S-94195A340 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated self-drilling tip that penetrates up to 0.21" thickness in steel and sheet metal
• Superior corrosion resistance provided by 410 stainless steel construction for long-lasting performance in demanding environments
• Optimized installation efficiency through Phillips No. 3 drive design that prevents cam-out during high-torque applications
• Enhanced thread engagement with fully threaded 1/4"-14 BSD thread forming design that creates strong, permanent fastening points
• Flush surface finishing enabled by standard flat head profile with 82° countersink angle for smooth, professional installations
• Reliable regulatory compliance meeting RoHS 3 and REACH standards for safe use across industrial applications
• Versatile material compatibility specifically engineered for steel, stainless steel, and sheet metal applications

Professional Applications & Engineering Value

These 1/4"-14 tapping screws deliver exceptional engineering value by solving critical installation challenges in metal fabrication. The 410 stainless steel construction provides excellent strength and corrosion resistance, while the self-drilling tip (No. 3 drill type with 5/16" length) eliminates the time-consuming pre-drilling process, significantly reducing labor costs and assembly time. The thread forming BSD design creates strong, strip-resistant threads in parent material without generating chips, making them ideal for sheet metal applications where debris contamination must be avoided. The Phillips flat head configuration ensures secure installation and flush finishing, while the fully threaded 1-1/2" length provides maximum grip across the entire fastening surface. These features combine to create reliable, vibration-resistant connections in HVAC systems, electrical enclosures, and structural metal assemblies.

Specification Summary & Compliance

These industrial fasteners feature precise 1/4"-14 thread specifications with right-hand threading and standard Class 2A tolerances. The BSD tapping screw type follows established thread forming standards for metal applications. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material transparency. Critical dimensions include 0.477" head diameter, 0.153" head height, and standard 82° countersink angle for proper seating in prepared or unprepared materials.
