The Pitsco 36460 TETRIX Tank Tread Chain Links are polyoxymethylene (POM), and can be used to build up to 3-1/4 feet of tank tread or conveyor belts for students in grades 9-12 building TETRIX robotics projects. The chain links are made of durable POM (also known as acetal copolymer plastic), which has high tensile and flexural strength, is hard, and fatigue resistant. The chain links snap together for user ease and can be separated for reuse in other projects. The chain links come in packages of 100, and they each measure 8mm x 40mm (W x D). (W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.) TETRIX products reinforce science, technology, engineering, and mathematics (STEM) concepts for students in grades 9-12 studying robotics and building a working robot that demonstrates engineering, simple machines, force, and Newton's laws of motion. Tank tread chain links can be used in an educational setting to build a robot, among other mechanical robotic applications.

Science education products incorporate applied math and science principles into classroom and homeschool-based projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology.

Pitsco Education develops K-12 science, technology, engineering, and math (STEM) curriculum, educational kits, and classroom tools. The company, founded in 1971, is headquartered in Pittsburg, KS.
