MATERIALS AND FINISHES
Low Carbon Steel (F)
Low carbon steel is one of the most versatile materials
available. This material is readily available, and is the
most economical of the standard Solid Pin materials in the
absence of any plating or coating. Low carbon Solid Pins
have a dry to the touch rust preventative. Additional coatings
and finishes can be applied to carbon steel to improve
corrosion resistance, however for some applications, it may
be more appropriate and cost beneficial to specify stainless
steel when a high level of corrosion resistance is required.
Austenitic (Nickel) Stainless Steel (D)
Austenitic stainless steel provides excellent corrosion
protection against normal environmental conditions. It
withstands fresh water and atmospheric marine conditions
very well, and is suitable for many other industrial conditions
including acidic environments. All austenitic stainless Solid
Pins are passivated.
This finish is a thin coating of dry-to-the touch oil that
provides corrosion resistance during storage and shipping.
Since this lubricating oil is suspended in a carrier which
evaporates over time, the pins are dry-to-the-touch and
conducive for automatic feeding and assembly.
Passivation of stainless steel Solid Pins is a process
whereby surface contaminates such as embedded tool steel
and other free iron particles are removed. The sole purpose
of passivation is to remove embedded iron; not to clean the
part. While all stainless steel Solid Pins are passivated as a
standard, there are some critical applications that absolutely
require passivation such as medical devices, components
used in the food or drug industry, fuel system applications,
and any application requiring a clean environment.
Available only for stainless steel.

SPIROL has extensive experience with special materials required for unique circumstances such as:
Alloy Steel (W)
Alloy steel is used for applications requiring higher shear
strength than our standard materials provide, or when
additional hardness is required to ensure that the pin is harder
than the host material into which the pin is being installed.
Aluminum is lightweight, lead free, and has sufficient strength
for most plastic applications. Aluminum is less than half
the weight of steel, and does not require any supplemental
coatings or platings to provide the necessary corrosion
protection in most environments.
Other materials and finishes are available to order depending on the application requirements.
Innovative fastening solutions.
Lower assembly costs.
