"PK" COMMERCIAL SHEET METAL SCREWS
Return To Top
Since AN, NAS and MS part numbers do not cover every possible sheet metal screw
configuration, a full line of commercial screws are offered. These are
available in type A style (pointed tip) and type B (blunt tip and slightly
finer thread pitch). Type B should be used with tinnerman nuts and any
application where the tips are exposed, such as shrouding, etc. Plating on
steel screws is bright zinc. Stainless steel screws are also available with the
"PS" prefix.
