This selected size is specified with diameter 9/16 in, length 2 in, thread 9/16 in.
Sold in multiples of '50 pieces. 1 Box = '50 pieces.
Material, Grade & Strength
SAE Grade 5 is a medium to high tensile imperial fastener grade used where greater strength than low carbon steel is required. Use compatible imperial nuts and washers of suitable strength.

Plain finish has no plated corrosion protection and is best used in protected, oiled, painted or indoor environments.
Typical Uses
Imperial UNF and UNC fasteners are used in equipment, vehicles and machinery designed around inch-series thread systems.
Technical Tips
