Frequently Asked Questions

What is the OSG #12-28 UNF thread forming tap used for?

This OSG thread forming tap is used to create internal threads in ductile materials like aluminum, brass, and low-carbon steel without cutting chips. It is ideal for high-speed production in automotive, aerospace, and general manufacturing applications where thread strength and surface finish are critical.

What are the specifications of the OSG 1400125001 thread forming tap?

The OSG 1400125001 is a #12-28 UNF thread forming tap with H5 tolerance for 2B-3B class fit. It features a plug chamfer and black oxide cobalt construction for wear resistance. This general-purpose tap is designed for through-hole or blind-hole threading in non-ferrous and ferrous materials.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps like the 1400125001 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact our team for a quote and lead time on this #12-28 UNF tap, available to order through our global sourcing network.

How to select the correct thread forming tap for a job?

Select a thread forming tap based on material type, thread size, and tolerance class. For ductile materials like aluminum or steel, use a plug chamfer tap like this OSG #12-28 UNF. Ensure the hole size matches the tap's recommended pre-drill diameter for proper thread formation without breakage.
