Marson M39354 Insert Tool Mandrel 6-32

Product Description

The MARSON M39354 is a 6-32 thread mandrel designed for use with threaded insert installation tools. The mandrel threads onto the nose of a compatible insert tool and engages the rivet nut or threaded insert during the pulling cycle, allowing the installer to set the fastener accurately in sheet metal, plastics, and composite panels. At 0.3 pounds, it is a lightweight hand-tool accessory suited to bench work and field installation. HVAC fabricators, electricians, and general trade mechanics who work with blind fastening applications will find this mandrel a necessary consumable for maintaining a complete insert tool kit.

This mandrel is intended for use in light fabrication and assembly environments where 6-32 threaded inserts are installed into thin-gauge materials. Common applications include electrical enclosures, HVAC equipment panels, control boxes, and other assemblies where a permanent threaded anchor is needed in a blind or thin-wall substrate. The mandrel is a replaceable component - working mandrels wear over time with repeated cycling and should be inspected regularly for thread damage.

Designed for use with the MARSON 39300 threaded insert tool. Intended for setting 6-32 threaded inserts and rivet nuts in compatible installation tools that accept this mandrel size.

Installation Notes

Thread the mandrel securely onto the nose assembly of the insert tool before operation. Verify thread engagement is complete before cycling the tool to avoid cross-threading or mandrel failure. Mandrels should be replaced when thread wear is visible or when the tool no longer sets inserts to full specification. No power source is required for manual insert tools, but always follow the tool manufacturer's operating instructions for proper nose assembly and mandrel torque guidance.
