S-95115A155 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding environments
• Maximum torque transmission through the drilled spanner drive design, preventing tool slippage during installation
• Complete thread engagement with fully threaded design ensures superior holding power in sheet metal applications
• Precision installation with 82° countersink angle and compatibility with 3/16" drill bits for clean, flush finishes
• Reliable thread forming capability creates strong, permanent threads in materials up to 0.025" thickness
• Industry compliance assurance with RoHS 3 and REACH regulations for safe, environmentally responsible manufacturing
• Optimized thread design with 11 threads per inch provides excellent pull-out resistance in thin materials

Professional Applications & Engineering Value

These No. 12 flat head tapping screws are engineered specifically for sheet metal applications where reliability and precision are paramount. The 18-8 stainless steel composition delivers exceptional corrosion resistance, making these thread forming screws ideal for outdoor equipment, electrical enclosures, and HVAC systems exposed to moisture and harsh conditions. The fully threaded design ensures maximum contact surface area, preventing loosening from vibration while the drilled spanner drive accommodates high-torque installation without stripping. With their A/AB screw type classification and 82° countersink angle, these fasteners provide flush mounting in thin gauge materials up to 0.025" thickness, solving common challenges of material deformation and insufficient thread engagement in sheet metal fabrication projects.

Specification Summary & Compliance

These tapping screws feature precise dimensional specifications including a 0.216" thread diameter with 11 threads per inch, 1-1/4" length, and standard flat head profile. Manufactured to thread forming standards with right-hand thread direction and pointed tip for easy starting. The products are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. The drilled spanner drive (No. 12 size) and standard countersink angle meet industrial fastener requirements for reliable performance in professional applications.
