Boltinox

What Boltinox does

Boltinox Ltda. is a Brazilian manufacturer and wholesaler of stainless steel fasteners, founded in 1994 and headquartered in the Tatuapé district of São Paulo. The company specializes in corrosion-resistant stainless steel products — screws, nuts, washers, threaded rods, anchor bolts, and custom-made items — primarily using austenitic 300-series stainless steel (types 304 and 316) and applying a post-stamping passivation treatment to enhance corrosion resistance. Its catalog is organized into four vertical-specific product lines: photovoltaic solar mounting hardware, window and door frames (esquadrias), sanitary installations, and glass applications, with sub-products conforming to international standards such as DIN 912, 933, 603, 7504, 934, and 985.

The company's operations are grounded in metallurgy and quality-controlled manufacturing rather than software or data technology. Boltinox has held ISO 9001 certification issued by SGS (Société Générale de Surveillance) continuously since 2004, and every batch shipped to customers is accompanied by a quality certificate documenting material grade, production lot, and technical conformity, providing full traceability. The team is described as composed of professionals with more than 40 years of industry experience, and Boltinox positions itself as a pioneer in stainless steel fastener manufacturing in Brazil.

Commercially, Boltinox operates a direct-to-customer B2B model without intermediary distributors, conducting all sales interactions via WhatsApp, phone, and email. The company offers an automatic stock replenishment service that monitors and restocks customer inventory on a recurring basis, and pricing is quote-based rather than published. Its customer base spans Brazilian industrial and construction-adjacent buyers across four end-use verticals. The firm is privately held, has no disclosed external investors or parent company, and operates with a small staff (1–10 employees).
