S-93878A145 6-32 x 5/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Efficient installation in multiple materials including steel, aluminum, brass, and sheet metal without requiring pre-tapped holes
• Optimized thread-forming performance with SW tapping technology that creates strong, permanent threads while reducing material stress
• Reliable drive engagement through Phillips No. 2 drive design that minimizes cam-out and ensures consistent torque application
• Enhanced holding power with UNC coarse threading that provides superior pull-out resistance in softer materials
• Full-length threading maximizes thread engagement area for stronger, more secure fastening connections
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These 6-32 zinc-plated steel tapping screws deliver exceptional value in metal fabrication and assembly operations where thread-forming technology eliminates the need for costly tapping operations. The SW thread forming design creates precise, clean threads in steel, aluminum, brass, and sheet metal substrates without generating chips, making them ideal for automated assembly lines and high-volume production environments. The UNC coarse thread pattern combined with fully threaded construction ensures maximum engagement strength while the Phillips No. 2 drive provides reliable torque transmission for consistent installation. This combination of features addresses critical industrial pain points including reduced installation time, elimination of secondary tapping operations, and improved joint integrity in metal-to-metal fastening applications.

Specification Summary & Compliance

These precision-engineered tapping screws feature 6-32 UNC coarse thread with Class 2A tolerance standards, ensuring consistent fit and performance across production runs. The thread forming design conforms to SW tapping screw specifications with a recommended drill bit size #30 (0.1285") for optimal thread engagement. Manufacturing and material compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, providing assurance of responsible sourcing and production standards for industrial procurement requirements.
