Counteract Replacement Brush for Tool 16-402 (22 mm)
Fits the 16-402 tool | Dense, even bristles | Secured with three screws | Sold per piece
The Counteract replacement brush is a round wire insert that fits the 16-402 mechanical thread cleaning tool for bolts and studs (22 mm). Metal bristles evenly cover the full interior of the brush, and a thick plastic collar with ribbed, thickened edges holds it securely in the holder.
What this brush is for
The brush is the wear part of the 16-402 tool — it's what actually cleans the thread, while the tool body handles centring and drive. Densely and evenly spaced bristles wrap around the thread across its full circumference, letting a corroded surface get cleaned with minimal effort from the operator. The brush is secured in the holder with three screws, and the whole assembly mounts onto a grinder or other tool using the adapter included with the matching holder. The best cleaning results come at low grinder speeds — higher speeds don't speed up the result and can accelerate bristle wear.
