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 styles of heads available. |

|
| Fastener Head Styles |
| The style of the fastener head determines the shape of the tip of the tool that is used to drive (turn) the screw or bolt into place. There are many different types used on different scales of model cars and many of these are identified below. |
| Each different fastener head is shown along with a screwdriver type tool tip that would be used to drive it in or out. |
| Slotted/Straight Head |
|
|
The slotted or straight headed style of fastener head is the oldest and by far the most simple type available. It is used mainly for adjustment screws on the engines of radio controlled model cars, as the slot gives a clear indication of the position of the adjusting screws. |
|
| Philips/Cross Point Head |
|
|
The Philips or cross point fastener head is used extensively on radio controlled model cars and offers better performance than the straight type head style. This is because the contact points between the tool tip and the recess in the fastener head are doubled. |
|
| Pozidriv/Supadriv Head |
|
|
The Posidriv or Supadriv head is an improvement on the Philips/cross point head and offers better performance due to the contact points being effectively doubled again. This is also one of the most popular fastener head styles used on radio controlled model cars. |
|
| Hexagon Head |
|
|
The hexagon fastener head type is the original of its type and is usually used on bolts or set screws. Its use on remote controlled model cars is not widespread and is usually most used on the large scale cars and trucks. Although a socket can be used, (as shown to the left) spanners are more commonly used to turn hexagonal headed fasteners. |
|
| Allen Head |
|
|
The Allen fastener head style is used on remote controlled model cars in areas where secure holding of parts is required. The fasteners with the Allen type recess are usually hardened to offer the required performance. |
|
| Torx™ Head |
|
|
The Torx™ type fastener head style is the newest available for use on radio controlled cars and offers the highest contact point area of all the fasteners mentioned here. As such, it offers the greatest performance for the model car racer and is useful for engine mountings, etc.. |
|
| Other Fastener Head Syles |
| The fastener head styles introduced in this article represent the majority of those that are likely to be encountered by the remote controlled model car racer. |
| There are many others available such as Spline types, which are similar, but not compatible with, the Torx™ style of fastener heads. 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. |
