Torx Screw and Star Socket Size Chart

Torx Socket Screw what?

 

In 1967, Camcar Textron patented the Torx screw (also known as the star socket screw), a trademarked type of screw head characterized by its imprint—a star with six points. It is widely used in the automotive and electronics industries, as well as in motorcycles, bicycle brake systems, and in 3C products, including the iPhone.


The popularity of Torx socket screws and Torx socket sets has increased over the years and will likely continue to grow. Not only is the star-shaped design tamper resistant, it saves time and prevents wear. As compared with a conventionalhex socket head of the same size, a Torx screw can withstand a much higher torque without sustaining damage to its head or its socket.

The hand tools for disassembling Torx screw could be divided into 2 series: Torx socket (star female) or Torx Bit (star convexity male).


As a leading manufacturer of quality sockets, Tien-I pays careful attention to the angle of the Torx hole. As Torx nuts have different drive angles from standard nuts, a quality Torx (or star) socket must have the optimal angle for the Torx socket screw.

 

Torx Screw Angle


Tien-I produces all types of star sockets (also referred to as E sockets), including chrome and impact sockets in sizes ranging from ¼-inch to ½-inch. If you have any questions aboutstar sockets,star screwdrivers,tamper-resistant star sockets or star impact sockets, please contact our friendly and knowledgeable team.  We also make various type of impact socket bits and full range of bit sockets and bit socket sets, so if you need other custom bit socket, don't hestiate to contact our sales team.

“ It feels this socket not griping tightly.  How to check the size of Torx screw?


These kind questions can be heard in every hardware stores.  We hereby provide helpful information on Torx Screw and Start Socket, aka E socket. Hope every professional craftsman can always buy the right star socket.

What is the difference between impact socket and chrome socket? Why is CR-V material not suitable at producing impact sockets?

Tien-i's hand sockets are made of Cr-V steel (CR-V).

Compared with the raw material "CR-V" for hand sockets, the raw material for pneumatic sockets, CR-MO, has stronger toughness, i.e. stronger shock resistance. Suitable for use with air and electric guns. CR-V steel (CR-V) has higher hardness, but in the need for shock-resistant use environment will lead to reduced service life.
