DIN 434:2024 Washer

DIN 434:2024 Square Taper Washer for channel sections is used at sloped bearing surfaces such as channel flanges. The tapered structure compensates for the angle of the channel surface, allowing the nut or bolt head to seat more evenly and reducing eccentric loading.

It is suitable for steel-structure installation, support systems, bridge accessories, equipment bases, and structural-section connections. By correcting the bearing angle, the square taper washer improves bolt load distribution and protects the surface of the steel section.

The corresponding model and surface treatment can be selected according to channel size, bolt dimension, and corrosion-protection requirement, making it suitable for indoor and outdoor steel fastening and repair reinforcement.
