Whenever there is a need for using fixings in a public place, there is also the opportunity for some to mess with them – no matter if it is casual vandalism or a premeditated act.
With that in mind, engineers developed several types of tamper-proof security screws to hinder partially or prevent fully the possibilities of interference with these fixtures.
Keep reading to find out more about the most widely used tamper-proof screws today:
Pin Hex Head Screws
While conventional socket screws feature a hexagonal recess and need an Allen key or a hex bit to be fixed, Pin Hex screws also use a similar drive. The main difference is the pin inserted in the middle, which requires a unique tool for fixing or removing them. That pin is what stops a normal hex bit from working in these cases.
Pin TX screws
As seen above in the Pin Hex, the Pin TX also features an inserted pin in the drive recess. The difference here is the type of recess, which is a Six Lobe or a Torx drive. Such screws need a particular tool for fixing or removing them.
These screws feature a unique drive design, which can be turned one way only. They are fixed using a simple Crosshead or Pozi driver. This is a one-way fixing solution for extensive use.
Sentinel screws, a superior one-way screw for large volume applications due to its drive, and clutch head screws are similar to Sentinel Screws because they are able to be fixed with a normal tool – here we talk about a simple slotted screwdriver. However, once fitted, this screw cannot be unscrewed, which makes it ideal for permanent fixing needs.
Two Hole Screws
Also known as Pig Hole screws, they feature two holes in the screw head, which makes them look like a pig nose. These two holes require a special bit for screw fixing. These screws are used where there is a concern for aesthetics.
In general, security screws can be used as a simple replacement for normal screws. You can find a large stock at Fastenright featuring a full range of tamper-proof security screws. Most of our products are finished using A2 stainless steel and offer low to medium levels of security resistance.
Using Tamper Proof Security Screws On Products
Security screws are a valid consideration for more than preventing theft. Manufacturers can take advantage of them to prevent product tampering.
It is common enough to see a variation of a legal message on the product or within instruction manuals: “Don’t take apart the product, refer to the service authorized assistance or to a qualified professional.” This is especially true in regards to electrical products, where the user would be exposed to an electrical shock. In that case, using security screws is a great deterrent because it creates an extra obstacle to the product being taken apart by the end-user.
Another alternative use of security screws is by furniture manufacturers who may prefer to avoid having the furniture being taken apart after the manufacture, assembly, and delivery to the customer’s house. Perhaps it is complicated to assemble it once again, and it would require professional help, or the disassembly might compromise the customer’s safety. Using security screws is a simple way to prevent amateurs from tampering with the furniture.
Finally, tamper-proof security screws might be useful if you want to become the only option for product repair and maintenance. In this scenario, users would not be able to fix the product by themselves unless they damage the outside box, so it is good prevention to avoid having curious customers from causing further damage to internal mechanisms when trying to fix the issues.
Premium Security Screws
If you have a higher need for security, then you should go for the premium option. These Tricone Security Bolts feature a drive design that is more complex and can only be installed or removed using a specialist tool that is traceable.
The Security Bolt is unique to Fastenright. Its patented drive design makes it virtually impossible for unauthorized users to remove these bolts. Plus, they look good as well!
Choosing Tamper Proof Screws
These are the criteria you should follow to select the best tamper-proof screws for your needs:
- How much security are you looking for?
- Will the screw have to be removed?
- How much torque fixing is required? (For example, a Pin Hex screw could be more indicated than a Two Hole)
- Do you have aesthetic appearance concerns?
There is an extensive range of tamper-proof screws you can buy as machine screws if you have pre-tapped holes, and self-tapping screws which do not require existing holes.
