S-99461A936 Length 18 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding environments
• Efficient thread forming capability with TRS design creates strong, permanent threads in plastic materials without pre-tapping
• Optimized drive engagement through Phillips No. 1 drive system prevents cam-out and ensures secure installation
• Enhanced material displacement with blunt tip design minimizes stress cracking in plastic components during installation
• Complete thread coverage with fully threaded 18mm length provides maximum holding power throughout the engagement area
• Reliable regulatory compliance meeting RoHS 3 and REACH standards for environmentally conscious manufacturing operations
• Versatile pan head design offers low-profile fastening with excellent bearing surface for plastic assembly applications

Professional Applications & Engineering Value

These M2.5 thread forming screws are specifically engineered to address common challenges in plastic assembly applications, where traditional fastening methods often lead to material stress and cracking. The TRS (Thread Rolling Screw) design with 1.12 mm thread pitch creates precise, strong threads through material displacement rather than cutting, resulting in superior pull-out resistance and reduced installation torque. Manufactured from 18-8 stainless steel, these fasteners maintain structural integrity in corrosive environments while the pan head with Phillips No. 1 drive provides reliable installation without specialized tools. The fully threaded blunt tip configuration ensures smooth material penetration while minimizing the risk of plastic fracture, making these screws ideal for electronics enclosures, automotive plastic components, and consumer product assemblies where material integrity is critical.

Specification Summary & Compliance

This metric tapping screw features M2.5 diameter with 18mm length and fully threaded configuration using standard thread forming methodology. The screw maintains precise dimensional accuracy with 1.12 mm thread pitch and Phillips No. 1 drive compatibility. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and chemical safety in industrial applications. The 18-8 stainless steel composition provides consistent performance while the design follows industry-standard thread forming principles for plastic materials.
