S-90925A148 Length 1/2" 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 T15 Torx drive for secure fastening and improved installation efficiency
• Strong, permanent threads in sheet metal created by thread forming design that displaces material without cutting, providing excellent vibration resistance
• Optimal grip and load distribution from the rounded pan head design that sits flush against surfaces
• Full 1/2" threading coverage ensures maximum holding power across the entire fastener length
• Precision compatibility with No. 32 drill bits (0.116" diameter) for clean, accurate installations in sheet metal up to 0.025" thickness
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

These No. 6 zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliable fastening is critical. The thread forming design eliminates the need for pre-tapped holes while creating durable, vibration-resistant connections that maintain integrity under stress. The T15 Torx drive system prevents tool slippage during high-torque installation, reducing installation time and preventing damage to fastener heads. With their fully threaded 1/2" length and 18 threads per inch configuration, these screws provide maximum engagement in thin materials commonly used in HVAC systems, electronic enclosures, automotive components, and industrial machinery where sheet metal joining is required.

Specification Summary & Compliance

These tapping screws feature a No. 6 screw size with 0.138" thread diameter and 18 threads per inch in right-hand thread direction. The fasteners are manufactured to precise dimensional standards with Class 2A thread tolerances for consistent performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures they meet current environmental and safety standards for industrial use worldwide. The thread forming (Type A/AB) design follows established industry standards for sheet metal fastening applications.
