Marson M47871 Threaded Insert 5/16-18 Steel Thread-sert

Product Description

The MARSON M47871 is a steel Thread-Sert threaded insert designed to create strong, load-bearing internal threads in thin materials, sheet metal, and panels where a standard nut cannot be used. It features a 5/16-18 thread form with an overall length of 0.615 inches and installs into a 0.500-inch diameter hole. The 0.537-inch head diameter seats flush or near-flush against the workpiece surface. Fabricators and field service technicians use Thread-Sert inserts when parent material lacks the thickness or integrity for tapped threads.

Thread-Sert inserts like the M47871 are common in HVAC panel assembly, electrical enclosure fabrication, and mechanical equipment service work. They are installed where fastener pull-out resistance is required in light-gauge steel, aluminum, or composite panels. The 5/16-18 thread size suits medium-duty fastening applications across a wide range of trade and light industrial maintenance scenarios. This insert ships in a package quantity of 25 units per pack.

Key Features

• 5/16-18 unified coarse thread form provides strong, reusable internal threads in thin materials
• 0.615-inch overall length suits standard light-gauge panel and sheet metal applications
• 0.500-inch installation hole diameter for straightforward drilling with standard twist bits
• 0.537-inch head diameter seats securely against the workpiece to resist pull-through
• Steel construction for durability in mechanical and HVAC service environments
• Package quantity of 25 supports job-lot use and service truck stocking

Compatibility

Designed as an OEM-style threaded insert replacement or new-installation fastener for light-gauge panels and sheet metal assemblies requiring 5/16-18 internal threads in a 0.500-inch hole.

Installation Notes

Thread-Sert inserts are typically installed by HVAC technicians, electricians, or sheet metal fabricators using a compatible mandrel installation tool or rivet-nut setting tool. Ensure the parent material hole is drilled to the specified 0.500-inch diameter and is free of burrs before installation. De-energize all electrical systems and depressurize mechanical systems before servicing any panel or enclosure. Follow applicable NEC or equipment manufacturer guidelines for fastener installation in electrical enclosures.
