Woodworking Fasteners And Hardware

Question 1

What is the primary purpose of drilling a pilot hole before driving a screw into hardwood?

Accepted Answer

To prevent the wood from splitting

Answer

Pilot holes reduce stress on wood fibers as the screw enters, preventing cracking or splitting that commonly occurs in dense hardwoods.

Question 2

Which nail type has the smallest head, making it ideal for finish carpentry where the fastener must be concealed?

Accepted Answer

Brad nail

Answer

Brad nails have a very small, nearly headless profile that can be set below the surface and covered with wood filler, keeping the finished surface clean.

Question 3

What does a higher gauge number indicate when selecting nails?

Accepted Answer

A thinner nail shank

Answer

In nail gauging, higher numbers indicate thinner shanks — a 23-gauge pin nail is much thinner than a 15-gauge finish nail.

Question 4

Which screw drive type provides the best resistance to cam-out (bit slipping) when driving screws?

Accepted Answer

Torx (star)

Answer

Torx screws feature a six-pointed star recess that maximizes contact between bit and screw, virtually eliminating cam-out during driving.

Question 5

What feature of a carriage bolt prevents it from spinning when the nut is tightened?

Accepted Answer

The square shoulder under the head embeds into the wood

Answer

Carriage bolts have a square shoulder just below the rounded head that embeds into the wood surface when tapped, locking the bolt against rotation while the nut is tightened.
