If you use a Senco DuraSpin collated screw nailer (like the popular DS275-18 model), you know the insert bit that drives the screws can wear out or break.

This Senco EA0143 pack gives you five fresh replacement bits.

They're 1-inch long with a 2-square drive (that's the shape that fits into the tool's chuck).
They're designed to work with all the DuraSpin models, so they're a universal spare part for that system.

The pack even includes a little installation wrench to help you swap out the old bit for a new one.
Having a few spares on hand is a smart move for any pro or serious DIYer – it keeps your job moving when a bit gets dull or snaps.

A simple, genuine Senco part that ensures your nailer keeps performing like it should.
