F436 washers or F436 washers are also called high strength structural washers and ASTM F436 washers used in structural steel connections. F436 washers are thin with a full diameter and are used on A-325 hex bolts, A490 hex bolts and A325 tension controlled bolts and A490 tension controlled bolts. These washers range in diameter from 1/4″ to a” and are manufactured from medium carbon alloy steel that is cooled and tempered to develop the desired mechanical properties.

Description The F436 washer has similar dimensions to the USS flat washer but with a smaller outside diameter. It is produced with high strength grade steel and heat treatment.
Application Designed for use with A325 and A490 structural bolts.
Material They are fabricated from steel that meets the following requirements: Phosphorus- 0.050%; Sulfide- 0.060%.
Hardness Rockwell C38-45
Coating They are usually manufactured uncoated or hot-dip galvanized.
  ASTM F436 covers the chemical and mechanical requirements for hardened washers or washers in diameters ranging from 1/4" to 4" diameter. These heat-treated washers are for general purpose and structural use and are suitable for use with A325 and A490 structural bolts.
