Hammers

Introduction to Hand Tools 00103-15

Hold the hammer with the end of the handle even with the lower edge of your palm. Keep your eye on the nail head!

Hammers

Introduction to Hand Tools 00103-15

Ball-peen hammers should not be used to hammer a nail, since the steel is tough but not as hard.

Hammers

Introduction to Hand Tools 00103-15

Sledgehammers are heavy and require a lot of effort to swing. Start with lighter blows until you achieve a rhythm.

Chisels and Punches

Introduction to Hand Tools 00103-15

Cold chisels are designed for working with metal. Many wood chisels are designed to be tapped with a mallet, but others are

designed only for use by hand.

Chisels and Punches

Introduction to Hand Tools 00103-15

Center and prick punches have different tip angles. Pin punches (not shown here) have straight and round shafts and

are often used to drive connecting pins out.

Screwdrivers

Introduction to Hand Tools 00103-15

Each screw drive type has its own advantages. Some are popular for woodworking while others have more varied purposes.

Page 12: Common hand tools

Screwdrivers

Introduction to Hand Tools 00103-15

A slotted screwdriver that does not fit the screw head is likely to result in damage to the screw and possibly the workpiece as well.

Wrenches

Introduction to Hand Tools 00103-15

The correct wrench fits the hardware snug, provides enough leverage for the task, and can be

manipulated in the space available.

Page 14: Common hand tools

Wrenches

Introduction to Hand Tools 00103-15

Spud wrenches are very handy if you are often working with large valve caps or plumbing

fixtures.

Page 15: Common hand tools

Sockets

Introduction to Hand Tools 00103-15

Sockets and ratchet drives are very popular due to their versatility and speed.

Page 16: Common hand tools

Sockets

Introduction to Hand Tools 00103-15

Torque wrenches allow the user to apply a specific amount of twisting power to the hardware.

Some digital models can hold settings and torque events in memory.

Pliers

Introduction to Hand Tools 00103-15

Each type of plier and jaw shape is best for specific uses. Locking pliers can free one hand by standing in as a clamp.

Page 18: Common hand tools

Tape Measures

Introduction to Hand Tools 00103-15

Tape measures, or measuring tapes, are great for measurements for a range of lengths. Folding rules are usually 6 feet or 2 meters

long and remain rigid, which has its advantages as well.

Squares

Introduction to Hand Tools 00103-15

A pipefitter’s square looks like a carpenter’s square from a distance, but the tables and formulas marked on it are

different. They are best for large stock and checking framing.

The combination square can mark 90-degree angles and … …45-degree angles. It is limited somewhat by its size and design to scribing lines rather than checking framing for a

square condition.
