S-95893A241 Length 30 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in humid or demanding environments.
• Enhanced torque transmission and strip-resistance from the T20 Torx drive, allowing for higher tightening forces and reduced tool slippage.
• Reliable thread forming in plastics with TRS type and blunt tip design, minimizing stress cracking and providing secure, vibration-resistant assemblies.
• Streamlined installation with a 90° flat head and standard profile, enabling flush mounting and a clean finish in plastic components.
• Full 30mm threading ensures maximum grip length and uniform load distribution across the entire engagement area.
• Precision compatibility with a No. 30 drill bit (0.1285"), facilitating accurate pilot holes for optimal thread formation.
• Compliance with environmental regulations including RoHS 3 and REACH, making them suitable for global supply chains and sensitive applications.

Professional Applications & Engineering Value

These M4 x 30mm TRS Torx flat head tapping screws are specifically engineered for plastic assembly, where traditional fasteners may cause material failure. The 18-8 stainless steel offers excellent corrosion resistance, crucial for outdoor or high-moisture applications like automotive trim, electronic enclosures, and consumer products. The thread forming design displaces plastic material without cutting, creating strong, strip-resistant threads that withstand vibration and thermal cycling. With a T20 Torx drive, installers achieve higher torque application with minimal cam-out, reducing assembly time and improving joint integrity. The fully threaded metric shank and 1.79mm pitch ensure consistent engagement, making these screws ideal for high-volume manufacturing where reliability and efficiency are paramount.

Specification Summary & Compliance

This M4 x 30mm screw features a right-hand thread with an approximate 1.79mm pitch and fully threaded round shank. The flat head has a standard profile with an 8.4mm diameter, 2.9mm height, and 90° countersink angle for seamless integration. Manufactured to precise metric dimensions, it is designed for use with a No. 30 drill bit (0.1285"). The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for environmentally conscious industries.
