Hilitchi Brass Knurled Threaded Insert Assortment Kit, 460 Count

• ✓460 brass knurled threaded inserts
• ✓Durable brass, corrosion resistant
• ✓Smooth burr-free finish
• ✓Deep clean threads resist stripping

This Hilitchi assortment kit gives you 460 brass knurled threaded inserts for embedding into plastic and printed parts. The brass body holds its shape under load and resists abrasion and corrosion, while the knurled outer surface grips the material around it for a firm, lasting hold.

Each insert has a smooth, burr-free finish and deep, neat threads that stay stable as you turn a screw and are not easy to strip. The set suits makers, repairers and anyone working with injection moulding, circuit boards, electronics or 3D printed parts, and covers a range of sizes so you can match the job at hand.

Benefits

• ✓Adds strong, reusable metal threads to plastic parts
• ✓Brass construction resists deformation, abrasion and corrosion
• ✓Smooth circular shape with no burrs for easy installation
• ✓Deep, tidy threads that hold firm without stripping
• ✓Works with ultrasonic, heat or mould-in installation methods
• ✓Neatly organised assortment covering many sizes

How to Use

Set the inserts with ultrasonic or heat into a tapered hole, or mould them in during injection so the plastic forms around the brass. You can also use a normal soldering iron to press them into 3D printed holes.

Tip: When setting inserts by heat, put something in the threads first to stop melted plastic from running into the centre.
