Why SMART-BITŪ?
Decks have undergone an
evolution in recent years, from being part of the backyard to
part of a home's primary living space. Along with this change
has come the expanded use of preferred decking materials like
composites and hardwoods. Stainless steel deck screws, long
recognized as the fastener of choice for high-end decks, have
also witnessed expanded use.
Stainless steel, however, is softer than
hardened steel and often requires pre-drilling with preferred
decking materials. In the past, pre-drilling was time
consuming and laborious. But with the introduction of the
original SMART-BITŪ, pre-drilling and countersinking could be
done in one step, with one tool, more quickly and more easily
than ever before. That's smart!
And now, SMART-BITŪ is even smarter!
The new SMART-BITŪ has POWERBOLICŪ drill bits with special
fluting that cuts through decking more than twice as fast as
standard wood bits. Plus, the bits are replaceable!
For deck builders working with composites,
SMART-BITŪ offers an additional benefit -- it eliminates
mushrooming (the formation of small mounds of waste material
near the screw hole surface).

*Note:
- Overall hole depth including
countersink portion.
- When installing decking it is
general practice not to pre-drill the underlying (joist)
material, as this is usually treated timber and does
not require pre-drilling. The 1-1/8" overall hole depth of
the #8 Trim and #10 Flat sizes provides sufficient
depth for installing deck timber up to 5/4" nominal
