FAQ | Purchasing Questions

Spiralock gages are more expensive than standard gages, however, total costs for Spiralock should be factored into the purchase equation. When this is done, there is usually less total cost associated with using Spiralock.

Several factors should be taken into account:

1. Spiralock gages are not mass produced; consequently, they cost more than standard gages.

2. Additional manufacturing operations which have a greater degree of difficulty are required to produce Spiralock gages.

3. A three-member gaging system is used for the majority of Spiralock threads as compared to a two-member gaging system (GO and NOT-GO) for standard threads.

4. Great care is taken by Spiralock Corporation to build high quality gages with standards traceable to the National Institute of Standards & Technology.

Spiralock tools cost more than standard tools, however, in most cases the extra expense is offset by the added benefits of using this unique thread form. In fact, after factoring in the elimination of another locking device, subtracting the labor for applying it and reducing the inventory cost for stocking it, Spiralock can often offer substantial cost savings.
