Product Description

<p>The OSG Oversized Spiral-Point Tap #4-40 UNC H7 2-Flute Plug Chamfer High-Speed Steel (MPN 2003100) is a precision threading tool designed for through-hole applications. Its spiral-point geometry pushes chips forward, reducing clogging and improving thread quality. The oversized design (H7 tolerance) compensates for thread shrinkage after coating or heat treatment, ensuring accurate final thread fit.</p><p>This tap features a 2-flute plug chamfer, ideal for general-purpose tapping in a wide range of materials. Manufactured from high-speed steel for durability and performance. 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 H7 tolerance and oversized design mean for this tap?

The H7 tolerance indicates the tap is manufactured to produce threads with an H7 fit class, which is a common tolerance for general-purpose threading. The oversized design means the tap is slightly larger than standard to allow for thread shrinkage after subsequent processes like coating or heat treatment, ensuring the final thread meets specifications.

Can I get a quote in SGD and how is GST handled for Singapore buyers?

Yes, 3G Electric provides quotes in SGD upon request. For buyers in Singapore, GST is handled accordingly. We also offer fast delivery across Singapore and Southeast Asia.
