Professional Applications & Engineering Value

This hard fiber flat washer delivers critical engineering solutions where electrical insulation and corrosion resistance are paramount. The gray hard fiber material provides exceptional dielectric properties, making it ideal for electrical enclosures, control panels, and electronic assemblies where metallic washers could cause short circuits. With a maximum temperature tolerance of 230°F, it maintains structural integrity in heated industrial environments while the precise 0.75" ID ensures perfect alignment with 3/4" screws. The fiber composition naturally resists galvanic corrosion when used with dissimilar metals, eliminating the need for additional coatings or treatments. These flat washers serve as reliable spacers and load distributors in plumbing, automotive, and machinery applications where non-conductive, chemically resistant components are essential for long-term performance.

Specification Summary & Compliance

This inch-system flat washer features precise dimensional specifications: 0.75" inner diameter, 1" outer diameter, and thickness ranging 0.014-0.016". Manufactured from hard fiber material in gray coloration, it's engineered for use with 3/4" screw size fasteners. The product fully complies with RoHS 3 (2015/863/EU) restrictions on hazardous substances and meets REACH (EC 1907/2006) requirements regarding chemical substances of very high concern. While hardness is not rated, the fiber construction provides consistent performance across industrial temperature ranges up to 230°F maximum.
