The GMC CCKW

According to TM10-1562 Parts List, I need about 100 screws number 2140091. I cannot find in any ORD9 or any other CCKW manual what is the description of this "Screw-retainer". Is it a philips head, clutch head, what size, etc. Any one have an idea?

This is used for MANY applications throughout the Closed Cab's. Thanks in advance. Paul

All of the original screws in my closed cab were clutch head.

Bought a bag of 100 #10-24 1/2" long years ago from Jimmy Carter Chevy parts.

Also used them in the Chevy G506.
