S-91675A315 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 410 stainless steel construction for long-lasting performance in demanding industrial environments
• Superior holding power through thread forming technology that creates stronger, more reliable connections in sheet metal applications
• Enhanced installation efficiency with external hex drive design allowing for high-torque application and quick assembly
• Increased load distribution thanks to the integrated flange design that prevents pull-through and reduces surface damage
• Full thread engagement along the entire 5/8" length ensures maximum grip strength and vibration resistance
• Precision compatibility with No. 32 drill bits (0.116" diameter) for optimal hole preparation and thread formation
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

Engineered specifically for sheet metal applications, these No. 6-18 TPI tapping screws deliver exceptional performance in HVAC systems, electronic enclosures, and automotive assemblies. The thread forming design eliminates the need for pre-tapped holes while creating stronger, more reliable connections that resist loosening under vibration. Made from 410 stainless steel, these flanged hex head screws provide excellent corrosion resistance in harsh environments, while the external hex drive allows for high-torque installation without cam-out issues. The fully threaded 5/8" length ensures maximum engagement depth, making them ideal for joining multiple layers of sheet metal up to 0.025" thickness with superior pull-out resistance.

Specification Summary & Compliance
