and tradespeople working with 3\/8-16 threaded inserts will need this mandrel as a matched replacement or additional-size accessory for their 39300 tool.\u003c\/p\u003e\u003cp\u003eThis mandrel is suited for applications requiring a 3\/8-16 thread engagement in rivet nut installation work. Typical scenarios include HVAC equipment panel assembly, electrical enclosure fabrication, and general sheet metal work where blind-side fastener installation is required. It is sold individually and is intended as a direct accessory component for the MARSON 39300 insert tool platform.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-16 thread size for compatibility with standard 3\/8-16 rivet nuts and threaded inserts\u003c\/li\u003e\n\u003cli\u003eDesigned as a matched mandrel accessory for the MARSON 39300 installation tool\u003c\/li\u003e\n\u003cli\u003eEnables blind-side threaded insert installation in thin-gauge materials\u003c\/li\u003e\n\u003cli\u003eLightweight construction at 0.3 pounds for easy handling during repetitive install work\u003c\/li\u003e\n\u003cli\u003eSold as a single unit for targeted size replacement or expansion of an existing tool set\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the MARSON 39300 rivet nut and threaded insert installation tool.

Verify the mandrel thread engagement is fully seated and snug before applying setting force. Do not overtighten or use the mandrel with threaded insert sizes or thread pitches other than 3\/8-16, as mismatched threads will damage both the mandrel and the fastener. Inspect the mandrel threads periodically for wear and replace as needed to maintain consistent setting performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: Rivet Nut and Threaded Insert Tools\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MARSON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: M39360\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MARSON","offers":[{"title":"Default Title","offer_id":68260733419826,"sku":"M39360","price":50.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d57663017130c10c5a06ad21445e156d.jpg?v=1793674862","url":"https:\/\/voomisupply.com\/products\/marson-m39360-insert-tool-mandrel-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
