S-95893A232 Length 8 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring longevity in demanding industrial environments
• Enhanced torque transmission and reduced cam-out thanks to the T20 Torx drive design, providing reliable installation and removal
• Excellent holding power in plastic materials due to the TRS thread forming design, which creates strong, permanent threads without chips
• Secure, flush mounting with the standard 90° flat head profile, ideal for applications where a smooth surface finish is required
• Full-length threading for maximum grip across the entire 8mm length, distributing load evenly and preventing loosening
• Simplified installation process with pre-drilling guidance using a #30 drill bit (0.1285" diameter), ensuring precise fit in plastic substrates
• Compliance with major environmental regulations including RoHS 3 and REACH, making them suitable for global industrial supply chains

Professional Applications & Engineering Value

This M4 thread forming screw is specifically engineered to address common challenges in plastic assembly, where traditional fasteners can cause cracking or strip threads. The TRS thread forming design displaces material rather than cutting it, creating stronger threads with superior resistance to vibration loosening. Manufactured from 18-8 stainless steel, these screws maintain integrity in humid or corrosive environments common in automotive, electronics, and outdoor equipment applications. The T20 Torx drive provides significantly higher torque transmission compared to Phillips or slotted drives, reducing installation damage and improving production efficiency. With its fully threaded 8mm length and 1.79mm pitch, this fastener delivers optimal clamping force across the entire engagement area, making it ideal for securing plastic housings, components, and structural elements where reliability is critical.

Specification Summary & Compliance

This metric M4 x 8mm tapping screw features standard thread tolerances suitable for plastic applications, with a 1.79mm approximate thread pitch and blunt tip design for controlled thread forming. The fastener complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and material safety. The flat head with 90° countersink angle and 8.4mm head diameter provides proper seating in prepared holes, while the round shank cross-section maintains structural integrity during installation.
