Yardblaster arms don't have thru-bolt flanges. If it has a thru-bolt flange, it's a regular street light mounting arm or a NEMA head arm (NEMAs and yardblasters are different lights, the former being a utility-grade light used on wood poles and the latter being a residential knockoff).
Yeah, you can install a regular arm onto your house. Replace the thru-bolt with a 5/8" lag bolt instead and use 1/2" lag bolts for the lag bolt flange.
