TORK SCREWS, Officially

Torx Screws, were first developed in 1967 by Camcar/Textron and the Torx Drive System was patented by them. Seventeen years later (1983/1984) when the patent expired for Torx Screws, many manufacturers started making Torx Drive products, but because Camcar/Textron maintained the trademark "Torx", the new products were called 6-Lobe Screws. On this Website we have both, the genuine Torx Screws and 6-Lobe Screws, also referred to as Star Drive Screws.

We believe that we have the largest inventory of Torx® Drive screws on the PLANET.

This web site is designed with four sub-pages to the home page and each of the sub-pages is dedicated to four different types of Torx Drive Products. Just under the pictures above you will see these four categories of Products. The first category is Torx Machine Screws and Torx Cap Screws. The sub-page dedicated to these products can be found at:

Torx Screws

The second category is the machine screw threads, Taptite type trilobular screws and the Plastite type trilobular screws at:

Torx Thread Forming Screws

These screws are also called Torx Thread Rolling Screws.

The third category is the:

Torx Self-Tapping Screws

which are often referred to as Torx Sheet Metal Screws. They come in Type A, which have wood screw type threads with a sharp point and the Type AB, which is essentially the same as the Type A but has about 10% more threads.

The fourth is the:

Torx Thread Cutting Screws

which are often referred to as Type F Thread Cutters. These screws are also referred to as Torx Floorboard Screws.

Torx Screws are becoming a world standard.

It turns out that most metric oriented countries such as Europe and Asia have fully embraced the Torx Drive System and most other screw drive system forms are becoming obsolete.

The worldwide automotive market has adopted the Torx Drive System almost exclusively. In 2005 an ISO specification was released for worldwide consumption as ISO 10664.  It specifies the shape and basic dimensions of the hexalobular internal driving feature for Tork Bolts and Tork Screws, including the gauging method. This specification is intended to provide the details necessary for inspection of the hexalobular driving feature and is not necessarily suitable as a manufacturing standard. If you are interested in getting a copy of this Torx Screw specification, we will send it to you at our cost of $70.00 USD as we are unable to copy it due to the restrictions of copyright law.

Features and Benefits of the Torx Drive System.

It features a 15 degree drive angle which provides high torque transfer. Radial forces are drastically reduced resulting in longer tool life. The Torx Socket Drive Screws has been reported to be five (5) times better than an equivalent Hex Socket Drive Screw. It has vertical sidewalls which increases tool engagement. Unlike cruciform (Phillips) drive systems, no camout forces are created to push the driver up and out of the fastener recess. Since camout is virtually eliminated, little or no end load is required. Ergonomic studies have shown the Tork Screws of the Tork Socket Drive System can reduce fatigue and muscular stress during the manual assembly of fasteners. The recess completely encloses the drive bit, minimizing tool slippage and the damage and injuries it can cause.

CAMOUT is not a problem with Torx Drive System

CAMOUT is defined as the force upward on a screwdriver as the torsional force is increased in order to tighten the screw. Torx Screws do not have camout problems.

You must bear down extremely hard in order that the screwdriver will not rise up and leave the recess altogether. Because of the large angle on cruciform (Phillips) screwdrivers, it becomes virtually impossible to bear down hard enough to keep the screwdriver in the recess in some cases. When the screwdriver cams out, it will usually damage the recess of the screw and because of the pressure applied, it can damage the surrounding material around the screw. The two problems of driver fatigue due to having to applying such high pressure on the screwdriver and the large angle of the cross recess (Phillips) screwdriver is solved with the Torx Socket Drive System. The small angle of 15 degrees for the Tork Socket Recess virtually eliminates CAMOUT and reduces significantly the pressure required to keep the screwdriver in the socket and therefore reduces operator fatigue.

Let Aaron's 15 web site stores be your single source for Torx Drive System products.

We have dedicated this web store just for Torx Screw users. Over the past 10 years we have processed over 22,000 customer orders and many of those were for Torx Screws. However, a significant number of our customers insist on calling Torx Screws either Tork Screws or Torks Screws. Therefore, we built this web site for those customers who want to use the name Tork Screws or Torks Screws. This Tork Screws web site shares the same database with Aaron's 6-Lobe Screws, but you can place your orders right on this web site. We now have three web site stores dealing with Torx Screws, 6-Lobe Screws, 100 Degree Flat Head Six Lobe Screws and this web site for the convenience of ALL of our customers. If we do not have the item you want in our current inventory when you place your order, we will manufacture it and guarantee you that we will have it in inventory the next time you order that item. We are currently running at a 96% fill rate in our warehouse and our manufacturing lead time is as little as 10 days for small quantities in really urgent circumstances.

We are experts with the Torx Drive System and we can help solve any of your fastener problems and help you to convert from some other drive system to the Torx Drive System very quickly. Our technical staff can also help you solve technical problems in special applications. It is our prediction that Torx Screws will become the defacto standard in the US in 15 years and in the entire world in 25 years. We already have over 40,000 different head styles, sizes and material which results in over 55,000,000 screws.

A carton may be 10,000 pieces for a physically small item but may be as few as 2,500 pieces for larger items. Our warehouse operates a "breakdown facility" where cartons are broken open to ship quantities of 10, 100, 1,000 (or multiples thereof) but major discounts are given for full carton orders. Because we are a volume warehouse supplier of Torx Products, we reward customers for volume business.
