S-95015A274 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced Security: Tamper-resistant Torx T20 drive prevents unauthorized removal, ideal for public or high-security industrial applications.
• Superior Corrosion Resistance: Made from 18-8 Stainless Steel for excellent durability in harsh environments, reducing maintenance and replacement costs.
• Optimized for Sheet Metal: Thread forming (Type AB) design creates strong, permanent threads in sheet metal up to 0.025" thick without pre-tapping, speeding up assembly.
• Secure Flush Finish: Standard flat head with an 82° countersink angle sits flush with the material surface for a smooth, professional appearance and safety.
• Full Thread Engagement: Fully threaded shank provides maximum grip and holding power across the entire 1-1/2" length for a more reliable fastening.
• Precision Fit: Consistent No. 8-15 thread and pointed tip ensure easy starting and straight driving, minimizing installation errors and material damage.
• Regulatory Compliance: Meets RoHS 3 and REACH standards, ensuring the fastener is safe for use in regulated industries and global markets.

Professional Applications & Engineering Value

This 18-8 Stainless Steel tapping screw is engineered to solve common challenges in sheet metal assembly. Its thread forming (Type AB) design displaces material to create strong, strip-resistant threads without generating chips, which is critical for electrical enclosures, HVAC systems, and machinery panels where debris contamination must be avoided. The Tamper-Resistant Torx T20 drive offers higher torque transmission compared to standard drives, reducing cam-out and tool wear while providing vital security against vandalism. The combination of a fully threaded body and pointed tip ensures quick alignment and deep penetration, significantly speeding up production lines. The flat head with an 82° countersink provides a clean, flush finish that enhances product aesthetics and prevents snagging, making it a reliable choice for both functional and visible applications in industrial settings.

Specification Summary & Compliance

This fastener adheres to standard inch system measurements with a No. 8-15 thread (0.164" diameter, 15 TPI) and a length of 1-1/2". The head diameter tolerance is specified from -0.016" to 0.032" for a precise fit. It is manufactured as a Type AB thread forming tapping screw for use in materials like sheet metal, with a recommended drill bit size of No. 29 (0.136" diameter). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for demanding industrial and commercial applications.
