Counteract Replacement Brush for the 16-401 Tool (14 mm)
Fits the 16-401 tool | Dense, evenly packed bristles | Thick collar with ribbed edges
The Counteract replacement brush is a round wire insert that fits the 16-401 tool for mechanical cleaning of bolt and stud threads (14 mm). Metal bristles cover the inside of the brush evenly, while a thick plastic collar with ribbed, reinforced edges keeps it firmly seated in the cleaning holder.
What this brush is for
The brush is the wear part of the 16-401 tool — it does the actual thread cleaning, while the tool body guides it along the work. Dense, evenly spaced bristles reach the thread around its full circumference, so a corroded or dirty surface can be cleaned with little effort from the operator. The solid wire construction and thick collar keep the brush seated firmly in the holder even during heavy use.
