力(li)(li)矩(ju)(ju)扳(ban)(ban)手(shou)(shou)(shou)(shou)又叫(jiao)扭矩(ju)(ju)扳(ban)(ban)手(shou)(shou)(shou)(shou)、扭矩(ju)(ju)可調扳(ban)(ban)手(shou)(shou)(shou)(shou)，是(shi)扳(ban)(ban)手(shou)(shou)(shou)(shou)的(de)一種。按動(dong)力(li)(li)源可分為(wei)：電動(dong)力(li)(li)矩(ju)(ju)扳(ban)(ban)手(shou)(shou)(shou)(shou)、氣動(dong)力(li)(li)矩(ju)(ju)扳(ban)(ban)手(shou)(shou)(shou)(shou)、液(ye)壓力(li)(li)矩(ju)(ju)扳(ban)(ban)手(shou)(shou)(shou)(shou)及手(shou)(shou)(shou)(shou)動(dong)力(li)(li)矩(ju)(ju)扳(ban)(ban)手(shou)(shou)(shou)(shou)；手(shou)(shou)(shou)(shou)動(dong)力(li)(li)矩(ju)(ju)扳(ban)(ban)手(shou)(shou)(shou)(shou)可分為(wei)：預置(zhi)式(shi)(shi)、定值式(shi)(shi)、表(biao)盤式(shi)(shi)、數顯式(shi)(shi)、打滑(hua)式(shi)(shi)、折彎式(shi)(shi)、以(yi)及公斤扳(ban)(ban)手(shou)(shou)(shou)(shou)。當(dang)螺釘和螺栓的(de)緊密度至關重要的(de)情況下(xia)，使(shi)用扭矩(ju)(ju)扳(ban)(ban)手(shou)(shou)(shou)(shou)可以(yi)允許操作員施加特定扭矩(ju)(ju)值。

力矩扳(ban)手就(jiu)是緊固(gu)螺(luo)栓的，高強(qiang)螺(luo)栓可分(fen)為(wei)扭剪型和大六角(jiao)(jiao)型兩種(zhong)(zhong)，國(guo)標扭剪型高強(qiang)螺(luo)栓為(wei)M16、M20、M22、M24四種(zhong)(zhong)，現在(zai)也有(you)(you)非國(guo)標的M27、M30兩種(zhong)(zhong)；國(guo)標大六角(jiao)(jiao)高強(qiang)螺(luo)栓為(wei)M16、M20、M22、M24、M27、M30等幾種(zhong)(zhong)。一(yi)般的對于高強(qiang)螺(luo)栓的緊固(gu)都(dou)要先初(chu)緊再終(zhong)緊，而且每步都(dou)需要有(you)(you)嚴格的扭矩要求。大六角(jiao)(jiao)高強(qiang)螺(luo)栓的初(chu)緊和終(zhong)緊都(dou)必須使用定扭矩扳(ban)手。
