This is a genuine Mac Tools brand replacement part: a steel hammer case/nose housing, item #234-A727, for use with the Mac Tools 1/2-inch drive pneumatic (air) impact wrench model AW234.

This item is used, but in good working condition. It does not come with screws.

Note that this is an older style part, and not the newer part #234-A727A.

We also carry an aluminum version of this hammer case/nose housing (same part number), for the same price--see the following link:
