[Collins] Need Screw for 312B-2

[Dr. Gerald N. Johnson]

By tapered head I presume you mean flat head or oval head. Collins would 
have used stainless steel phillips flat head. I didn't find any that 
long in my bins, but I did find 2-1/2" at Mc Master-Carr. They take 
plastic, like to think they are selling to a company. These come in a 
box of 100 for $5.80 plus shipping. I'm sure they can be cut back to 
2-1/4" but not easily, stainless steel tends to be tough compared to 
ordinary steel or brass.
