Torx Security Screws

What is Torx®?

Torx® is a trademark for a specific type of screw head and was developed by Camcar LLC, a division of Acument Global Technologies. Torx screws are characterized by their unique star-shaped (six point) pattern. There are various benefits associated with the star design, including preventing cam-out and an increased ease in maintaining a consistent torque.

*Torx screws are available in both secure and non-secure varieties. In both cases, Torx screws are identifiable by the unique 6-point star-shaped head design. TorxPlus products are slightly different: learn about TorxPlus security products.

Torx Security Screws

Originally, general Torx products were fairly tamper-resistant because the associated screwdrivers and drive systems were largely unavailable. This changed, however, as the use of Torx products became increasingly common. Therefore, specific tamper-resistant varieties were developed. A Torx tamper-resistant screw contains a solid post formed in the middle of the recess during the heading process. This solid post blocks the insertion of an ordinary Torx screwdriver (or other driver), making these fasteners nearly impossible to remove without a unique tamper-resistant tool. Torx tamper-resistant screws are made from either 18.8 stainless steel or heat-treated alloy steel with zinc plating. Torx tamper-resistant fasteners are available from Tanner are cap screws, sheet metal screws, self-drilling and concrete screws.

*TorxPlus tamper resistant screws are the other variety of Torx security screws.

Types of Torx Security Screws

They are various types of Torx security screws, each type with its own set of unique features and intended uses. The following descriptions outline some of the major features and uses for two popular Torx security screw types:

Torx Tamper-Resistant Sheet Metal Screws: This type of screw has a solid post in the center of the head. They are extremely difficult to remove with a specific tamper-resistant tool and are used extensively in correctional facilities, hospitals, educational buildings, public buildings, and retail stores. Sheet metal screws are case-hardened with a zinc finish.
Torx Tamper-Resistant Cap Screws: Include many of the same security features as Torx tamper-resistant sheet metal screws: have a solid post in the center of the head, are extremely difficult to remove without the proper tools, and are used in facilities where tamper-proofing is essential to reduce vandalism, tampering, and theft. Torx tamper-resistant cap screws, however, are manufactured from either heat-treated alloy steel with zinc plating or 18.8 stainless steel.
Torx Tamper-Resistant Self-Drilling Screws: These screws eliminate separate drilling and tapping operations for faster, more economical installations and provide a sharp, clean and consistent drill point assuring excellent thread engagement and holding power. Available in button, pan, flat and oval heads in case hardened zinc plated steel and 410 stainless steel.
Torx Tamper-Resistant Masonry Screws: This screw uniquely unites the security features of Torx tamper-resistant screws with the advanced quality and the simple installation advantages of an UltraCon masonry screw. Twin-leaded threads mechanically link to masonry allowing for increased joint integrity. The sharp, high thread cuts deeply and easily due to a notched edge. The alternating low thread provides stability for fast, accurate driving. Fast and accurate driving is accomplished by way of the alternating low thread. The screws have a Stalgard® finish to accord vastly improved resistance of salt spray (1000 hours with no red rust per ASTM B117).
