Best Torx Screwdrivers And Torx Screws For 2020
Camcar Textron invented the Torx screwdriver in 1967. Camcar Textron was a tool manufacturing company located in the U.S.A.
Textron designed the t8 torx security bit screwdriver to prevent camming out. Slotted and Philips head screws were designed to cam out when they are over tightened. Textron designed the Torx screw to prevent this.
Camming out happens when the torque of the driver is more than what the head of the screw was designed for. The driver will slip out of or jump out of the head of the screw. This ends up damaging the tip of the driver and the head of the screw.
The Torx design prevents the camming out of the driver and screw head since there is more contact between them.
Since they are more locked in when being used, as a result reducing wear and tear on both of them, Torx drivers and Torx screws tend to last longer.
A Torx design is a pattern that has 6 points and is star shaped. Hence a star screwdriver, star tool, star bit, torques screwdriver, and torque bit are other name for Torx drivers.
Tamper-Resistant Torx, Torx TR, and pin-in Torx are all names for Security Torx drivers and Security Torx screws.
A normal Torx driver is just the same as a Security Torx driver but has one small difference.
A Security Torx driver has a small hole drilled into it.
A security Torx screw also is different from a normal Torx one since it has a raised pin in the middle of the star pattern.
Therefore, a Security Torx screw can’t be used with a normal Torx driver because of the raised pin in the Security Torx screw which prevents it from fitting.
Consequently standard sizing for both Torx and Security Torx drivers is the same. They both use the letter T with a number after it. T1 is the smallest Torx driver with T100 being the largest.
There is also an External t8 torx security bit screwdriver. This is used for screws that have a Torx head and uses an External Torx driver or socket that fits around it to drive it.
The sizing for External Torx drivers is different than regular Torx drivers. External Torx drivers use the letter E with a number after it. E4 is the smallest size with E44 being the largest.
The numbering does not match between T for normal Torx drivers and E for External.
For example, the E40 driver is to big to fit on a T40 Torx bit, but an E8 Torx driver will fit on a T40 Torx bit.
In 1990, the Torx patent was expiring. So the new owner of Camcar Textron, Acument created the Torx Plus. The Torx Plus design is similar to the original but is a little different.
By additional squaring off of the original pointed star design, the Torx Plus was created. This is supposed to create more contact between the driver and the screw. This makes it possible to use more torque with less wear and tear on the driver and screw.
By the way an Internal Plus is another name for the Torx Plus. Torx Plus drivers use the letters IP or TP with a number before or after it for sizing. The smallest Torx Plus size is the IP1 or 1IP, with the largest size being the IP100 or 100IP.
Then Textron created the Tamper Resistant Torx Plus. Instead of 6 square points like the Torx Plus, the Tamper Resistant Torx Plus has only five.
Just like a Security Torx, a Tamper Resistant Torx Plus driver has a hole in the middle while a Tamper Resistant Torx Plus screw has a raised pin in the middle of the star pattern.
The Tamper Resistant Torx Plus design with the 5 square points and center raised pin is extremely effective for added security.
It’s nearly impossible to remove a Tamper Resistant Torx Plus screw without the correct Tamper Resistant Torx Plus driver.
Incidentally for even more added security, only original equipment manufacturers (OEM) and authorized service personnel can obtain Tamper Resistant t8 torx security bit screwdriver drivers and screws.
Tamper Resistant Torx Plus use the letters TS or IPR with a number after it for sizing.
Later Textron modified the Torx design again in 2005 and created the Torx TTAP. It’s really a reverse of the Tamper Resistant Torx Plus but with 6 square points.
The Torx TTAP driver has 6 square points and also a pin or round point connected to the tip of the driver that sets in a TTAP screw.
This added feature allows the user to minimize wobbling and keep the driver in the screw without needing a bit with a magnetic tip.
For this reason certain fields are beneficial for TTAP screws.
Also, TTAP drivers can’t be used with normal Torx screws. However, normal Torx drivers can be used with TTAP screws because of the extended tip.
