• Precise compatibility with No. 29 drill bit (0.136" diameter), ensuring accurate hole sizing for reliable performance in plastic assemblies.
• Full threading along the 5/8" length delivers maximum grip and uniform load distribution in plastic applications.
• Environmental compliance with RoHS 3 and REACH standards, making them safe for use in regulated industries and global markets.

Professional Applications & Engineering Value

These No. 8 x 5/8" 18-8 Stainless Steel Phillips Pan Head Tapping Screws are specifically engineered for plastic fastening applications where material integrity and assembly efficiency are critical. The thread forming (DST) technology displaces plastic material to create strong, load-bearing threads without generating chips, eliminating cleanup and reducing the risk of loose debris in sensitive components. The rounded pan head and Phillips drive provide a low-profile, secure fastening solution that resists vibration loosening, while the blunt tip design prevents piercing through thin plastic walls. Ideal for electronics enclosures, automotive trim, and consumer products, these screws ensure durable, corrosion-resistant joints that maintain performance in demanding conditions, supported by 18-8 stainless steel for lasting strength.
