S-90198A306 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel material, ideal for harsh industrial environments and outdoor applications.
• Effortless installation through thread forming design that creates strong, secure threads without pre-tapping in sheet metal up to 0.025" thickness.
• Optimal flush seating with flat undercut head and 82° countersink angle, preventing protrusion and ensuring smooth surface finishes.
• Enhanced driving efficiency with Phillips No. 2 drive, reducing cam-out and improving torque transfer during assembly.
• Full-length threading provides maximum grip and uniform load distribution across the entire 5/8" length in sheet metal applications.
• Regulatory compliance assurance with RoHS 3 and REACH standards, meeting strict environmental and safety requirements for industrial use.
• Precision-engineered dimensions including No. 10-12 thread pitch and pointed tip for accurate alignment and reduced installation time.

Professional Applications & Engineering Value

These 316 stainless steel tapping screws are specifically engineered for sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming design eliminates the need for separate tapping operations, reducing labor costs and preventing metal fatigue by creating strong, clean threads in materials up to 0.025" thickness. The flat undercut head with 82° countersink angle ensures flush mounting without surface protrusion, critical for aesthetic finishes and safety in assemblies. With Phillips No. 2 drive compatibility, these screws offer reliable installation in automated or manual processes, while the fully threaded No. 10-12 configuration provides superior pull-out resistance in demanding environments like HVAC systems, electronic enclosures, and automotive components.

Specification Summary & Compliance

These tapping screws feature precision No. 10-12 thread with right-hand direction and fully threaded 5/8" length, designed for use with No. 21 drill bit (0.159" diameter). The flat head profile incorporates an undercut design with 82° countersink angle for optimal seating. Manufactured to industry standards for thread forming screws (Type A/AB), these fasteners are RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental responsibility and regulatory adherence for industrial procurement.
