• 7mm pan head with standard profile offers excellent bearing surface and clean aesthetic finish for plastic assemblies
• Fully threaded 12mm length with 1.79mm pitch delivers maximum holding power across the entire fastener engagement
• Environmental compliance assurance meets RoHS 3 and REACH standards for use in regulated industries and sensitive applications
• Precision M4 metric sizing ensures consistent performance and interchangeability in global manufacturing operations

Professional Applications & Engineering Value

These M4 thread forming screws are specifically engineered for plastic assembly applications where traditional fastening methods often fail. The 18-8 stainless steel construction provides exceptional corrosion resistance while the TRS thread forming design displaces plastic material to create strong, vibration-resistant threads without creating debris that could compromise electronic components. The Phillips drive system with No. 1 size ensures reliable installation in automated assembly processes, while the pan head design distributes clamping force evenly across plastic surfaces. These tapping screws are ideal for automotive trim, electronic enclosures, consumer products, and industrial equipment where plastic fastening demands both mechanical performance and aesthetic considerations.

Specification Summary & Compliance

These metric thread forming screws feature M4 diameter with 12mm length and 1.79mm pitch, manufactured to precise dimensional standards for consistent performance. The TRS tapping screw type utilizes thread forming technology for plastic applications, requiring No. 30 drill bit (0.1285" diameter) for proper installation. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial use across global markets.
