トルクと軸力の重要性

安全・確実にボルトを締結するための第一歩は、正確なトルクと軸力で締付作業を行うことです。ボルトの締付トルクとは、ボルトを締め付ける時に加える回転力のことで、ボルトを締め付けて締結力（軸力）を得るために使用する力のことです。

ボルト締結で最も重要なのはこの「軸力」です。ボルトは締め込まれることで引き伸ばされ、引き伸ばされたボルトには元に戻ろうとする力が作用し、この力が締結されるパーツ同士を挟み込んで固定します。通常は各ボルトが発揮すべき軸力値はその設計者によって算出されており、そこから逆算して締付トルクが決定されます。

トルクによる締付では、校正された工具を用いて既定のトルクをもって締め付けることで正確な軸力を得ます。注意すべき点としては、締付時と取外し時で必要トルクは変化するということです。

エキスパートに相談

当該のボルト締結体に適したトルクの割り出しにお困りの場合は、テクニカルサポートまでお問い合わせください。

締付トルク目安表

ノルトロックワッシャーを使用して、M3～M42のあらゆるサイズのボルトのトルクと軸力の目安を得るには、ガイドをご利用ください。また、潤滑剤には様々な種類があります。摩擦値は、コーティング、潤滑、潤滑油の種類によって異なります。

1) For additional rotation angles  EN 1090-2 Table 21 applies

Torque Guidelines Steel Construction Washers, Table 3

Additional rotation for the second step in the combined method (8.8 and 10.9 bolts).

Total nominal thickness "t" of parts to be connected (including all packs and washers) d = bolt diameter	Further rotation to be applied, during the second step of tightening
	Degress	Part turn
t > 2d	60	1/6
2d ≤ t < 6d	90	1/4
6d ≤ t ≤ 10d	120	1/3
10d < t	No recomendations

Tightening angles when using the combined method varies depending on the clamp length, (t), in relation to bolt diameter, (d).
