About EXTSW
EXTSW is operated by Thomas Richard Hoffman.
EXTSW specializes exclusively in high-quality 304 and 316 stainless steel washers and spacers, manufactured in the United States for precision, durability, and long-term reliability.
We have been making and selling stainless washers and spacers since 2015, backed by over 40 years of experience in stainless steel fabrication—primarily serving the beverage and dairy equipment industry. We understand the importance of consistent materials, accurate sizing, and dependable performance.
EXTSW began when we started producing extra-thick stainless washers and spacers for our own fabrication projects. As customers began requesting the same parts, we launched EXTSW to make these components available to others. Today, washers and spacers are our entire focus.
Seller Reputation
