Marson M47840 Thread-sert Threaded Insert 10-32 Pack 100

Product Description

The MARSON M47840 is a Thread-Sert threaded insert designed to install new 10-32 threads into thin-gauge base materials where conventional tapping is not practical. With an overall length of 0.375 inches, a required hole diameter of 0.281 inches, and a head diameter of 0.314 inches, this insert is made from steel for reliable holding strength in demanding fastening applications. Licensed HVAC, electrical, and mechanical contractors use threaded inserts like this one when securing control panels, enclosures, brackets, and sheet metal assemblies that require clean, load-bearing internal threads without welding or forming.

This insert is suited for residential and commercial applications wherever a permanent, threaded anchor point must be added to sheet metal, thin steel, or similar substrates. Common install scenarios include electrical enclosure assembly, HVAC control panel fabrication, and mechanical equipment bracket mounting. The 10-32 thread size is a standard fastener pitch widely used in control boards, fan assemblies, and light-gauge structural components across the trades. This SKU ships in a package quantity of 100, making it practical for production assembly or ongoing service stock.

Installation Notes

Threaded inserts of this type are installed by sheet metal fabricators, HVAC technicians, electricians, and mechanical contractors using a standard Thread-Sert installation tool or compatible setting mandrel. Always drill the correct pilot hole diameter before installation and deburr the hole to ensure proper head seating. Verify that base material thickness is within the grip range of the insert before driving. Follow applicable NEC or equipment manufacturer guidelines when installing inserts in electrical enclosures or live equipment panels.
