S-95015A298 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced tamper resistance with T20 Torx drive that deters unauthorized removal in high-security environments
• Superior corrosion resistance from 18-8 stainless steel construction for long-lasting performance in harsh conditions
• Optimized thread forming design (AB Type) creates stronger, more reliable threads in sheet metal without pre-tapping
• Precise 82° countersink angle ensures flush mounting and professional finish in sheet metal assemblies
• Full threading along entire 1/2" length provides maximum grip and load distribution in thin materials
• Consistent dimensional accuracy with tight head diameter tolerance (±0.005") for reliable installation
• Right-hand threading with pointed tip enables quick starting and smooth driving into pre-drilled holes

Professional Applications & Engineering Value

This No. 8-15 T20 tamper-resistant Torx flat head tapping screw delivers exceptional engineering value for sheet metal applications where security and durability are paramount. The 18-8 stainless steel composition provides excellent corrosion resistance, making it ideal for outdoor equipment, electrical enclosures, and industrial machinery exposed to moisture or chemicals. The thread forming technology (AB Type) creates stronger, more vibration-resistant connections by displacing material rather than removing it, eliminating chip-related issues in sheet metal assemblies. Combined with the tamper-resistant Torx drive, this fastener prevents unauthorized access while the 82° countersink angle ensures clean, flush installations. The fully threaded design maximizes engagement in materials up to 0.025" thickness, providing reliable performance in demanding industrial environments where security and longevity are critical requirements.
