What M & S Spring Company, Inc. does

M & S Spring Company, Inc. is a U.S.-based custom manufacturer of precision coiled springs and related metal components, founded in 1960 and operating as a division of Lee Spring Company LLC. The company produces compression, extension, torsion, and garter springs, along with wire forms, metal spring clips and fasteners, and light stampings, across wire diameters from .006 to .625+ inches and material thicknesses from .010 to .080 inches. Its material portfolio spans high carbon steel, stainless steel grades 302/304/316/17-7 PH, alloy steels, and high-temperature alloys including Inconel 600 and X750, enabling applications up to 1100°F.

The firm holds ISO 9001:2015, AS9100 aerospace, and ITAR defense certifications and supports prototype quantities through production runs of millions of parts. Customers submit quotes via online forms, email, phone, or fax with drawings or samples; pricing is quote-based and products ship FOB Origin from the Fraser, Michigan manufacturing facility. Sales are executed through a direct B2B motion with no channel partners or distributors. The customer base exceeds 2,000 active clients across automotive, aerospace, military and defense, and a broad non-automotive industrial set including construction, appliance, marine, medical, and electronics. Marketing relies on the company website, Google AdWords remarketing, and Facebook and Twitter remarketing.

Supporting the manufacturing operation is a customized Customer Order Management System (COMS) and in-house spring design software used for accurate design input and engineering support. There are no disclosed AI/ML capabilities, no M&A activity, no outside funding rounds, and no recent leadership or structural changes in the source material.
