Developed by ITW Shakeproof, BosScrew™ is the only screw specifically designed not to loosen in plastic applications. It will remain secure over time, despite temperature changes and under vibration. BosScrews™ provide as much as four times the holding power and a drive-to-strip ratio 66% better than the leading screws being used in today's plastics. This is not merely a new screw for plastic materials but a new concept in how to achieve a secure fastening in plastics.

Features and Benefits N/A Instead of attempting to compensate for plastic creep, BosScrew™ actually uses that creep to achieve an interlocking embedment of the threads in the material. This unique screw has a series of "pressure wells" or indentations along the upper face of the thread circumference. Once clamp load is applied to the assembly, the plastic creeps into the indentations in the threads creating resistance bumps in the material with valleys in between. To loosen, the crests in the screw thread between the indentations must climb over each of these bumps. Reverse tightening torque must actually be applied to drive the screw back over the bumps and loosen it.
