S-99461A916 Length 8 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 industrial environments.
• Excellent holding power in plastic materials due to thread forming (TRS) design, which creates strong, vibration-resistant threads without pre-tapping.
• Efficient installation with Phillips No. 1 drive, providing secure tool engagement and reducing cam-out risks during assembly.
• Consistent performance with fully threaded blunt tip, allowing for uniform stress distribution and preventing material cracking in plastic applications.
• Wide compatibility with standard No. 52 drill bits (0.0635" diameter), simplifying hole preparation and reducing assembly time.
• Compliance with RoHS 3 and REACH regulations, ensuring safe use in electronic, automotive, and consumer goods without hazardous substances.
• Optimized 0.89mm thread pitch and M2 x 8mm size, delivering precise fastening for small-scale plastic components in compact designs.

Professional Applications & Engineering Value

This M2 TRS tapping screw is engineered to address common challenges in plastic assembly, such as strip-out and weak thread engagement. The thread forming technology displaces material to create permanent, high-strength threads without chips, ideal for thermoplastics and soft plastics where traditional screws may fail. Made from 18-8 stainless steel, it resists oxidation and chemical exposure, extending service life in electronics enclosures, automotive trim, and consumer appliances. The pan head with Phillips drive ensures flush mounting and easy installation, while the fully threaded blunt tip minimizes stress concentration, reducing the risk of plastic fracture. This design is critical for B2B applications requiring reliable, repeatable fastening in automated production lines.

Specification Summary & Compliance

This screw adheres to metric standards with M2 diameter, 8mm length, and 0.89mm thread pitch, ensuring precise fit in pre-drilled holes (recommended No. 52 drill bit). The thread forming (TRS) type and right-hand threading provide consistent performance per industry norms. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances for use in global markets.
