A NOTE FROM BOKER’S
We are pleased to bring you the Boker’s, Inc. 2023 Stampings Washers Catalog. For over 100
years, we have been honored to provide stamped components and washer solutions to every
market and industry to date.
As you are likely aware, our lead times in 2021 and well into 2022 were longer than they ever
have been. Globally, manufacturers faced the same challenge of re-stocking the world after the
pandemic shutdowns left retailers and distribution centers empty and OEM’s work-in-process
nearly diminished.The overwhelming increase of “super-sized” orders led us to a point where our
capacity was booked out further than ever before.We have now dug out of our backlog and
have made major strides in meeting or exceeding customer on-time delivery expectations.
Boker’s understands that long lead times have an adverse effect on our customers and their
ability to plan and execute; we are excited to announce that Boker’s team continues to work hard
and has significantly reduced our lead times to provide you, our customer, with world-class service.
As we continue to drive our lead times back down to the quick delivery we are known for, please
reach out to understand the lead time required to manufacture your order. Our lead times are
back, and we are stronger than ever.
As always, it is our pleasure to be at your service. Amy Kersey
CEO/President
3. It all began in the Minneapolis basement of a young,
passionate and focused man named Vitus Boker. He
instilled the values of hard work and attention to detail
throughout the company as it grew. These values still
guide the company today, which inspires the team to
provide an exceptional customer experience while
producing the highest quality component parts.
Being a value-driven company also means giving
back and being good stewards for the surrounding
community. From drawing skilled tradespeople from
across the Twin Cities to volunteering with local non-
profits, Boker’s brings passion and attention to detail
to everything we do.
A Part of Every Industry
Boker’s has been serving companies on the forefront
of technology innovation for over 100 years. As a
result, you come into contact with components that
Boker’s has manufactured almost every day. From
airplanes, appliances and medical devices to outdoor
recreational equipment, furniture and renewable
energy, you interact with items that feature stamped
components manufactured by Boker’s.
Customers trust Boker’s because of their quality, on-time
delivery and service. Often times, customers come
with a difficult part that they were struggling with and
Boker’s figures out how to manufacture the part to their
exact specifications.
Continuing the Legacy
Boker’s works in and serves all fast-paced and high-
demand industries. Over the past 100+ years, we have
embraced and been on the forefront of technology
evolution and integration.
The future of Boker’s is sticking to our wheelhouse of
what we are known for while expanding our customer
base and serving emerging markets. We will continue
to expand capabilities by adapting and pursing new
technologies and processes in an effort to continue
exceeding customer expectations.

Quality Stampings
Made to Order
Vitus Boker launched the company based on pioneering the production of high-quality, short-run stamped metal parts.
With over 100 years of experience, Boker’s has earned the reputation as a stamping leader and the respect of many
customers for their specialized metal components.
Draws, Forming, Blanking and Piercing
At Boker’s, we utilize the latest stamping technologies and manufacturing concepts to
continually provide you with stampings of the highest quality. This diligent effort to achieve
and retain the highest quality possible in our metal stamping processes goes back to 1919.
Production Process Overview:
•
In-House tool and die department designs and produces custom tooling to be used
in the stamping process.
•
Material warehouse shears sheets of material into strips or issues a coil of
material—metallic or non-metallic.
•
The material then transfers to the production floor to be stamped using the custom
or stock tool(s) in one or more of our many varieties of punch presses.
•
Parts are then (in any combination) blanked, deburred, formed, drawn, tapped or
pierced in-house. After in-house production is complete parts may be sent to an
approved vendor for plating, heat treating, grinding, or testing before going to
Boker’s Quality Assurance Department. In our Q.A. Lab, parts are inspected to
ensure they meet customer specifications before being released for shipping.
Draws up to 3” deep
and 8” in diameter
Flat blanking and
piercing up to 12” by 12”
Complex metal forming needs
in thicknesses from .005” to .190”
