 Self Drill and Tap Screws

FIXING The screws must be fixed at a 90% angle to the sheet and tightened down until the fibre washer shows slight bulging, over tightening can be as bad as under tightening. Large contractors use specialist equipment for fixing these screws. On small contracts electric drills with a socket attachment are used. They MUST have a speed control and a torque control is also advisable for both correct tightness and safety, otherwise sprained or broken wrists are likely to be incurred. Specialist tek guns (electric drills) can be hired from good tool hire companies.
IMPORTANT. If fixing Aluminium or Stainless Steel sheets, Stainless Steel Teks MUST BE USED. In coastal regions subject to salt spray and industrial corrosive environments, the use of Stainless Steel Teks is also advisable.
The quality of tek screws can vary between makes. Zinc Processors Ltd only stock and supply screws from well known quality manufacturers. Below we illustrate some of the many types that we stock and their usage.

	TYPE AB for wood For fixing profile metal sheets to timber purlins. Popular sizes are 25mm and 40mm long. The 40mm is normally recommended for secure fixing. Other sizes are available to order.
	GASH POINT For fixing profile metal sheets to timber purlins. The gash point makes the initial penetration of the metal sheet slightly easier than with the type AB above. Popular sizes are 25mm and 40mm long. The 40mm is normally recommended for secure fixing. Other sizes are available to order.
	STANDARD POINT For fixing profile metal sheets to cold rolled galvanised Z purlins or other relatively soft metal structures. Note the drill bit point and the course threads. Popular size is the 51mm length. Other sizes are available to order.
	LONG POINT For fixing profile metal sheets to thicker steel structures, such as angle iron, box iron and H beams. Note the better quality long point drill bit and the finer securing threads. Popular sizes are 32 and 51mm lengths. Other sizes are available to order. NOTE. All angle iron is not of the same quality (particularly old angle iron). Some contain more nickel than others and is thus a harder steel. This may occasionally result in the head shearing off the screw before it has drilled through the angle iron. The only time consuming  remedy is to pre-drill with a smaller sized conventional metal drill bit.
	STAND OFF GASH POINT For fixing profile metal sheets to timber purlins through insulation materials including composite panels. Note the threads immediately beneath the fibre washer, these are designed to pickup and hold the top sheet in position, otherwise under snow, wind or other loading, the top sheet may slide down the fixing as the insulation compresses under the pressure, breaking the seal. Available in a range of sizes to meet varying insulation thicknesses
	STAND OFF STANDARD POINT. For fixing profile metal sheets to cold rolled galvanised Z purlins or other relatively soft metal structures. through insulation materials including composite panels. Note the threads immediately beneath the fibre washer, these are designed to pickup and hold the top sheet in position, otherwise under snow, wind or other loading, the top sheet may slide down the fixing as the insulation compresses under the pressure, breaking the seal. Available in a range of sizes to meet varying insulation thicknesses.
	STAND OFF LONG POINTS For fixing profile metal sheets to thicker steel structures, such as angle iron, box iron and H beams through insulation materials including composite panels. Note the better quality long point drill bit bit and the finer drilling threads. Note the threads immediately beneath the fibre washer, these are designed to pickup and hold the top sheet in position, otherwise under snow, wind or other loading, the sheet may slide down the fixing as the insulation compresses under the pressure, breaking the seal. Available in a range of sizes to meet varying insulation thicknesses
	STANDARD TEKS FOR FIBRE-CEMENT SHEETING Illustrated is the standard point for use with cold rolled Z purlins. Also available as type AB for timber purlins and as "Stand Off" in various lengths for use with insulation materials. These large tek screws are expensive to purchase, but the vast amount of time and labour cost they save when compared with the use of the traditional Hook or Crook Bolts makes for a considerable cost saving overall.
	SEAM STITCHERS Mini Tek screws with a standard drill point, for side stitching profiled sheets and attaching Ridge Sheets, Barge Sheets and Flashings to profiled sheets etc. 5/16mm head, (8mm) 16 mm washer, length 20mm. For side stitching GRP Roof lights in exposed areas they are available with the larger 29 mm washer.
	STANDARD POINT without WASHER The standard point without a washer is used mainly when sheeting box iron doors and tubular gates as well as any other fixing application where a watertight seal is not required.
	TYPE AB POINT without WASHER for use in Wood Used for any application involving wood where a watertight seal is not required. Example fixing gutter brackets to timber Eaves Beams.
	TYPE B POINT with or without WASHER. These early type B Teks with a blunt end require a predrilled 4.8mm hole and are rarely seen these days. They were mainly used in circumstances were the steel girder etc is too thick or to hard for a conventional self drill tek to drill. SLE Cladding Ltd does not stock them and questions if they are still manufactured. This entry is left in position for information purposes only.
	BONDED WASHERS For all tek screws. Whilst 19mm is our standard stock sizes fitted to the above screws, 16mm & 29 mm washers can be ordered as separate washers or fitted to most of the above screws. The 29mm washer is particularly useful for fixing roof lights in exposed areas.
	PUSH ON COLOUR CAPS. Available in 5/16" (8mm) hexagon head to suit 16mm, 19mm, & 29mm washers. Stock items are the 12 BS standard colours in 5/16 (8mm) head with 19mm washer.   Other BS. and RAL colours are available to order. Please specify BS. or Ral. number.
	DRIVE SOCKET. To fit any electric drill. Both 3/8 and 5/16 heads available. Drill MUST have a speed & a torque control for both correct tightness and safety (To avoid sprained or broken wrists) A Tek Gun (electric drill) can be hired from any good tool hire firm.
With the Type AB Tek for wood, some people use them as nails, driving the Tek home with a hammer. This method risks the tek screw not being at a right angle to the sheet and thus not sealing. Using the thicker 0.55 and 0.7 mm thick sheets there are risks of the screws forming depressions in the sheets were the washers will sit before penetrating the sheet and thus not producing a watertight seal or a waterlogged seal. Only consider using a hammer where a watertight seal is not needed. If you have to use teks as a nails on say a small emergency repair, see that the tek is at a right angle to the surface and  finish tightening the teks with a socket on a ratchet spanner to the correct tension.
