Question
dear Mr Crawford,

Specification of a bolt reads
BOLT HEX PM 24x150 -8.8/R36
What each mean?
PM?,
24X150?
8.8?
R36?

Regards
sabu isac

Answer
This nomenclature matches no designation sequence I know of and may be in parlance with the manufacturer, or user

I cannot be confident of my interpretation of these meanings and can only give my best guess.

PM, Preventive Maintenance

24 x 150 may be the bolts size, or bin location as there are no measurement symbols or abbreviations.

8.8, designation of composition of the bolt,

R36, possibly thread pitch, for matching it to a threaded hole, or bolt.

Again sorry I can have no better confidence in this matter.
