Security Screws with Pin In Drives

Security Screws

Security Screws are currently available only in Stainless Steel, Stock Styles are: Machine Screws, Self-Drilling Screws and Self-Tapping Screws. Many more sizes and styles coming soon!

Types of Tamper-Resistant Security Screws

Fastener Superstore currently offers wholesale security screws in three tamper-resistant drive styles. 3 wing drive screws use a unique three-slot recess that needs a matching bit, making them a solid choice when you want a noticeable step up from standard drives. 6 lobe with pin screws add a center pin inside the 6-lobe recess, which blocks regular drivers and requires a compatible security bit for installation and removal. Hex drive with pin screws work the same way, using a center pin to prevent standard hex keys from engaging.

You’ll find these drive styles across common screw types so you can match the fastener to the material and installation method. Choose machine screws when you’re threading into a tapped hole or using a nut, self-tapping screws when you need to cut threads into pre-drilled material, and self-drilling screws when you want to drill and fasten in one step. That way you get the tamper resistance you need without compromising fit, holding power, or install speed.

Why Use Tamper-Resistant Security Screws?

Tamper-resistant screws, along with tamper-proof nuts, help protect equipment, property, and public spaces by making casual removal much harder. They’re a practical fit for areas that see frequent contact, like restrooms, stairwells, parks, and exterior enclosures. When standard fasteners get removed, it can lead to safety issues, downtime, or replacement costs that add up fast. Tamper-proof screws reduce that risk without creating a complicated installation process. Authorized teams can keep the correct drive bits on hand, while the general public cannot. For facilities teams, that means fewer missing panels and fewer exposed electrical boxes. They also support consistent upkeep, since access is controlled instead of improvised. When theft prevention is a priority, these fasteners add a simple, effective layer of deterrence without changing the design.

Benefits of Using Security Screws

Security screws are not meant to make removal impossible. They make unauthorized removal difficult enough to deter most tampering. That barrier helps prevent damage, reduces nuisance access, and keeps panels where they belong. When installed to spec, anti-tamper screws hold steady torque and clamp load, so covers, guards, and access doors stay tight through vibration and daily use. Since current stock is stainless steel, they fit wet, washdown, and outdoor areas where corrosion and appearance both matter. They also cut maintenance time because staff are not constantly re-securing loosened hardware or replacing stripped heads from the wrong bit. For safety programs and audits, security fasteners help keep protective components in place between scheduled inspections and service intervals. Standardizing one drive style simplifies inventory and training.

Industrial and Commercial Uses for Security Fasteners

In commercial and industrial settings, security fasteners show up anywhere access needs to be controlled without changing the entire design. Common use cases include electrical enclosures, HVAC panels, elevator controls, restroom partitions, signage, and street furniture. They’re also used for public kiosks, telecom boxes, and school or campus equipment where tampering is a recurring issue. Security drives can be applied across different substrates, including sheet metal housings and brackets. Many teams standardize one drive style across a facility so maintenance stays simple. They’re useful for access doors, control cabinets, junction boxes, machine guards, and protective covers where loose hardware creates safety or compliance risks. For projects that repeat across sites, ordering bulk security screws helps keep installs consistent, reduces downtime, and makes reordering straightforward for each work order.

Frequently Asked Questions:

What are security screws?

Security screws are screws designed with a tamper-resistant drive that can’t be removed easily using standard bits. They’re used to discourage unauthorized access, vandalism, or theft. Many applications pair them with other tamper-proof fasteners to secure panels, covers, and public-facing hardware.

What types of security screws are available?

Common options include machine screws, self-tapping screws, and self-drilling screws, each available with specialty drive styles. The best choice depends on the substrate and whether you’re fastening into a threaded hole, forming threads in metal, or drilling through thin material during installation.

What are tamper-resistant drive styles?

Tamper-resistant drive styles are head designs that require a matching bit not found in typical tool kits. Examples include pin-in drives and other specialty recesses. These designs make removal difficult without the correct driver, which discourages casual tampering.

Where are security screws commonly used?

They are commonly used in public and semi-public environments like schools, parks, restrooms, transit areas, and storefront exteriors. In industrial settings, tamper-proof screws are used on equipment guards, access panels, enclosures, and controls where unauthorized removal could create safety or operational problems.

Are security screws corrosion-resistant?

Current security screws are offered in stainless steel, which provides strong corrosion resistance for many indoor and outdoor environments. For harsher exposure, matching the grade and finish to the conditions is still important, especially near salt, chemicals, or persistent moisture, to keep performance consistent.
