Brass Threaded Inserts.

What are Brass Threaded Inserts?

Brass threaded inserts, sometimes referred to as heat press inserts or 3D print threaded inserts, are small cylindrical components featuring an internal thread. They are designed to be embedded within softer materials such as thermoplastics. Once installed, they provide a strong, permanent thread connection that allows precision screws to be fastened without damaging the parent material.

These brass inserts for plastic include external ridges and knurls, ensuring the insert remains locked in place when melted or pressed into the material. By distributing fastening loads across a metal surface rather than direct plastic threads, they help minimise the risk of stripped threads or damaged components.

How Threaded Brass Inserts Work

Thread inserts for plastic are often used in applications where a durable threaded connection is required, but the base material may not withstand repeated fastener installation. Industries such as consumer electronics, automotive components, or even bespoke prototype devices rely on brass inserts for 3D-printed parts because of their improved load-bearing capability.

Many 3D printing enthusiasts install 3D print threaded inserts during assembly or post-processing to enhance part strength. By applying controlled heat (commonly with a dedicated heat press), the brass heat-set inserts for plastic liquify the surrounding thermoplastic and embed themselves securely.

Once installed and cooled, the heat press threaded inserts create a solid anchor point for additional threaded components. This method is particularly popular for 3D printing threaded inserts since it reduces the risk of threads stripping in delicate prototypes.

Materials Brass Threaded Inserts Are Made From

Accu’s brass inserts are manufactured from high-quality brass. This material offers excellent corrosion resistance, thermal conductivity and mechanical strength. Brass also conducts heat efficiently, helping it bond more smoothly with thermoplastic during heat press installation.

When working with thermoset plastics, consider using our self-tapping threaded screw inserts which are best suited for materials which cannot melt and need to be pre-drilled.

Size And Type Brass Threaded Inserts Available

Our range of threaded brass inserts is offered in a wide range of metric sizes, to suit threads from M3 up to M6. Their depth spans from 4.7mm to 12.7mm. For installation, the recommended hole size ranges between 4mm and 10.6mm, ensuring a precise fit.The combination of diameter and depth options lets you match the insert to your specific application requirements.

Accu's selection also spans a variety of installation methods, from traditional heat set inserts, to ultrasonic, push fit and even expansion fit inserts, covering almost any variability to adding threads to your project.

By selecting the right threaded inserts for 3D-printed parts, you can boost the durability of everything from prototypes to production assemblies.

FAQs

Q: What are brass inserts used for?

A: Brass thread inserts for plastic are used to facilitate robust metal threads in thermoplastic parts. Commonly referred to as threaded inserts for 3d printed parts, these inserts help prevent plastic threads from stripping. Brass inserts for 3d printed parts are popular in product development and electronics assemblies where reliable, repeatable assembly and disassembly are needed.

Q: How do you install brass threaded inserts?

A: Installing brass threaded inserts involves applying heat, usually with a specialised press to melt the surrounding plastic. Once softened, the insert is pressed in place and allowed to cool, creating a secure hold. This method is especially effective for threaded inserts for 3d printed parts, where using 3d print brass inserts adds extra durability.

Q: What size hole for brass inserts?

A: The recommended hole size for brass inserts depends on the size of the insert itself. When installing threaded inserts for 3d printed parts, it is crucial to match the pilot hole precisely to avoid stress on the plastic. Refer to our 3d print brass insert hole size chart to find the correct hole diameter so that your brass inserts for 3d printed parts fit snugly.
