See our privacy policyTorx drive tek screws are increasingly becoming more and more popular due to the high torque capabilities of torx as a drive recess. The six-lobe pin design gives the user much more drive torque than the traditional pozi or phillips drive screws, and another benefit of the design is a much-reduced risk of tool slippage during insertion. We have significantly increased both our stock range & stock levels of torx drive tek screws in the last few months, and this is only set to continue as we sell more of these and less pozi/phillips drive.
The below table is a useful reference table of DIN 7504 specifications for torx drive.
One thing you must bear in mind with Torx drive tek screws, is that there are numerous drive sizes (as many as 10 common sizes are widely in use), whereas with pozi and phillips, this is limited to 3 common sizes. The good news is that using the reference chart below, you can easily see what drive size you need for each screw size, and we keep all common sizes in stock so if you don’t have the size you need you can add to your order.
