Shoulder
Screws
Shoulder screws feature a socket head, a close tolerance
body, and a threaded portion smaller than the body.
The area under the head may be undercut so that the
head will seat on the work surface. The threads may
be undercut so that a nut will go all the way to the
end of the shoulder. Shoulder screws are often referred
to as "Stripper Bolts".
Almost
everybody in the fastener business can provide shoulder
screws in Alloy Steel or 303 Stainless. If more corrosion
resistance is required these parts would have to be
made. Nickel Systems maintains an inventory of raw material
in Alloy C276 (Hastelloy ®), Alloy 20 (Carpenter
20®), Alloy 400 (Monel®), 316 Stainless, and
other non ferrous materials should you have a requirement
is these areas.
