About EXTSW

EXTSW specializes exclusively in high-quality 304 and 316 stainless steel washers and spacers.

With over 40 years of experience in stainless steel fabrication—primarily serving the beverage and dairy equipment industry—we understand the importance of precision, durability, and material reliability.

We originally began making extra-thick stainless washers and spacers for our own fabrication projects. After customers started asking if they could purchase them, EXTSW was created. Today, manufacturing washers and spacers is our entire focus.
