Hex Socket Threaded Insert with Flange & Tapered Thread (M4–M10)

A high-quality screw-in insert featuring a hexagonal socket, integral flange and tapered external thread for reliable, precise connections. The hex socket allows easy installation with an Allen key, while the tapered external thread cuts cleanly into pre-drilled holes and provides a secure hold. The flange sits flush against the surface, distributing load evenly and adding stability to the connection. Made from durable zinc alloy, these inserts resist corrosion and wear, making them suitable for a wide range of applications.
