20% TOUGHER TO REMOVE THAN LOCK WASHERS
Washers of any kind should never be used with security screws.
Raptor™ Button Heads and Flat Heads are instant security options that can be added to many of our fasteners. They feature oversized heads with specially designed serrations on the underside that grip and eliminate the need for a washer.
Washers are bad for security. Be aware, using washers of any kind with security screws decreases the security. Washers raise the side walls of fastener heads allowing room for wrenches to grip and tamper or remove.
Sizing for Raptor™ Button Head begins at 6/32(M3) to 5/8-11(M16) Raptor™ Flat Head begins at ¼-20 (M6) and goes to 5/8-11(M16).
Raptor™ Button Heads are made with larger diameter heads. The serrations spread the load and grip 15-20% better than regular button head screws. The bigger Raptor™ Head allows a bigger diameter driver, giving a higher than normal torque.
Raptor™ Button Heads work well on high tensile applications such as bridges. They’re exceptional in fencing, security bars, metal buildings, hurricane protection, vacated properties, public utility junction boxes, manhole covers, and custom High-Security applications.
Raptor™ Flat Heads are made with larger diameter heads. The serrations spread the load and grip better than regular flat head screws. Our Raptor™ Flat Head has earned a patent because the serrations can cut deep into the substrate, doubling the required removal torque. They can easily replace “break-off” screws used in security sensitive applications such as prisons. They’re harder to remove, less expensive, and easier to install.
Raptor™ Flat Heads work well on high tensile applications such as bridges. They’re exceptional in fencing, security bars, metal buildings, hurricane protection, vacated properties, public utility junction boxes, manhole covers, custom High-Security applications, or any "break-off" security screw application.
