Appropriate plating or coating processes should be employed to avoid hydrogen embrittlement . When pins are electroplated or phosphate-coated, they shall be suitably treated immediately after plating or coating to obviate detrimental hydrogen embrittlement, although freedom from hydrogen embrittlement is not absolutely guaranteed. Preferred coatings are chemical black oxide or non-electrolytic zinc plating. Other coatings as agreed between customer and supplier. 所有公差僅適用于涂、鍍前的公差。
不允許有不規則的和有害的缺陷。銷的任何部位不得有毛刺
