Precision BA threading meets reliability in the OSG BA Spiral Point Threading Tap. Built for through-hole tapping on miniature components, it combines cobalt-enhanced HSS with a steam oxide coating for durable, repeatable threads.

• Thread size: 8BA through-hole threading (British Association standard) for fine-pitch, miniature assemblies.
• Material: HSS‑E (high-speed steel with cobalt) for superior hardness and heat resistance during demanding tapping.
• Coating: Steam oxide coating reduces friction and enhances corrosion resistance for longer tool life.
• Design: Spiral Point geometry facilitates efficient chip evacuation and smooth entry in through-holes.
• Application: Ideal for precision BA threads in electronics enclosures, control panels, and small mechanical assemblies.
• Brand: OSG threading solutions—trusted for durable, accurate threads in challenging materials.
• Compatibility: Designed to work with standard tapping setups and tools like tap wrenches or machine collets.

With this OSG BA Spiral Point Threading Tap, you’ll achieve clean, accurate 8BA threads consistently. The cobalt-enhanced steel and steam oxide coating deliver higher wear resistance and smoother operation, reducing downtime and rework. The spiral-point geometry ensures reliable chip evacuation in through-holes, making it well-suited for precision electronics housings, instrumentation, and compact assemblies where dependable thread quality matters. For optimal results, pair with proper lubrication and a stable tapping setup.
