Security screws are designed for installations where the fasteners are visible to the public, and the installer, manufacturer or owner want to ensure their equipment isn’t tampered with, damaged or removed. In a setting such as a public restroom, tamper proof fasteners are used to mount the stalls to the walls. These fasteners are installed with fastener specific tools. Some of the fasteners have a unique shaped slotted head. A traditional Phillips or straight screwdriver won’t fit into the head, and the fastener is installed and removed by a tool that only a the installation contractor would carry. Other security fasteners have a traditional shaped slotted head, like a Torx or Square drive. These fasteners have a small pin in the middle of the slot. A standard tool won’t fit into the fastener’s head. Installing or removing the fasteners requires a special tool that features a dimple in the tip which allows the tip to fit over the pin. These fasteners are called Pin-Head fasteners.


Security screws are available in several different tool configurations, and in a full size range. Snake eye spanner head fasteners require a special tipped tool for installation and removal. Philips, socket and Torx pin-head fasteners require a tip for a standard drill driver tool that allows the tip to slide into the head of the screw, over a small pin. A one-way slotted head screw inserts with a traditional straight head screwdriver. However, the slot is beveled, and the screwdriver can’t grip the fastener to remove it. These fasteners must be removed with a vice grip locking pliers, or removed with a drill.

mounting a solar panel with a fastener
Specialty, tamper resistant fasteners are available in a full spectrum of steel grades, including stainless steel,and grade 5 hardened steel. These fasteners save property owners thousands of dollars by thwarting equipment vandalism, tampering and physical damage.

Another installation which requires specialty hardware is solar panel mounting systems. Solar panels are mounted in multi-panel arrays, and the individual panels are held to the arrays via custom mounting hardware which grips the backside of the panel.  When mounting a solar panel array, the most important aspect of the solar panel mounting hardware is the stability of the entire system. Solar panels which are mounted to the ground are typically mounted on top of a pole which is cemented into the ground.

The pole should be at least 36 inches into the ground, in a hole that is 12 inches in diameter. After the pole sets in the concrete, a rigid and corrosion resistant grid is mounted to the pole that looks like a large checker board. The panels are fastened to the support arms, and are angled toward the sun to receive the maximum sun’s rays.

When solar panels are mounted to a building’s roof, specialty fasteners are also required. Solar panels should be installed so that they are firmly attached to the roofing system yet at the same time removable for maintenance and replacement. For new buildings, specialty fasteners are recommended which fasten the metal roofing systems to the building’s framework and at the same time provide the studs to which the solar panels mount. When designing a solar panel installation, make sure to research the installation options ahead of time.  A proper installation requires the right fastener and proper preparation and planning.
