S-90925A266 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Maximum torque transmission and reduced cam-out with T10 Torx drive design for secure, efficient installation
• Strong, permanent threads without chips through thread forming technology that displaces material rather than cutting it
• Easy starting and alignment with fully threaded pointed tip design for quick penetration into sheet metal
• Optimized for sheet metal applications with No. 4-24 thread specification and compatibility with No. 44 drill bits
• Secure fastening with rounded pan head providing a low-profile finish and excellent bearing surface
• Compliance with international environmental standards including RoHS 3 and REACH for global manufacturing applications

Professional Applications & Engineering Value

These No. 4-24 x 3/4" zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliable, permanent fastening is critical. The thread forming design eliminates the problem of metal chips contaminating sensitive equipment while creating stronger threads than traditional cutting screws. The T10 Torx drive system provides superior torque transmission compared to Phillips or slotted drives, reducing installation time and preventing tool slippage that can damage fastener heads. The fully threaded pointed tip ensures easy starting and consistent engagement throughout the material thickness, making them ideal for assembly lines in HVAC, electronics enclosures, and automotive components where speed and reliability are paramount.

Specification Summary & Compliance

These tapping screws feature precision No. 4-24 UNC Class 2A threads with right-hand direction and 24 threads per inch for optimal engagement in sheet metal. The 3/4" length and 0.112" thread diameter are designed for maximum holding power in materials up to 0.025" thickness when used with recommended No. 44 drill bits. Manufactured to industry standards for thread forming screws (Type A/AB), these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for safe use in global industrial applications.
