鉄 10.9強力六角ボルトのサイズ表:定番ショッピング

品名:鉄 10.9強力六角ボルト

名称:10.9強力六角ボルト 全ねじ/半ねじ

〇特徴

 六角形の頭を持つおねじの締結部品です。熱処理されているため引張強度が10.9と高くなっています。締め付けは片口スパナ、両口スパナ、めがねレンチ等が使われます。

ねじが首下まで切られているもの(全ねじ)と軸部の途中までねじが切られている(半ねじ)ものがあります。全ねじの場合は「全ねじ」と指定する必要があります。指定しない場合は半ねじとなります。また、軸部の長さが短いものは「全ねじ」と「半ねじ」の区別がありません。

〇規格

 市場ではJIS B 1180附属書(旧JIS)等

 ねじ部の規格はメートル並目ねじ(JIS B 0205)です。

〇材質

 SCM435のような鉄鋼を使い、熱処理をして引張強度をあげています。強度区分(10.9)が頭部に刻印されています。

〇表面処理

 生地以外にメッキ品はユニクロ、三価ホワイト、三価ブラック他多くの種類が市販

材質:鉄(主にSCM435)

 機械部品等に使用される鉄は純粋な鉄ではなく、炭素・ケイ素・マンガン・リン・硫黄等の元素が含まれた普通鋼や普通鋼に特殊な元素が加えられた特殊鋼が使用されます。SCM435は普通鋼の中に特殊元素(クロム、モリブデン等)を微量に添加して焼入れ性を向上させた機械構造用合金鋼です。国内で普及している六角穴付きボルト、10.9強力六角ボルト、六角穴付き止ねじ等はSCM435が使用されています。焼入れ性がよいため、焼入れ・焼き戻しをして強度をあげて使用することが多いです。

表面処理:生地

 表面処理を施していない、素材そのままの状態です。鉄の場合は生地の状態では錆が発生するため、通常は防錆油を塗布しています。また、ねじ業界では材質が鉄で熱処理をして黒色酸化皮膜を形成したものを「生地」という場合があります。また熱処理後に黒色酸化皮膜を除去したあとに、表面処理の黒染めを行う場合があり、黒色酸化皮膜+防錆油塗布のものも「生地」と呼ぶ場合があります。
