Cylinder stud (1-1/2 in. O.A.)
A 1-1/2 in. cylinder base stud used in the crankcase, listed under alias E3820.
This is a cylinder stud, 1-1/2 in. overall length, listed under the crankcase section of the parts books. It's one of the studs that clamps the barrels down to the crankcase mouth, so it's a fundamental fastener for keeping the bottom end and cylinder block sealed together under compression.

The legacy alias E3820 is the same physical stud as 70-3820 — if your parts book still uses the old letter-prefix numbering you'll find it listed that way. Catalog appearances for this stud run from 1964 to 1968.
If you're replacing a full set, it's worth pulling the old ones and checking for stretch or thread damage before ordering just one. Confirm fitment against your specific engine before you order — the crankcase stud pattern can vary.
