S-99397A614 Length 5 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission and anti-camout protection with Torx Plus IP10 drive, reducing tool slippage and assembly errors.
• Reliable thread forming in plastic materials using tri-lobe shank design, ensuring secure fastening without pre-tapping.
• Enhanced corrosion resistance from zinc-plated steel construction, extending service life in industrial environments.
• Consistent full threading and 1.27mm pitch for uniform load distribution and reduced stress concentrations.
• Broad compliance with environmental standards including RoHS 3 and REACH, meeting global regulatory requirements.
• Optimized pan head design with 5.6mm diameter and 2.4mm height, providing a low-profile, flush finish in plastic assemblies.
• Precision M3.12 size and 5mm length for accurate fit in designated drill sizes, minimizing installation time and rework.

Professional Applications & Engineering Value

These M3.12 thread forming screws are engineered to address common challenges in plastic fastening applications, such as material cracking and stripped threads. The tri-lobe shank cross-section displaces plastic material during installation, creating strong, permanent threads that resist vibration loosening. Made from zinc-plated steel, they offer durability against moisture and chemicals, while the Torx Plus IP10 drive ensures high torque transfer with minimal wear on tools. Ideal for electronics enclosures, automotive components, and consumer goods, these TRS tapping screws enhance assembly speed and reliability, reducing production downtime and warranty claims in industrial screw applications.

Specification Summary & Compliance

This product features metric M3.12 size with 5mm length, fully threaded with 1.27mm approximate pitch and blunt tip for thread forming (TRS type) in plastics. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety. The screw utilizes a standard pan head with Torx Plus IP10 (T10) drive, designed for use with No. 37 drill bit (0.104" diameter), and is manufactured to precise dimensional tolerances suitable for plastic assembly applications.
