Threaded Insert with Tang

Updated: 2026-09-13

Overview

The Threaded Insert with Tang is a specialized fastener designed to provide durable internal threads in materials that lack the strength to maintain threads independently. It consists of a cylindrical body with external threads for insertion into a pre-drilled hole and internal threads to accommodate screws or bolts. The tang, a small protruding feature, aids in installation and is typically broken off after insertion. This component is widely used in industries such as automotive, aerospace, and electronics, where repeated assembly and disassembly are common. By reinforcing the thread integrity, it extends the lifespan of the host material and ensures reliable fastening in demanding applications.

Structure and Working Principle

The Threaded Insert with Tang features a helical design with external threads that bite into the host material, creating a secure fit. The internal threads are precision-cut to match standard screw or bolt sizes, ensuring compatibility. The tang, located at one end, is used to drive the insert into the hole using a specialized tool or installation mandrel. During installation, the external threads deform the host material slightly, creating a tight mechanical bond. Once fully seated, the tang is snapped off, leaving a clean, flush surface. This design ensures high pull-out resistance and load-bearing capacity, making it ideal for applications where thread durability is critical.

Key Features

Threaded Inserts with Tang are known for their high strength and durability, often made from materials like stainless steel or brass to resist corrosion and wear. The external threads are typically coarse to grip the host material securely, while the internal threads are fine for precise fastening. The tang feature simplifies installation, reducing the risk of misalignment or damage to the host material. These inserts are available in various sizes and thread pitches to accommodate different applications. Their ability to distribute load evenly across the host material makes them a preferred choice for reinforcing weak or soft substrates.

Application Areas

Threaded Inserts with Tang are extensively used in industries requiring robust and reusable threads. In automotive manufacturing, they reinforce threads in engine blocks, transmission housings, and other critical components. The aerospace industry relies on them for lightweight yet durable fastening solutions in aircraft structures. Electronics manufacturers use these inserts to create sturdy threads in plastic or aluminum enclosures, ensuring reliable screw retention. They are also common in furniture assembly, where they prevent stripping in wood or composite materials. Their versatility makes them suitable for any application where thread integrity is paramount.

Maintenance and Precautions

Proper installation is crucial for the performance of Threaded Inserts with Tang. Ensure the pre-drilled hole matches the insert's size and depth to avoid misalignment or insufficient grip. Use the correct installation tool to prevent damage to the insert or host material. Avoid over-tightening screws or bolts, as this can strip the internal threads. For high-load applications, consider using inserts made from high-strength materials like stainless steel. Regular inspection for wear or corrosion is recommended, especially in harsh environments, to maintain thread integrity over time.

B2B Procurement Guide

When procuring Threaded Inserts with Tang, prioritize suppliers with a proven track record in quality and reliability. Specify material requirements based on the application environment—stainless steel for corrosive conditions, brass for electrical conductivity, or carbon steel for high-strength needs. Verify thread specifications (e.g., metric or imperial) and ensure compatibility with existing fasteners. Bulk purchasing often reduces costs, but confirm lead times and minimum order quantities. Request samples to test fit and performance before committing to large orders. Reputable suppliers should provide certifications for material quality and manufacturing standards.
