911 Bolt Library

[Shaun 69 E]

For some time now I've been cataloging both the size and application of hardware in longhood through impact bumper cars. In addition to application, I am also detailing the bolt manufacturer. My reasoning being you wouldn't want to use a KAMAX from an 85 car when a DERA was specified for 69.

Recently a member asked if I had 12 8x20 hex head bolts specific for the door hinges on his 73. Sorting out some of my newly plated hardware, I found 15 unique manufacturers of this size bolt and stopped when I found 12 really nice KARROs.

I could use some help in building this library. My spreadsheet columns include
Group (from PET)
Application (what it's used for)
Head (head, cheese hex, triple square)
Quantity
Size
Thread pitch
Total Length
Grip Length (smooth part of shank if it has one)
Stength
Nut
Washer 1
Washer 2
Special (any kind of special details like a beveled, notched tip)
Year
Manufacturer

If you have a known original car and don't mind posting details of your hardware through the normal course of doing work on your car, we would all benefit from it.

Manufacturers I have found so far:
Karro
Verbus
Kamax
Dera
Lobo
Graeka
Nedur
F+H
3F
Dorn
Arbed
Omel
Ribe

This is getting so correct it hurts my head.

[37yrold911]

it would be more correct if it was called "cap screws"

How about what type of finish? (white zinc, yellow zinc, cadmium, etc.)

This is why I swore I would never do another frame off trailer queen

Keep it up, Shaun. To each his own

I admire your courage. Tenacity will be the next test.

The BMW VMCA guys have all this stuff down to a fine science for the bikes. Next trick is the plating. Finding a good reputable shop that can do Cad, Zinc, Black Oxide, Chrome, Nickel etc etc. is the hurdle. Preparation is the key to any good finish, even on nuts and bolts. The cleaner they go in the better they look coming out.

Good luck!

If PCA were like a real car club this would all be in their judging manual. Most marques have collected this information years ago.

We owe you a huge thank you.
