Unifix Countersunk Self Tapping Screws - Bag of 50 - 4.0 x 25mm

Unifix Countersunk Self Tapping Screws are designed to cut their own thread into pre drilled surfaces such as sheet metal or plastic, providing strong grip without needing access to the opposite side. Ideal for situations where only one side is reachable, they are commonly used to securely attach components to surfaces. The countersunk head ensures a flush, neat finish.
