• Optimized for 0.025" maximum drilling thickness in sheet metal applications, providing reliable fastening in thin materials.
• Phillips pan head with No. 2 drive offers secure tool engagement and a low-profile finish for flush mounting.
• Fully threaded #6-18 shank ensures maximum grip length and consistent holding power across the entire fastener.
• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and suitability for global industrial supply chains.
• Standardized A/AB thread type delivers predictable performance and interchangeability in professional applications.

Professional Applications & Engineering Value

These black-oxide steel tapping screws solve critical challenges in sheet metal fabrication and assembly. The thread forming design eliminates the need for separate tapping operations, reducing labor costs and potential alignment issues. The Phillips pan head provides reliable drive transfer while maintaining a low profile that won't snag or interfere with adjacent components. Engineered for 0.025" maximum drilling thickness, these #6-18 thread fasteners deliver secure fastening in thin-gauge materials where strip-out is a common concern. The combination of fully threaded construction and pointed tip ensures quick starting and consistent penetration through sheet metal substrates, making them ideal for HVAC systems, electronic enclosures, and automotive panels where vibration resistance and corrosion protection are essential.

Specification Summary & Compliance

This #6-18 thread forming screw features precise 0.138" thread diameter with 18 threads per inch and 5/8" length following standard inch dimensions. The A/AB tapping screw type conforms to industry standards for thread forming applications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance and material safety. The black-oxide surface treatment provides consistent corrosion protection while maintaining dimensional accuracy for reliable performance in industrial fastening applications.
