S-93380A200 12-24 x 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with bronze-plated steel construction, extending service life in demanding industrial environments.
• Efficient thread cutting action with Type F design creates precise, strong threads in aluminum, brass, and sheet metal without pre-tapping.
• Enhanced drive stability from the Phillips No. 3 drive reduces cam-out risk for faster, more reliable installation.
• Flush, secure seating with the undercut flat head and 82° countersink angle prevents head protrusion and improves holding power.
• Optimized for coarse UNC threading ensuring rapid installation and high pull-out resistance in softer materials.
• Full threading and blunt tip design provides consistent grip along the entire length and aids in precise alignment during driving.
• Simplified installation process with compatibility for standard No. 8 drill bits (0.199"), reducing preparation time and tooling needs.

Professional Applications & Engineering Value

These 12-24 UNC thread cutting tapping screws are engineered to solve common fastening challenges in aluminum, brass, and sheet metal assemblies. The bronze-plated steel material offers a durable, corrosion-resistant finish ideal for HVAC, electronics enclosures, and automotive components where environmental exposure is a concern. The thread cutting (Type F) design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs. The undercut flat head with an 82° countersink angle ensures a flush fit that minimizes snagging and improves aerodynamic or aesthetic surfaces. Combined with a coarse thread spacing and Phillips drive, these screws deliver reliable, vibration-resistant connections that maintain integrity under dynamic loads, making them a cost-effective solution for high-volume manufacturing and maintenance repairs.

Specification Summary & Compliance

This product adheres to Unified Coarse (UNC) 12-24 thread standards with standard Class 2A tolerances for consistent fit. The flat head profile is undercut for optimal countersinking. Manufactured from steel with a bronze plating finish, these screws are compliant with industry standards for thread cutting tapping screws (Type F). They are designed for use with a No. 8 drill bit (0.199" diameter) and are suitable for general industrial applications. Complies with relevant material safety and environmental regulations, including RoHS and REACH directives, ensuring safe use in various global markets.
