Standard Metric Nut and Bolt Torque Recommendations
This information is for reference only. The user must check that the torque figures listed here are applicable
to the fasteners used. Nuts and bolts should be neither under nor over tightened.

Note: These torque figures are approximate, and for unplated fasteners only. No allowance has been made
for special finishes or lubricants, washers or mating surfaces.
Bolt and Nut Grade Combinations
Grade of BOLT 4.6 8.8 10.9 12.9 Note: It is permissible to fit
higher grade nuts than
recommended.
Grade of NUT 4 8 12 12
Grade Identification
BOLTS & NUTS - Grade 4.6
BS4190 (ISO272, 885, 888 & 4759/1). Grade marking is optional. Normally there will be no
mark other than the 'M' thus:
BOLTS - Grade 8.8
BS 3692 (ISO272, 4759/1). Grade
marking is mandatory, may also have
trademarks. NUTS - Grade 8
Indented marks as a clock face, dot at
12.00, bar at 8.00, indicates grade 8
nut.
