S-92115A211 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black zinc-plated steel coating for extended service life in industrial environments
• Excellent thread-forming capability creates permanent, vibration-resistant threads in sheet metal without pre-tapping
• Optimized drive efficiency with Phillips No. 1 drive for secure installation and reduced cam-out risk
• Maximum material engagement through fully threaded design ensures consistent holding power along entire fastener length
• Precision dimensional control with Class 2A thread tolerances for reliable fit and consistent performance
• Enhanced installation safety with blunt tip design that minimizes damage to materials and reduces injury risk
• Regulatory compliance assurance meeting RoHS 3 standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These thread forming Type B tapping screws are engineered specifically for sheet metal applications where traditional fastening methods fall short. The black zinc-plated steel construction provides exceptional corrosion protection in demanding industrial settings, while the Phillips pan head design offers a low-profile installation with excellent drive transfer. The thread forming technology eliminates the need for pre-tapped holes, creating strong, permanent threads that resist vibration loosening and maintain clamping force over time. With a No. 4-24 thread pitch and 1/4" length, these screws deliver optimal performance in thin-gauge metal assemblies, electrical enclosures, and HVAC systems where reliable fastening is critical to structural integrity.

Specification Summary & Compliance

This No. 4-24 x 1/4" tapping screw features Class 2A thread tolerances with right-hand threading and full thread engagement. Manufactured to industry standards for thread forming Type B screws, it requires a No. 44 drill bit (0.086" diameter) for proper installation in sheet metal applications. The product is fully RoHS 3 (2015/863/EU) Compliant, ensuring environmental regulatory adherence while maintaining the mechanical properties necessary for industrial durability and performance consistency.
