Bridges are among the most load-intensive structures we build, and they require fastening solutions that guarantee long-term strength and safety. Square washers in bridge construction serve a critical role by distributing load and minimizing stress concentrations around bolts and joints. Their wide bearing surface reduces the risk of metal fatigue and improves connection longevity.
These washers are typically used in conjunction with high-tensile bolts and structural steel plates. Their shape prevents rotation, which is essential in applications where shear and torque forces are constant. With corrosion-resistant finishes such as hot-dip galvanization or stainless steel variants, they provide resilience in even the most challenging weather conditions.
