5-Lobe Button Head Security Screws
Designed for high security applications where tamper resistance is essential, these button head security screws feature a low profile rounded head that provides a neat finished appearance while reducing the risk of snagging or interference. The unique five lobe drive with central pin prevents unauthorised removal and offers a higher level of protection than Pin-Torx or Pin-Hex alternatives. Manufactured from corrosion resistant A4-70 stainless steel, they are suitable for demanding indoor and outdoor environments.
The button head profile is ideal where a smooth surface finish is required without the need for countersinking. This makes these fasteners particularly well suited to public facing installations where appearance safety and tamper resistance are equally important. Available as self tapping screws or metric machine screws, they provide flexible installation options across a wide range of materials and assemblies.
These button head security screws are widely used across public infrastructure automotive electronics and retail environments where discreet high security fixing is required while maintaining a professional appearance.
What are the benefits of A4 stainless steel?
A4 stainless steel contains molybdenum which significantly improves resistance to corrosion particularly in salty humid or industrial conditions. This makes it ideal for outdoor installations marine environments and applications where long term durability is critical. A4 stainless steel offers a higher level of protection than A2 stainless steel which is more commonly used but less resilient in aggressive conditions.
Why is a 5 Lobe drive more secure than Pin Hex or Pin Torx?
Our five lobe fasteners are rated at Security Level 2 Enhanced Security while Pin Hex and Pin Torx fasteners are rated at Security Level 1 Entry Level Security.
The five lobe drive pattern is intentionally uncommon which makes it difficult to engage using standard tools found in most toolkits. Unlike hex or Torx drives which are widely available the five lobe design adds an additional layer of protection against tampering and unauthorised removal.
Please note that to protect the integrity of our security fasteners the relevant installation tooling is not available online.
Tooling is supplied by request and only to registered businesses.
