Types of Security Screw

The security screws produced by our company mainly include the following types:

 
 

One Way Screws

One way screws, also known as irreversible screws, are a very unique drive style which ensures that it can only be driven out in the driver moving in one direction. If the driver moves the head in an incorrect direction, the screw will instantly cam. To achieve this, the drives are manufactured in quadrants to accept the driver’s momentum if moved in the right direction.

 
 
 

Spanner Security Screws

The spanner security screw is also known as the “Snake Eye” due to its elegant and snake-like groove on the head. The corresponding drill bit required is also unique and should ideally come with the two-dot drive system. Spanner security screws are manufactured to protect public installations that need to be constantly removed and therefore not required to be protected by the one-way screws.

 
 
 

Torx Security Screws

Torx is a very special security screw that comes with 6 lobes and pin which need to be driven with security bits to ensure safe and smooth installation and removal of the fastener. These screws are characterised by the standard 6 lobes or stardrive and a central pin. The biggest advantage of Torx screws is that, in addition to the lobes providing tamper-resistance, the pin provides another dimension to security.

 

 

Advantages of Security Screw
 

Enhanced Security

Security screws are designed to prevent unauthorized access and tampering, featuring unique configurations that require specialized tools for installation and removal. This enhanced security is crucial in safeguarding assets and installations across various industries.

Theft and Vandalism Deterrence

Security screws reduce the risk of theft and vandalism by being challenging to remove without proper tools, discouraging unauthorized disassembly or theft of valuable items. This is particularly beneficial in public spaces, retail environments, and other areas where high-value assets are at risk.

Increased Safety

These screws ensure critical components and equipment stay securely fastened, reducing the risk of accidents or malfunctions. In environments where safety is paramount, such as industrial settings or public infrastructure, the use of security screws can prevent potential hazards and maintain operational integrity.

Counterfeit Prevention

The use of unique and specialized fasteners like security screws can help prevent counterfeiting. These screws make it more difficult for counterfeiters to replicate or imitate products, thus protecting brand reputation and ensuring product integrity. This is particularly important in industries such as electronics, pharmaceuticals, and consumer goods.

Warranty Protection

Security screws help maintain the validity of warranties or guarantee seals. By ensuring that products remain sealed and intact, these screws provide clear evidence of non-tampering, which is essential for upholding warranty conditions. This can be particularly important for manufacturers and consumers alike, offering assurance that the products have not been compromised.

Peace of Mind

Using security screws provides peace of mind by safeguarding assets, products, and equipment against unauthorized access, allowing stakeholders to focus on other important operations. This added layer of security ensures that valuable resources are protected, contributing to overall operational stability.

Material of Safety Screw
 

Aluminum

Silvery-white in color, this common metal is lightweight and non-magnetic. It is soft, ductile, and has a high corrosion rate in the proximity of acids or alkaline.

Steel

Steels are produced differently, depending on their purpose. They are broadly categorized into four groups: carbon steels, alloy steels, stainless steels, and tool steels. In general, steel is relatively corrosion resistant. It's three times heavier than aluminum, common, tough, strong, durable, malleable, and silver in color.

Copper

Pinkish/brownish in color, ductile, soft, malleable, and very high in thermal and electrical conductivity.

Brass

As this is an alloy of copper, it has similar properties, like being soft, a good conductor of heat, and malleable. It is also resistant to corrosion and non-magnetic.

Monel

Excellent corrosion resistance in many environments such as saltwater. However, it is susceptible to galvanic corrosion, meaning if aluminum, zinc, or iron are used around it, it can quickly corrode. It is high in strength and uncommon.

Titanium

Very high corrosion and thermal resistant. It is lightweight, low density, and very tough. It is rare and quite expensive, also suitable for use in medical instruments and devices.

 

Precautions for Using Safety Screws
 

Choose the Right Security Screw Type
There are various types of security screws available on the market, each with its unique features and installation requirements. The most common types include Pin Hex, one-way Clutch Head Screws, tamper-resistant Pentaforce, and Two Hole Screws.

 

Invest in Quality Screws and Tools
To ensure the integrity and effectiveness of security screws, it is crucial to invest in high-quality screws and appropriate tools. Cheap or inferior quality screws may strip or break, rendering them ineffective. Likewise, using incorrect or worn-out tools can damage the screw head, making it difficult to install or remove the screws when necessary.

 

Prepare the Installation Surface
Before installing security screws, it is essential to prepare the installation surface appropriately. Ensure that the surface is clean, free from debris, and suitable for screw penetration. Clear away any dust, dirt, or obstructions that could hinder the screws’ installation or compromise their effectiveness.

 

Use the Right Tools
To install security screws properly, you will need the right tools. Typically, a compatible screwdriver or drill bit designed specifically for the type of security screw you are using is required. Investing in a high-quality tool will ensure proper engagement with the screw head, minimising the risk of stripping or damaging the fastener during installation.

 

Apply Adequate Torque
Security screws are designed to be resistant to tampering and removal, so applying adequate torque during installation is essential. Avoid using excessive force, as it may strip the screw or damage the surrounding material. Applying too little pressure can result in an incomplete installation, compromising the screw’s security.

 

Protect the Screw Heads
Since security screws are specifically designed to deter tampering, it is important to protect the screw heads from external elements. Consider using tamper-resistant covers or caps like Armour Rings or No Go Security Enclosures that provide an additional layer of security by concealing the screw heads.

 

Consider Tamper-Resistant Anchors and Fasteners
In addition to using security screws, consider tamper-resistant anchors and fasteners. Tamper-resistant anchors and fasteners come in various forms, including Shear Nuts, Sleeve Anchors, and tamper proof Screw Bolts. Incorporating these devices into your installation can enhance security measures.

 

Maintain a Safe and Secure Storage of Tools
Considering that security screws require specialised tools for fitting, it is vital to store these tools securely. Moreover, misplacing or leaving tools unattended can lead to unauthorised access or tampering. Therefore, maintain a proper inventory of the tools, store them in a secure location, and ensure only authorised individuals have access to them.

FAQ

 

Q: How does a security screw work?

A: Security screws are purposefully designed screws for protecting materials and other items from being tampered with. They feature a unique head, making it incredibly difficult for an end-user to remove them without the right equipment.

Q: How do you deal with security screws?

A: The simplest solution is using a screw extraction kit. Since you know the size and threading, once you drill and exact the security screws, you simply replace them with the appropriate sized non security screws. Or you know, use new security screws if you need that extra bit of annoyance.

Q: What tool to use for security screws?

A: Taking out screws with a special security feature needs a hex wrench with a hole made for the pin. Tri-Groove Tamper Proof Nuts: Our Tri-Groove security nuts feature a tapered design with specialized indentations that require a matched Tri-Groove socket tool to grip and install.

Q: Why do security screws exist?

A: Security bolts and screws are designed with unique features that are intended to prevent tampering, theft, or unauthorized access. Specialized tools are typically required for installation and removal.

Q: How do you remove a broken security screw?

A: You can use a rotary tool to cut a new slot into the stripped screw to help remove it a little easier. One method to remove a stripped screw requires using a powerful multitool — or rotary tool — fixed with a spinning metal blade.

Q: How do you keep a screw secure?

A: If necessary, use additional locking material on the screw hole to increase friction and ensure your screw is fastened evenly and smoothly. Clean up any excess thread locker glue with a paper towel, and you're set!
