Replacement Bit

These coated fasteners possess a level of corrosion resistance that makes them suitable for use in some exterior and corrosive environments and with some preservative-treated timber.
For applications in higher-exposure applications, consider Type-300 series stainless-steel fasteners for superior corrosion resistance. Bit(s) included with every box of screws.
Pre-drilling and countersink may be necessary at ends, butt joints, and on applications where denser material is used. Follow board manufacturers recommendations where applicable.
