5 Common Tamper-Resistant Screw Drives

Screw drives that require special tools to torque into place or to unfasten are considered to be tamper resistant. They also tend to be fairly rarely used. These drives are ideal for applications ranging from aerospace technology to video game consoles, because they inhibit tampering or unsupervised repairs. Each of the five drives listed below are considered tamper resistant, but not tamper proof, given the availability of screw driver bits on the market.  For a tamper proof screw installation, … Read more

Design Benefits of Thermoplastics in Pump and Valve Components

Thermoplastic components strengthen pumps and valves through resistance to corrosion, lower repair costs and extended service lives, which is why operators are choosing plastics over metal parts. There are many more advantages to using plastics, including decreased vibration and higher temperature thresholds that enhance operational efficiency. Ultimately, all of the thermoplastic design benefits equate to cost-savings and greater reliability in the field.

Temperature Resistance
Thermoplastics have less thermal conductivity compared to metal components, which is beneficial for preventing damage to pumps and valves exposed to high internal and external temperatures. … Read more
