Type, Size and Spacing For best results use "splitless" siding nails. These have thin shanks and blunt points to reduce splitting. For greater holding power, nails with ring threaded or spiral threaded shanks are recommended. Nails with textured heads can be used to reduce glossy spots at the nails when finishing (see figure on right for nail types). Nails should be driven with care. Heavy nailing distorts the wood and may cause splitting. At mitered corners, near edges and near ends, nail holes may need to be pre-drilled to avoid splitting.

Siding should be fastened to each stud or furring strip with nails spaced at a maximum of 24" (61cm) on center, nail placement depends on the siding pattern and width. The key is to fasten the siding securely without preventing it from moving in response to the moisture content of the air. In general, each piece of siding must be nailed independently.
