Marson M47920 Threaded Insert 8-32 3/8 Inch Aluminum

Product Description

The MARSON M47920 is an aluminum Thread-Sert threaded insert designed to create strong, permanent 8-32 internal threads in thin-gauge sheet metal, plastic panels, and other base materials that cannot hold a standard machine screw thread on their own. At 3/8 inch overall length with a 1/4 inch installation hole diameter and a 0.282 inch head diameter, this insert installs from one side of the workpiece, making it well suited for applications where only one side of the material is accessible. HVAC cabinet fabricators, electrical enclosure builders, and sheet metal mechanics commonly use Thread-Serts to add reliable fastening points without welding or tapping.

Thread-Serts see regular use in light commercial and residential HVAC equipment, electrical control panels, refrigeration cabinets, and general sheet metal assemblies. The insert is set using a standard hand or pneumatic rivet nut tool, collapsing the body behind the panel to clamp the material between the flange and the collapsed shank. This package contains 100 inserts, making it practical for production runs or service van restocking. Applications include mounting control boards, brackets, access panels, and covers where a machine screw connection is required in thin material.

Key Features

• 8-32 internal thread provides a standard machine screw fastening point in thin-wall materials
• 3/8 inch overall length suits typical sheet metal gauges found in HVAC and electrical enclosures
• 1/4 inch installation hole diameter allows quick drilling or punching to the correct prep size
• 0.282 inch head diameter seats flush against the panel face to minimize protrusion
• Aluminum construction offers corrosion resistance and light weight suitable for indoor cabinetry
• Package of 100 supports production and service stocking at a single-unit minimum order

Compatibility

Designed as an OEM-style replacement or new-installation threaded insert for thin sheet metal and panel applications requiring an 8-32 machine screw thread with a 1/4 inch prep hole.

Installation Notes

Thread-Serts are installed by sheet metal mechanics and HVAC technicians using a rivet nut setting tool rated for the insert size. The workpiece should be drilled or punched to exactly 1/4 inch diameter before installation. Deburr the hole edge to ensure the flange seats flat. Do not overtighten the setting tool, as over-driving will strip the thread or crack the aluminum body.
