Professional Applications & Engineering Value
These zinc-plated steel flat washers deliver critical engineering solutions for industrial assembly challenges. The corrosion-resistant zinc coating prevents galvanic reaction and extends component life in humid or chemically aggressive environments. With precise 0.156" inner diameter and 0.562" outer diameter dimensions, these flat washers ensure perfect alignment with No. 6 screws, preventing loosening from vibration while distributing clamping force evenly across surfaces. The Rockwell B40 hardness provides optimal balance between durability and flexibility, making them ideal for electrical enclosures, machinery assembly, automotive components, and construction applications where reliable fastening is paramount.
