Mystery Screw - RS 5484 B7

Need more info. There are many different types of screws. The number could be the OEM part number.

I would, very cautiously I must note, harber a guess that the B7 part of it pertains to the ASTM A193 grade B7 specification - and that the other 'RS 5484' is a manufacturers number.

Is this part actually a 'screw' or is it a hex cap bolt (screw), or stud, or .............

yes, It is a hex cap bolt (screw). the printed words are just on the hex cap.

Then there is a 90% chance that it is a standard B7 bolt as per A193.

One last quick check/question - would this application require high strength at high temperatures? If so, that is what the B7 grade is used for.

Oh yeah - as for your question where to get them - they are a very common grade of bolt and any reputable supplier should easily have them.

yes, the bolt is required to have high strength,(I guess it is class 10.9 or 12.9) but high temperature is not neccessay?

additionally, the bolt is required to have very stable yield stress and ultimate stress

"...a screw from a device..."

Is there any reason the manufacturer of this "device" can't supply you with either the information, or even a supply of the hardware?

bolts from the device supplier are very expensivie . and I hope to get the bolts directly from bolt supplier.
