JAPANESE/ENGLISH VERSION
この規格は,主として自動車に使用する鋼製の冷間圧造で,かつISC-A00-008Yに適合する六角ボルト(以下,ボルトという。)について規定する。
注記1M4はISD-C03-500Y(十字穴付き小ねじ),M5はISD-C03-503Y(ヘクサロビュラ穴付き小ねじ)を使用すること。
注記2焼きもどし温度が低いボロン鋼を採用しているため,200℃以上の部位に使用する場合は締結軸力の低下,材料強度の低下に留意すること。
This standard covers steel hexagon bolts formed by cold forging,in compliance with ISC-A00-008Y for general use in automobiles(hereinafter referred to as “bolts”).
Notes 1. For the bolts of M4 and M5, bolts of ISD-C03-500Y(Cross-recessed head machine screws(In compliance with GMW3059))and ISD-C03-503Y (Hexalobular socket head machine screws, pilotpoint (In compliance with GMW3059)) shall be used respectively.
2. Where bolts should be used at 200℃ or higher, attention shallbe paid for reduction of tightening axial force and materialstrength because bolts of this standard are made of boron steel,tempering temperature of which is low.
