Lindström’s  RX7890 Chain Nose Pliers are precision tools for general use. Smooth jaws are 0.79” long and taper down from 0.238” to 0.030”. Lindström uses 1% carbon/chrome ball-bearing-grade steel in manufacturing their top-of-the-line Rx series Pliers. Computer controlled grinding of forged blanks guarantees accuracy and precise jaw alignment which increases tool reliability and consistency. Precision induction hardening provides high Rockwell hardness (42-46HRC) without brittleness, increasing tool life. Like all Rx Series Lindström pliers, ESD-safe grips are slightly rounded and wide for optimal surface distribution and contact. Rx pliers also feature Lindström’s exclusive, patent pending BioSpring that keeps its tension minimal and limited throughout its range of compression. Spring tension is also adjustable, and the spring is removable.
