Various Security Screw Types

When protecting valuable assets, maintaining privacy, or deterring theft, traditional screws and bolts don’t always cut it. In these scenarios, security screws offer a reliable solution. Moreover, security screws are specialised fasteners designed to provide enhanced resistance against tampering and unauthorised access. Whether you’re a business owner, a homeowner, or a DIY enthusiast, understanding security screws and their applications can certainly help fortify your security measures. In this article, we will delve into the world of security screws, exploring their types, features, and common applications. Furthermore, we’ll examine how these innovative fasteners can play a crucial role in bolstering your overall security strategy.


1. What are Security Screws?

Security screws are also known as tamper-resistant screws. They are fasteners engineered to prevent unauthorised removal or tampering. Unlike standard screws, security screws incorporate unique design features that make them difficult to remove without specialised tools. These features provide an added layer of protection, reducing the risk of theft, vandalism, or tampering.


2. Types of Security Fasteners

a) Pentaforce Screws: Pentaforce Screws feature a pentagon shape drive head with a small pin in the centre, rendering them virtually impossible to unscrew with regular tools. To remove these screws, a matching driver or tool with a hole or groove to fit the pin is required.

b) Two Hole Screws: Two Hole Screws, also known as snake-eye screws, have a unique head design with two small holes instead of a traditional screwdriver slot. These screws require a special two-pin driver to install or remove.

c) Resytork Screws: Resytork Screws utilise a six-point star-shaped head, known as a Torx drive, which requires a matching Torx driver or bit for installation or removal. The multiple points of contact offer increased torque transfer, reducing the risk of the screw slipping or stripping.

d) One-Way Screws: One-Way Screws such a Clutch Head Screws, are designed to only be installed, not removed. These screws have a slotted drive on one side, while the other side features a smooth, round head with no grooves or slots. Once tightened, the one-way screw cannot be easily removed using conventional tools.

e) Custom Screws: Custom Screws such as the Uni-Set or Four-Hole Screw features a unique drive design pattern with no two the same. To install or remove these screws, a unique, specialised driver that fits into the hole pattern is required. The unique driver provides the necessary torque for tightening or loosening the screw.


3. Applications of Security Fasteners

a) Commercial and Retail: Security screws find widespread use in commercial and retail settings. They secure cash registers, safes, displays, and cabinets. They also help deter theft and unauthorised access to valuable items or confidential information.

b) Public Infrastructure: Security fasteners can play a vital role in securing public infrastructure such as traffic signs, utility meters, access panels, and public furniture. They prevent tampering, vandalism, and unauthorised dismantling.

c) Residential Security: Homeowners can utilise security fasteners to fortify their doors, windows, alarm systems, and outdoor fixtures. By using tamper-resistant fasteners, homeowners can enhance the security of their property and protect against break-ins.

d) Automotive Industry: Security fasteners are utilised in the automotive industry to secure license plates, mirrors, badges, and various components. They act as a deterrent against theft or unauthorised removal of valuable automotive parts.

e) Electronics and IT Equipment: Many electronic devices and IT equipment incorporate security screws to prevent tampering or unauthorised access to sensitive data. They are commonly used in computer cases, gaming consoles, routers, and medical equipment.

f) Manufacturing: Many appliances and machinery incorporate security screws to protect sensitive components from tampering or unauthorised repairs. This helps safeguard intellectual property and ensures product integrity.

g) Government and Military Applications: Government agencies and military organisations extensively use security screws to protect classified information, secure equipment, and prevent unauthorised access to critical areas.


4. Advantages of Security Screws

a) Deterrence: Security screws act as a visual deterrent, discouraging unauthorised individuals from attempting tampering or theft.

b) Increased Security: With specialised drive designs, security screws provide an additional layer of security, making it difficult for casual tampering or removal.

c) Customisation: Various types of security fasteners are available, allowing organisations to choose the most suitable option for their specific needs.

d) Accessibility Control: Security screws limit access to sensitive areas, ensuring that only authorised individuals can access vital equipment or infrastructure.



Security fasteners are an essential component of comprehensive security systems. Additionally, by utilising tamper-resistant fasteners, individuals and businesses can enhance protection against theft, vandalism, or unauthorised access. Moreover, the wide variety of security screw types ensures that there is an appropriate solution for every application. Whether securing valuable assets, maintaining privacy, or preventing tampering, security screws provide an effective and reliable means of protection. Furthermore, understanding the different types, features, and applications of security screws empowers individuals to make informed choices when it comes to defending their assets and maintain security.
