Product Description

<p>This OSG oversized thread-forming tap is engineered for precision threading in demanding applications. With a 1/2&quot;-20 UNF thread size and H11 oversize tolerance, it compensates for hole shrinkage after heat treatment or coating. The plug chamfer design facilitates smooth entry, while the cobalt HSS construction ensures durability and heat resistance for extended tool life.</p><p>Ideal for automotive, aerospace, and general manufacturing, this tap is a reliable choice for producing accurate threads in tough materials. As a Singapore-based supplier, 3G Electric offers SGD quotes on request, handles GST for local buyers, and provides fast delivery across Singapore and Southeast Asia.</p>

Frequently Asked Questions

What does the H11 oversize designation mean for this tap?

The H11 oversize indicates that the tap's thread pitch diameter is larger than standard, allowing for thread growth after coating or heat treatment. This ensures final threads meet tolerance requirements.

Can I get a quote in SGD and what are the delivery options?

Yes, we provide SGD quotes on request. For Singapore buyers, GST is handled. We offer fast delivery across Singapore and Southeast Asia.
