JAPANESE/ENGLISH VERSION
This standard covers the cold-forged steel hexagon-socket-headbolts, mainly used in automobiles (hereinafter referred to as”bolts”).
Note: The bolts of this standard are used where spacerestriction around the hexagon head refuses the tool access to theheads for driving them, such as in the case of sinking a hex headinto a spot faced recess. The bolts of this standard are smaller inthe bearing surface area than their corresponding hexagon headbolts by 30 to 60%, making it difficult to secure axial tensionappropriate for their property class; therefore, they will begradually restricted in use as standard parts and will be used asthe parts for special uses, for which drawings are issued.
