• Secure and efficient installation with an external hex drive and flanged design, providing excellent torque transfer and preventing over-insertion.
• Reliable coarse UNC threading ensures quick, strong fastening in a variety of materials, reducing the risk of cross-threading.
• Full threading and blunt tip design allows for maximum thread engagement and controlled penetration, improving joint integrity.
• Compliance with ASME B18.6.3 specifications guarantees consistent quality, dimensional accuracy, and interchangeability for industrial applications.
• RoHS 3 compliance ensures environmental safety and meets global regulatory standards for hazardous substances.

Professional Applications & Engineering Value

This 6-32 UNC thread cutting tapping screw is engineered to address common challenges in metal assembly, such as stripping threads and inconsistent clamping force. Its Type F thread cutting design and coarse thread spacing enable it to form precise, durable threads directly in materials like aluminum, brass, cast iron, and sheet metal, eliminating the need for separate tapping operations. The zinc-plated steel material offers excellent resistance to rust and corrosion, while the external hex drive and flanged feature provide superior grip and distribute load evenly, preventing surface damage. Ideal for industrial machinery, automotive components, and electrical enclosures, this screw ensures reliable, vibration-resistant fastening in high-stress environments, enhancing overall assembly durability and reducing maintenance needs.

Specification Summary & Compliance

This screw adheres to UNC thread standards with a 6-32 thread size, coarse spacing, and fully threaded shank for consistent performance. It meets ASME B18.6.3 specifications (referencing SAE J933) for dimensional accuracy, including a 1/4" length, 1/4" head width, and 0.328" flange diameter. Compliant with RoHS 3 (2015/863/EU), it is free from hazardous substances, ensuring safety and environmental responsibility in industrial applications.
