S-95893A413 Length 4 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in various industrial environments.
• Enhanced torque transmission and reduced cam-out thanks to the T5 Torx drive, providing secure installation and minimizing tool slippage.
• Optimal flush mounting with a standard flat head profile and 90° countersink angle, ideal for smooth surface finishes in plastic assemblies.
• High-strength thread forming using TRS technology, creating durable threads in plastic materials without pre-tapping for superior pull-out resistance.
• Precision compatibility with a 1.2mm drill bit, simplifying installation and reducing assembly time in plastic components.
• Full threading and blunt tip design for consistent grip along the entire 4mm length, preventing material splitting and ensuring uniform clamping force.
• Compliance with stringent regulations including RoHS 3 and REACH, guaranteeing safe use in industrial and consumer applications.

Professional Applications & Engineering Value

This M1.6 x 4mm zinc-plated steel tapping screw is engineered to address common fastening challenges in plastic applications, such as material cracking and weak thread retention. The TRS thread forming design displaces plastic material during installation, creating strong, permanent threads that resist vibration and loosening. Combined with a T5 Torx drive, it ensures high torque transfer without stripping the drive, making it ideal for automated assembly lines and precision electronics. The flat head sits flush to avoid protrusions, while the fully threaded shank and 0.67mm pitch provide maximum holding power in brittle or soft plastics, reducing the need for additional inserts and lowering overall production costs.

Specification Summary & Compliance

This metric screw features an M1.6 size with a 4mm length, fully threaded right-hand design, and an approximate thread pitch of 0.67mm for precise engagement. It adheres to standard thread forming tolerances and is compatible with a 1.2mm drill bit diameter. The product conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
