Name that bolt/nut/screw size - Page 2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**DeadheadNM** · 06-27-2014, 07:38 AM

Gravel guard uses Phillips head bolt, 1/2" nut, and a star washer as shown on this 72 example I believe is untouched since left GM

**DeadheadNM** · 06-27-2014, 07:39 AM

Hatch handle uses tapered head Phillips head screw 1.25" long

Dale99 · 06-27-2014, 07:42 AM

So 1/2 nut would mean 1/4 threads IIRC?
That screw looks like it would be a #8 or #10??

Thanks for the pics!!!

Sorry not sure re: the sizes otherwise but happy to help with pics

Dale99 · 06-27-2014, 07:51 AM

I looked up, it would be 5/16 threads on gravel guards.

Dale99 · 06-27-2014, 07:58 PM

Hatch handle screw is #8-1.25"

Yeah that's the "normal" standard. 1/4" bolts have a 7/16" head and nut, 3/8" bolts have a 9/16" and a 7/16 bolt has a 5/8". There are possible variations like those 12 point hood latch bolts but these are normal I.D. for buying bolts.

Instead of "tapered" those screws would be called "countersunk" I have an unmolested '70 Jimmy partially tore apart that may provide some info you are wanting on this thread.

The rear seat hold down bolts are a 7/16" fine thread, as well as the seat belt bolts front, rear and the threaded holes in the roof where a shoulder harness was possible.

Great thread!---DAC

Well, sorry. I just went off some of these posts from earlier today. Have read it all but memory isn't so good at my age I guess.

Anyone know what screw is used to hold the hatch handle to the hatch?

I tried to order from MSC and they sent me to www.totallystainless.com. These guys seem to have everything.

I have none of the bolts for my spare tire carrier, so I'll be waiting eagerly for this info. I appreciate you taking the time to do the research. My spare tire carrier goes to powder coat next week and I want to get the bolts done as well.

**DeadheadNM** · 11-01-2014, 04:58 PM

Still digging - I know I have some. They are similar to these seat bolts removed from a suburban but IIRC the head was larger and not as tall, fine thread maybe 1/2"?

**DeadheadNM** · 11-01-2014, 05:00 PM

Examples of carb stud and wing nut to attach the air cleaner to the carb

EDIT: The stud is 6 7/16" in length

Rubber upper rad heater hose w part # and tower clamps (from my 72 K1500 GMC but should be same for K5) - a segment of the metal hose can be seen.

**DeadheadNM** · 11-01-2014, 05:03 PM

Bracket to affix the power steering hoses to the frame

Dale99 · 11-01-2014, 10:12 PM

Spare tire bolts are 7/16-20 X 1.00 with outtie star washers. They are 5/8 socket. I broke one of mine off and going to have to tap and find another.

Dale99 · 11-01-2014, 10:17 PM

The screws that hold the cap onto the top of the door are #8x.50 Countersunk oval.

Sweet! Thanks. I need to locate 4 of these.
