S-90315A481 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh industrial environments.
• Excellent holding power through thread forming technology that creates strong, permanent threads in sheet metal without pre-tapping.
• Streamlined installation with Phillips drive and oval head design providing a flush finish and reduced driver cam-out.
• Optimized for sheet metal applications with fully threaded shank and 15 TPI for maximum grip in thin materials up to 0.025" thickness.
• Precise countersinking with 82° head angle ensuring smooth, flush mounting in prepared holes.
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, sustainable industrial use.
• Right-hand threading for standard installation procedures and compatibility with common power tools.

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The thread forming Type A/AB design eliminates the need for separate tapping operations, significantly reducing installation time and labor costs while creating stronger, more reliable connections. The fully threaded configuration ensures maximum engagement throughout the material thickness, preventing loosening under vibration and thermal cycling. With Phillips drive compatibility and oval head profile, these screws provide both aesthetic appeal and practical installation benefits, making them ideal for HVAC systems, electronic enclosures, automotive components, and industrial machinery where corrosion resistance and structural integrity are paramount.
