Security Screws

Security screws are screws with unique heads that make them difficult to remove or tamper with. They are also known as tamper-proof, anti-tamper, or anti-theft screws.
Security screws are used in many industries, including: Aerospace, Automotive, Hospitals and medicine, Correctional facilities, Schools and universities, Military, Retail outlets, Utility companies, Marine, and Transport providers.

One Way Screw	One Way Screw Also referred to as irreversible or one direction screw, this fastener features a slotted drive that is designed to turn in one direction only; when turned in the opposite direction (to unfasten), these screws will cam out. This type of tamper proof screw is manufactured so the sections of the driver are gradually raised to only engage the bit clockwise for fastening; if turned to the left the bit will be rejected and the driver slips out. Though a one way screw can installed with a standard flat blade, they require special driver to unfasten. One way screws are particularly difficult to remove, so they should only be used in permanent applications.
Spanner Screws	Spanner Screws Also known as snake eye or pig nose screws, spanner screws are easily identified by their two dot driver. Offering extreme security, this unconventional screw can only be removed using a spanner driver which features two pins that fit the snake eye holes. Most commonly available in a pan head and flat head screw
Phillips Pin Security Screws	Phillips Pin Security Screws This basic security screw features an added pin to the, preventing them from being removed with a normal phillips drive bit.
Torx Pin Screws	Torx Pin Screws These screws feature the same 6 lobe design as a normal torx screw, but with a central pin, preventing the use of a typical torx bit for added security. The main advantage of a torx pin screw is that they offer slightly higher torque than a hex pin. Similar to the torx pin, the 5-lobe pin screws have a 5 star (verses 6 star of the tox) driver. These tamper resistant screws offer higher lever of security than the 6-lobe pin torx screws because the driver is less common. In addition, they provide a higher torque capacity.
Hex Pin / Socket Security Screws	Hex Pin / Socket Security Screws One of the original security screws, hex pins (socket security screws) use a common socket driver with a center pin for improved tamper resistance. This pin prevents attempts at unfastening using a flat-blade driver and provides slightly higher torque as well as resistance to cam out and tool wear compared to a conventional socket drive. As they are not as complicated to manufacture, they can be offered in smaller sizes and more diverse materials. Most commonly available in flat and button head style screws.
External Pentagon Bolts	External Pentagon Bolts Also called a penta bolt, these screws provide the same advantages of a standard hex head bolt – wide fastening surface area – but with the added value of an unconventional driver for tamper resistance. Pentagon bolts require a specific pentagon socket that is not often found in retail stores, though they can be tampered with using common items such as locking pliers. Pentagon bolts are ideal when larger size fasteners are needed.
Tri-Groove	Tri-Groove This unique round head with three side grooves provides high security. Tri groove screws are difficult to grab with standard pliers and require a special socket driver. When proper installation tools are used, this screw offers considerable torque with low fastener distortion and little breakage.
Tri-Wing	Tri-Wing Tri-drive screws are commonly used on high volume, low security risk applications. This design features a triangle drilled center with three wings. Unlike a tri-point screw which has three wings that intersect in the center, the wings of this screw are off-set. Another version of a tri-wing that is common is called an Opsit® tri-drive, which features a left-handed threads. An Opsit screw can only be removed by turning it clockwise. These are common in aviation and aerospace fasteners.
