S-95015A313 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced Security & Tamper Resistance with specialized Torx T25 drive requiring matching tools, preventing unauthorized access in sensitive applications
• Superior Corrosion Resistance through 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments
• Optimized Thread Forming Design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and improving pull-out resistance
• Precision Flat Head Profile with 82° countersink angle provides flush mounting and clean aesthetic finish in metal assemblies
• Full Threading & Pointed Tip enables quick starting and smooth penetration through materials up to 0.025" thickness
• Consistent Performance maintained through tight head diameter tolerance (±0.005") ensuring reliable seating and uniform appearance
• Simplified Installation with compatibility to standard No. 21 drill bits (0.159" diameter), reducing tooling requirements and setup time

Professional Applications & Engineering Value

These 18-8 stainless steel tamper-resistant Torx flat head tapping screws deliver exceptional value in sheet metal applications where security, corrosion resistance, and installation efficiency are critical. The thread forming design (AB type) eliminates the need for separate tapping operations by displacing material to create strong, load-bearing threads that resist vibration loosening. The right-hand threading with 12 threads per inch provides optimal engagement in thin gauge materials up to 0.025" thickness, while the fully threaded No. 10-12 configuration ensures maximum holding power across the entire fastener length. The combination of stainless steel material and tamper-resistant Torx drive makes these screws ideal for outdoor enclosures, electrical cabinets, HVAC systems, and security fixtures where environmental exposure and unauthorized access are concerns.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread tolerance and head diameter tolerance of -0.005" to +0.005". These thread forming screws comply with industry standards for AB type tapping screws and feature 82° countersink angle for proper seating in standard chamfered holes. The 18-8 stainless steel composition provides inherent corrosion resistance and meets material specifications for industrial fasteners. Compatible with No. 21 drill bits (0.159" diameter) for proper hole preparation. Manufactured in compliance with RoHS and REACH environmental directives.
