08-8 GENERAL INFORMATION
USE OF METRIC AND CUSTOMARY NUTS, BOLTS AND SCRERS
Some veh~cles present spec~al servlce requ~rements to the technrc~a~l due to the use of both metnc and cus-
tomary
(Inch) type nuts, bolt5 and screws. Many are metnc and some are very close in d~mens~on to custom-
ary nuts. bolts and screws in the
Inch system M~smatched or Incorect nut5, bolt5 and screus can result rn
damage, malfunct~on or poss~ble personal Injury Nuts. bolts and screws removed from the veh~cle 5hould be
saved for re-use
uhenever poscrble. If they are not re-usable. care should be taken to select a replacement
that matches the
ong~nal.
General Motors Eng~neenng Standards have ddopted a portion of the standard metnc fastener slzes defined
by SI (Systeme
Internatronal) Th~s was done to reduce the number of srzes used and yet retarn the best
strength
character~st~cs In each thtead size. For example. the customary 114-20 and 1/4-28 screws are replaced
by the
metrlc M6.3 x I screw wh~ch has nearly the same d~ameter and 25.4 threads per inch. The thread p~tch
IS In between the customary coarse and fine thread prtches.
Metnc and customary thread notatlon d~ffer sl~ghtly. The d~fference IS ~llustrated belou.

METRIC BOLT AND NUT IDENTIFICATION
Common metric fastener strength property
classss are 9.8 and 10.9 with the clers idsntifica$ion
embossed on the haad of each bolt. Customary (inch) strength clases range from grade 2 to 8 wi(h
line ihntificaion embosssd on each bolt head. Markings correspond to two lines lsss than the
actual grade
(i.e. grade 7 bolt will exhibit 5 embossd lines on the bolt head). Some metric nuts will be markd with single digit strength identification numbers on the nut face. The following figure
illustr&es the different strength markings.
Customary (~nch) bolts - ldent~f~cat~on marks correspond to bolt
strength - lncreas~ng numbers represent lncreaslng strength.
Metr~c Bolts - ldent~f~cat~on class numbers correspond to bolt
strength - lncreas~ng numbers represent lncreaslng strength.
