Description

Security Torx has its own set of variations, and many other variations of Torx drives are available in Security or TR versions. The diagram depicts the interaction between the male and female components of a conventional hex drive and a Torx drive. Torx Paralobe is a further developed Torx Drive System with 6% longer Flanks which results in a 20% higher applicable torque. The green circle, passing through the six points of contact between the two components, represents the direction of the rotational force being exerted at each of those points. The Torx design allows for a higher torque to be exerted than a similarly sized conventional hex socket head without damaging the head or the tool.

Principles of operation [ edit ] The angle between the plane of contact between tool and fastener and the circumferentially directed force is much closer to 90° in a Torx type of head (lower) than in a conventional hex head (upper). The official generic name, standardized by the International Organization for Standardization as ISO 10664, is hexalobular internal.Torx head sizes are described using the capital letter "T" followed by a number ranging from T1 to T100. Initially, they were sometimes used in applications requiring tamper resistance, since the drive systems and screwdrivers were not widely available; as drivers became more common, tamper-resistant variants, as described below, were developed.

All applications are assessed individually by Klarna and decisions are based on individual circumstances. Although the brand "Torx" generally refers to the standard 6-star-driver or -socket, there are many variations to the original design, including a number made or licensed by Torx. p>

The "E" numbers are different from the "T" numbers of the same size: for example, an E4 Torx socket fits a T20 head. A smaller number corresponds to a smaller point-to-point dimension of the screw head (diameter of circle circumscribed on the cross-section of the tip of the screw driver). Other tool manufacturers have been producing 8-, 10- and 12-point star drivers and sockets for many decades. strong>

    National Tyre Service Ltd t/a National Tyre and Autocare is not authorised or regulated by the Financial Conduct Authority. A version known as Security Torx, Tamper-Resistant Torx (often shortened to Torx TR) or pin-in Torx contains a post in the center of the head that prevents a standard Torx driver (or a straight screwdriver) from being inserted.

    This property allows the head of the fastener to be smaller for the same required torque, which can be an advantage in applications where space to accommodate the head is limited. The name is shortened to IP (Internal Plus) with sizes ranging from 1IP to 100IP [18] (sometimes listed as IP1 to IP100 [19]) and EP (External Plus) with sizes ranging from 1EP to 42EP as well as smaller sizes ranging from H7EP to H2EP and includes five-lobed tamper-resistant variants.
