Handbook - Fastening
- Use 8d nails designed for wood trim and siding that have thin shanks, blunt points and full round heads with annular threads.
- Fasteners must penetrate a full 1 1/4" into substrate. (stud or joist)
- If you can bend a fastener (16 ga. or 18 ga. trim nail) between your fingers, it is too thin.
- Fasten 2” maximum from end of board. (3/4” preferred)
- Stainless fasteners are preferred over galvanized, as there’s less chance of corrosion. (galv. stripping off fasteners)
- Nail guns can be used – PSI between 80-100, dependent upon gun, nail, outside temperature, and substrate.
- Use 7d trim screws for optimum hold strength.
- In temps under 40°F, pre-drilling may be required. Consider using screws at low temperatures.
- Avoid brads, staples, ring shank nails, or fine threaded wood screws on all trimboards. They will not provide the necessary holding power.
- 1/2” Stealth Beadboard can be blind fastened with 1/4” wide x 1” deep galvanized staples.
