Security Screws

Custom and Tamper-Resistant Security Screws

Pattern Fasteners manufactures standard, special and custom security screws for applications where conventional fasteners do not provide sufficient protection against unauthorised removal or interference.

Security screws use specialist head or drive profiles that make them more difficult to remove with conventional tools. They are widely used for access panels, equipment, machinery, public infrastructure and other assemblies where tamper resistance and controlled access are important.

We manufacture security screws to customer drawings, existing samples and bespoke specifications, with options for specialist drive types, non-standard dimensions, materials, finishes and mechanical properties.

Security Screw Drive Types

The drive design is one of the most important features of a security screw.

Depending on the level of access control required, security screws can incorporate drive profiles that require a matching specialist tool for installation or removal.

Options may include:

• Pin-in hex drives

• Pin-in six-lobe drives

• Two-hole or spanner drives

• One-way drive designs

• Triangular drives

• Specialist socket profiles

• Customer-specific drive designs

• Bespoke recessed profiles

The most appropriate option will depend on whether the fastener needs to be removable for authorised maintenance or is intended to discourage routine removal.

Custom and Non-Standard Security Screws

Many security applications require more than a specialist drive profile.

Pattern Fasteners can manufacture security screws with dimensions and features tailored to the individual assembly, including:

• Metric and imperial threads

• Standard and non-standard diameters

• Coarse and fine thread pitches

• Bespoke overall lengths

• Fully or partially threaded designs

• Custom head forms

• Recessed or low-profile heads

• Specialist drive recesses

• Custom point styles

• Drilled or modified features

• Heat treatment and controlled hardness

• Small batches and repeat production quantities

Components can be manufactured from your technical drawing, existing sample or application requirements.

Bespoke Security Drive Profiles

For applications requiring a less common fastening solution, bespoke or customer-specific drive features can also be considered.

This can be useful where standard security screw profiles are unsuitable or where a specific component design requires a unique head or recess geometry.

Our team can review the required dimensions, tooling considerations and production quantities to determine the most appropriate manufacturing route.

Materials and Finishes

Security screws can be manufactured in a wide range of materials to suit the required strength, corrosion resistance and operating environment.

Options may include:

• Carbon steel

• Alloy steel

• Stainless steel

• Brass

• Aluminium

• Titanium

• Specialist and non-ferrous alloys

Protective and decorative finishes can also be incorporated into the specification, including:

• Bright zinc plating

• Chemical black

• Phosphate coating

• Tin plating

• Chrome plating

• Customer-specified coatings and treatments

Heat treatment and specified hardness can also be incorporated where required.

Applications for Security Screws

Custom security screws are suitable for applications where unauthorised access, vandalism or component removal needs to be discouraged.

Typical applications include:

• Access panels

• Electrical enclosures

• Machinery and industrial equipment

• Public infrastructure

• Transport equipment

• Security equipment

• Protective housings

• Retail fixtures and displays

• Street furniture

• Automotive assemblies

• Defence and specialist engineering

• Vandal-resistant installations

Removable or One-Way Security Fasteners

Not every security application has the same maintenance requirements.

Some assemblies need to remain accessible to authorised engineers, making a removable security drive the preferred option. Other applications may require a fastener designed to make subsequent removal considerably more difficult.

Our team can review the application and help determine an appropriate drive style and fastener design.
