WORLD BIGGEST NUT AND BOLD BY ENGINEERING WORLD
The Scottish business Penrith Engineering Works produced the largest bolt ever in 1967.
They measured 27.4' long (8.3m) by 4.2' in diameter (1.27m) and weighed 12.6 tonnes.
In an effort to enhance the capacity of oil tankers by bolting two of them together, 60 of them were manufactured for SWISSOIL.
These SmartBolts are provided by a mining services firm that replaces bearings in order to make sure the bearings they install are correctly preloaded, to ensure ease of maintenance and a long service life for their clients. Installers can confirm that the critical bearing bolts are correctly tensioned using the visual signal in SmartBolts, and inspectors may quickly visually check to determine if residual bolt tension is still present during service.
