The Ball Pein hammer is used mainly by engineers. It is a general hammer, but has certain specific uses. One such use is cold riveting. |
BALL PEIN HAMMER EXAMPLE |
The images below show cold riveting using a ball pein hammer. Notice how both faces of the hammer head are being used. The ‘ball’ face is used to form the head of the rivet and the flat face applies the force to the rivet set, closing the gap between the two steel plates. |
CROSS PEIN AND STRAIGHT PEIN HAMMER EXAMPLES |
The cross pein hammer has many general uses. One of the most common is hammering nails into wood. The hammer is ideally weighted and balanced for this type of work. If hammering a nail in a restricted space, the cross pein can be used, to transfer the force from the hammer to the nail. Greater care is needed if using the hammer in this way, as it is more likely to slip off the head of the nail and damage the surface of the material or hit hands and fingers. |
The straight pein hammer has exactly the same uses as the cross pein. However, there are times when a straignt pein is suitable, because of the nature of its design. It is worth noting that straight pein hammers are less common than the ‘cross’ type. |
