Kevin Moorcroft explains some features of different screw drive types<\/strong><\/p>\n\n\n\n

Anyone regularly using simple slotted drive screws – with a traditional straight bladed screwdriver, will be aware of its shortcomings – with a power driver then even more so. <\/p>\n\n\n\n

The old-style slotted drive will \u2018cam-out\u2019 easily, is almost impossible to centre and if the tool or slot is even slightly worn, then is extremely different to install or remove.<\/p>\n\n\n\n

Consequently, with the need in industry for a faster, more reliable approach a variety of different styles are now available from suppliers such as Challenge Europe.<\/p>\n\n\n\n

The first seems to have been the Phillips – a cross-head design centred in the screw head with a matching drive tool, either manual or powered. <\/p>\n\n\n\n

The sides of each blade are slightly tapered and rounded so that the tool will rise out of the cross-head rather than break off the head. <\/p>\n\n\n\n

However, this limits tightening torque which led to the Pozidrive screw with flat sides and a more sophisticated design so as to engage more firmly with the driver, enabling much higher torque values to be achieved.<\/p>\n\n\n\n

Importantly, the self-centring action of these drive styles greatly aids ease and speed of use, either manually or in automatic feed systems.<\/p>\n\n\n\n

A more recent development is the six-armed star TorxT approach which is a precision parallel-sided design for higher torque and finds great popularity in the motor vehicle industry.<\/p>\n\n\n\n

Interestingly, one of the oldest head styles and still one of the highest performing and commonest is the hex drive – with internal socket formed in the head or with external hexagonal shape to accept a socket wrench tool.<\/p>\n\n\n\n

Internal hex drives, often referred to generically as Allen key drives, are a precision drive with high performance, available in an extensive size range. <\/p>\n\n\n\n

Whereas the traditional external hex head is commoner on lower cost bolts and setscrews. <\/p>\n\n\n\n

Both offer stability in operation but often need some \u2018help\u2019 in centring. This is commonly achieved by providing a spherical end to the drive for an internal hex or a chamfered lead-in on an external hex head.<\/p>\n\n\n\n

Machine screws, bolts, self-tappers, self-drilling screws and woodscrews are all available with at least 2 or 3 of these drive styles and making the right choice can make or mar an installation or assembly process. <\/p>\n\n\n\n

In case of doubt, consulting with your supplier is always advised.<\/p>\n\n\n\n
