Default Rear cargo area load securement holes

Anyone happen to know the bolt size for the rear cargo area tie down spots? After covering over the holes under driver side rear seat from fuel pump repair I lined up the carpet better and note the holes. Bought used, nothing in them but prior owner must’ve had something there with the dents in carpet around them. Would like to put some round head bolts in with tab rings from local home improvement place but really needed to know size type. ? Like are they 1/2” corse thread or what? Note spots in pic on carpet- those are what size? Could not find it on forum nor with web search but my “google-foo” is poor.



What size are these holes and thread type?

Default Found them 3/8” corse thread

3/8” corse thread. Got 4 “D” ring hooks and bent tab under for loop. Drilled to match bolts. All good. Thanks.


3/8” corse thread. Guess length depends on need.

D ring, tab folded under and drilled. Rated 400 lbs which more than enough.

Good to go, now can tie down things like my Kerosene and gas cans.

Interesting. What year is your Blazer? My 2000 was definitely metric.

Nice. Good to know, always wondered how much those little things could hold...

98, I know the bolts fit, tightened up enough with cordless impact I had to back em off, the hooks would not move. Maybe because corse thread close enough to hold tight? Quick metric conversion shows about 9.5mm, I just took a bolt I found in my junk box that seemed to fit hole to Menards, it fit the 3/8” corse thread test board they have in bolt/screw isle and ran with that. 5$ for a 4 pack of the tie down hooks and .99 per bolt- wanted rounded head with no sharp edges so went with that hex drive type. FIts the need in this case for mainly keeping kerosene and gas cans from moving.
