Bright Zinc Plated Steel, Flange Bolt, M5mm x 20mm

The RS Pro Flange bolts feature a serrated flange under the hexagon head, acting as a built-in washer for faster installation, especially on production lines. As they're tightened, the serrations grip the mating surface, ensuring a secure connection by spreading the load over a larger area. Fully threaded, they're inserted directly into tapped holes without requiring a nut, while part threaded ones are secured with a nut on the protruding thread. The hexagon head allows for easy tightening and loosening using a socket drive or spanner. These versatile bolts find application in automotive, machinery, and industrial settings, offering durability and corrosion resistance due to their bright zinc plated finish.
