Washers
Washers
Washers are thin circular – and sometimes square – pieces of metal with a hole in its centre used in conjunction with screws or bolts to distribute the load the fastener is applying to an object.
Types available
Spring washer
- A washer with a split at one point, giving it a helical shape.
- The washer’s shape causes it to exert a spring force between the fastener’s head and the substrate.
- The spring force then creates friction and prevents the fastener from coming loose.
Extra information
If the spring washer is too small to span over the distance of a hole, a large flat washer and a Nyloc nut should be used instead.
Cup washer
- Used in combination with countersunk screws, such as Cut screws or self-tappers, to obtain a finished look.
- The washer also increases and spreads the grip the fastener applies once it’s screwed in place.
Square washer
- A square washer, as its name indicates, is a large square washer with a round centre hole.
- These washers are specifically designed with heavy-duty fastening in mind.
- The washer’s large size allows it to, evenly and effectively, distribute the load applied by the bolt, underneath the bolt’s head.
- Square washers are more durable than their round counterparts.
- They are mainly used in the building industry as it can withstand stress and vibration better than round washers.
- During the construction of decks, square washers can be used during the construction of the decking structure because it experiences a lot of vibrations, movement and use.
Flat washer
- Used to spread the load of a fastener (screw or bolt) when it’s fastened to a substrate.
- Available in sizes small, medium and large.
