This section of the RcTek site is devoted to informing the radio controlled model car racer about the various fixings & fasteners that are used in remote controlled model cars.
In this article we have information for the model racer about the various shapes of heads available. |

|
| Fastener Head Shapes |
| There are many different shapes of fastener heads used in the radio controlled model cars available today. The vast majority of these are identified below, although we cannot cover every different variation. |
| Almost all of the fastener head shapes are available in different Head Styles, this if course depends on your location and manufacturer. Also, the names that have been used to describe the shape of the heads may be different in your area of the World. |
| Countersunk Head |
| The countersunk headed screw is the most common type used by model car manufacturers and provides a flush fitting fixing that can help in the alignment of the parts it is used on. |
|
| Raised Countersunk Head |
| The raised countersunk type of fastener head is functionally the same as the countersunk variety and offers a deeper and therefore stronger recess that is neater in appearance. |
|
| Cheese Head |
| The cheese type fastener head is so called because of its likeness to a block of cheese and provides an inexpensive fastener solution. |
|
| Round Head |
| The round type of fastener head is more decorative than functional as far as its use in model car is concerned, but has been included for completeness. |
|
| Pan Head |
| The pan type of fastener head is so called due to its likeness to the inside of a frying pan and provides a reasonably low profile fastener. |
|
| Flanged/Washer Head |
| The flanged type of fastener head makes advantage of the combining of a washer and a pan head into one unit. The resulting fastener head is lower in height and provides a greater contact area on the part it is screwed into. |
|
| Hexagonal Head |
| Although the hexagonal type of fastener head is generally the most used in the world, its use on remote controlled model cars is limited due to, amongst other things, the weight saving advantages of the alternatives shown in this article. |
|
| Allen Cap Head |
| The Allen fastener head shape is used on remote controlled model cars in areas where secure holding of parts is required. The heads are smaller than the rest of the head shapes in this article and are usually hardened. |
|
| Allen Button Head |
| The Allen button head fastener head shape is a low profile alternative to the Allen cap type of head, but uses a relatively smaller hexagonal recess. Due to the lowered height, the recess also shallower, which can lead to problems with 'rounding off' of the recess due to excessive forces being applied. |
|
| Other Fastener Head Syles |
| The fastener head shapes introduced in this article represent the majority of those that are likely to be encountered by the remote controlled model car racer. As the model car racer is unlikely to have to deal with these other types, they will not be covered. |
| Summary |
| That concludes this article and you will now hopefully be better informed as to which types of head you are likely to encounter in the radio controlled model car hobby. |
