S-93878A131 10-32 x 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in harsh industrial environments
• Excellent thread-forming capability creates secure, permanent threads in materials like steel, aluminum, and brass without pre-tapping
• Vibration-resistant performance through UNF fine thread spacing, maintaining tight connections in high-stress applications
• Easy installation and removal with standard slotted pan head design compatible with common hand tools
• Full threading for maximum grip ensures consistent holding power along the entire 3/8" length
• Broad material compatibility works effectively with steel, aluminum, brass, cast iron, and sheet metal substrates
• Precision dimensional accuracy with No. 10 screw size and 0.19" thread diameter for reliable fit and performance

Professional Applications & Engineering Value

These 10-32 UNF thread forming screws deliver exceptional engineering value by solving common fastening challenges in metalworking and assembly operations. The zinc-plated steel construction provides essential corrosion protection while the thread forming design (SW type) eliminates the need for separate tapping operations, reducing installation time and labor costs. The combination of fine UNF threading and fully threaded shank creates superior resistance to vibration loosening in automotive, machinery, and electronic enclosures. The slotted pan head offers reliable tool engagement for consistent torque application, while the blunt tip prevents damage to pre-drilled materials. These tapping screws are engineered specifically for demanding applications in steel, aluminum, brass, cast iron, and sheet metal, providing secure fastening without the risk of strip-out or cross-threading common in traditional machine screws.
