Product Description

Introduction

1. GO & NOGO, RH(ring hand)  & LH(left hand) available
2. As these UNS thread gages is special, so most of them are not in stock, these gages need custom production
3. Standard tolerance: Thread plug gauge 2B/3B &  ring 2A
4. Classes 2A and 2B are the most commonly used for general applications, including production of nuts, screws, and bolts.
5. Internal thread tolerance class: 1B,2B,3B;
6. External thread tolerance class: 1A,2A,3A
7. 3A 3B will be used when closer tolerance required.
8. Material: GCr15
9. For special gauges without stock, we can provide special custom production service,  one pc is also acceptable,
10. All our UNS thread ring gages and plug gages are manufactured compliance to standard: ASME B1.2

• Material:Oil hardened tool steel-Gcr15, high wear resistance.
• Hardness: 58-62 HRC
• Ring gages are solid; Plug gauges are Taperlock- double ends with one handle. our solid ring gages can be used directly, no need setting plug gages to test them in advance. The advantage of Taper-lock style is when one end worn out, one new end can be replaced quickly and easily.The handle and end in good condition can be used again.
• All gages are 100%New
• Gage manufacturer ISO9001 certified
• gaugestools know the importance of controlling temperature and humidity when testing gages, the temperature will be 20 degree +- 0.5 degree, the humidity will be 45%-65%.
• Long form calibration certificate from ISO17025 accredited lab can be provided, but it need to be told in advance, and need extra costs.
• We can provide laser marking service on the gauges. For example, clents' Logo.
