Professional Applications & Engineering Value
These M5 tapping screws are specifically engineered for plastic applications, where traditional fasteners may cause material stress or failure. The 18-8 stainless steel offers excellent durability and resistance to rust, making them ideal for electronics, automotive components, and outdoor equipment. The thread forming (TRS) technology with a 2.24mm pitch and blunt tip minimizes the risk of plastic cracking during installation, ensuring a tight, vibration-resistant hold without the need for additional inserts. Combined with the Phillips drive and pan head design, these screws streamline assembly processes, reducing labor costs and enhancing product longevity in demanding industrial settings.
Specification Summary & Compliance
This M5 x 18mm screw features a fully threaded shank with metric dimensions, including an 8.8mm head diameter and 3.32mm head height. It adheres to standard thread forming (TRS) specifications for plastic, with an approximate pitch of 2.24mm and compatibility with No. 21 drill bits. The product is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial applications.
