Description
Condition
Used (Like New / Complete Set).
This pin gauge set is in excellent used condition. While the outer case may show minor signs of storage, the pins themselves are pristine. Key Detail: The set is 100% Complete (no missing pins), and most individual pins are still sealed in their original protective plastic sheaths, indicating they have likely never been touched or used. Supplied with original papers.
Product Overview
The SK (Niigata Seiki) PG-2A is the direct follow-up to the PG-1 series, covering the larger measuring range of 6.300mm to 9.775mm.
Like the smaller set, this kit features the specialised 0.025mm step increment. This fine resolution allows for highly accurate “Limit Gauging” (Go/No-Go testing). For example, it is perfect for checking valve guides, reamed holes, or precision bores where a standard 0.01mm step set might be too fine, but a 0.1mm step set is too coarse. The pins are 50mm long, hardened to HV650, and sub-zero treated for dimensional stability.
Brand Information
